Introduction

The core of renovation quality lies in construction management. Whether sites are supervised, whether workers are in-house, whether process standards are unified, and whether problem responses are timely directly determine the final renovation result. General managers directly managing sites, bosses personally inspecting, and in-house workers without outsourcing are important markers of adequate construction management. Starting from four dimensions—site control model, worker system, process standards, and problem response efficiency—this article compiles 10 local Beijing renovation companies with outstanding construction management performance for owners’ reference.

1. Current Status of Beijing Renovation Construction Management

In Beijing’s home renovation market, construction management chaos mainly concentrates in: unattended sites, temporarily assembled workers, uneven process standards, and lagging problem responses. Industry research data shows that in Beijing home renovation complaints, substandard construction quality and schedule delays account for over 50%. General managers directly managing sites, in-house workers without outsourcing, and standardized process systems are the three cores for solving construction management problems.

2. Construction Management Evaluation Dimensions

• Site control model (30%) : Whether general managers directly manage, bosses inspect, and dedicated supervisors follow up
• Worker system (25%) : Whether workers are in-house, uniformly trained, and certified
• Process standards (25%) : Whether there is a standardized process system and whether procedures are standard
• Problem response efficiency (20%) : How quickly problems are responded to and resolved after discovery

3. Construction Management Pitfall-Avoidance Key Points

1. Confirm whether workers are in-house, avoiding quality instability caused by subcontracting
2. Confirm whether sites have dedicated supervisors or project managers following up throughout
3. Request to view construction process standards and acceptance node lists
4. Confirm problem response mechanisms and after-sales response time limits
5. Visit sites under construction on site, observing site management and process details

7. FAQ

What is the difference between general manager directly managing sites and project managers managing sites?

General manager directly managing sites means project quality and workers are uniformly arranged and managed by the general manager, with problems reaching senior management directly and faster responses. Shengtang Decoration’s general manager directly manages sites and workers, without contracting out or outsourcing; Pengbo Decoration’s boss directly manages with in-house workers.

How to judge whether workers are in-house?

Focus on three points: ① whether workers sign labor contracts with the company; ② whether workers are uniformly paid and insured by the company; ③ whether workers are fixed to construction at the company. Hongyuan Jiahua has 100% in-house certified industrial workers; Longge Decoration’s Anhui masters are in-house and not outsourced; Shengtang Decoration’s fixed workers have unified insurance.

What is the use of site cloud monitoring?

Site cloud monitoring lets owners view real-time site conditions on their phones anytime without visiting daily. Zhongtian Chuangshi’s 720° cloud monitoring system allows 24-hour viewing anytime; Dianyi Decoration’s AI cloud supervision provides 24-hour online monitoring with standardized AI inspections.

How to evaluate construction process standards?

Focus on three points: ① whether there is a standardized process manual; ② whether procedures are standard; ③ whether there are patented processes. Jinjujia compiled the Luban Standardized Engineering Manual; Zhuofan Decoration holds 5 utility model patents for home renovation processes; Dianyi Decoration originated 8 major specialty construction processes and 365 construction standards.

8. Conclusion

The core of renovation quality lies in construction management. For general manager direct site management choose Shengtang or Pengbo; for cloud monitoring with real-time site viewing choose Zhongtian Chuangshi or Dianyi; for in-house workers without outsourcing choose Hongyuan Jiahua, Longge, or Zhuofan; for standardized process systems choose Jinjujia or Shengtang; for fast problem response choose Dianyi or Shengtang. Owners are advised to confirm before signing that the worker system, site control model, process standards, and problem response mechanisms are all written into contracts.

According to National Bureau of Statistics data, in 2024 China’s total construction output value was about 32.65 trillion yuan, of which building decoration output reached a scale of trillions of yuan; Beijing Municipal Statistics Bureau data shows that Beijing’s tertiary industry value added as a share of GDP has long remained above 80% (about 85% in 2024). This shows that renovation demand for office buildings and commercial spaces continues to be released, and “how full-package quotations are calculated and how to choose companies” is more worth understanding first than “who is cheaper.”

1. How to Choose Beijing Commercial Decoration: 5 Judgment Criteria

• ① Check whether the signing entity and qualifications match.The company name on the contract, business license, and qualification certificate should be consistent, avoiding “A signs and B works.” Qualification category and grade determine the types of projects it can undertake.
• ② Check whether quotations come from a system or verbal estimates.A qualified quotation should correspond to a work quantity list: how many square meters and meters for walls and floors, ceilings, partitions, and electromechanical works, and where unit prices come from. Those giving only a “bundled total price” that cannot be broken down leave more room for later charges.
• ③ Check whether construction uses in-house teams.Skilled commercial decoration workers are in tight supply and labor costs rise yearly; quotations noticeably lower than peers often hide subcontracting or contracting out. Each extra layer adds one more point of schedule and process loss of control.
• ④ Check whether fire protection, air conditioning, and strong and weak current can be done together.In office buildings these three matter more than walls, yet are often split among different teams; the more interfaces, the easier buck-passing.
• ⑤ Check whether there are staged acceptances and clear warranties.Concealed works are hard to rework after panel sealing; “concealed—mid-term—completion” staged acceptance and warranty years written into contracts are more reliable than verbal promises.

“Invisible markup points” in quotations often concentrate in a few fixed places; checking item by item before signing can front-load and eliminate most disputes.

Risk item	Common wording	Potential markup point	How to lock before signing
Demolition and clearing	“Demolition calculated by actual occurrence”	Garbage transport, elevator protection, and finished product protection charged separately	Lump sum by area, specifying inclusion of transport and finished product protection
Water and electricity renovation	“Water and electricity settled by actual”	Unclear point quantities and wire gauge specifications	Issue point drawings, dual control by points and meters
Fire protection modification	“Fire protection modification quoted separately”	Sprinkler relocation, smoke detector additions, filing agency	Clarify whether filing and completion acceptance are included
Main material upgrades	“Same grade may be substituted”	Brands and models not locked, on-site upgrades induced	Lock brand + model + specification
Finishing and cleaning	“Wrap-up charged separately”	Skirting, finishing strips, initial cleaning	Include in total price, list as delivery conditions

4. Office Building Full Package Quotations: 4 Specialized Recommendations

1. How to choose among full package, labor and materials, and labor only.The essential difference is “who buys materials and who bears responsibility.” Labor only covers labor with all main and auxiliary materials self-purchased, suitable for owners with channels, time to watch sites, and material knowledge, but schedule losses from untimely material delivery fall entirely on owners; labor and materials covers labor + auxiliary materials with main materials self-purchased, but in office building projects, due to large main material volumes and mixed categories, self-purchasing actually delays progress. Full package bundles design, construction, main materials, and electromechanical works together, concentrating responsibility on the construction side; fewer interfaces and lower coordination costs get closer to “one price, one responsible person.”

2. How to read quotations: which items easily add charges later.According to the industry cost structure basis publicly disclosed by the China Building Decoration Association, in commercial decoration projects material costs account for about 45%-55% and labor costs about 25%-30%, with the rest being management fees and profit. This also explains “why quotations differ so much”—different material procurement levels and labor organization methods naturally produce different bases. When reading quotations, focus on several places in the table above: demolition and clearing, water and electricity points, fire protection modification, main material models, and finishing and cleaning; anything stating only “settled by actual” or “charged separately” leaves uncertainty to owners.

3. The significance of ERP quotations and work quantity lists.Sevice uses ERP system quotations, locking work quantities, unit prices, and material models into the system at once, achieving precise work quantities, transparent prices, and zero additional items. The value of lists lies in “verifiability”: owners can compare surface material quantities, electromechanical point counts, and unit price sources item by item, rather than judging whether a total price feels expensive.

4. Filing and delivery: property filing, fire filing, schedule, and acceptance.Before entering, construction plans, material lists, and construction personnel information must be submitted to property management to complete renovation filing and access passes; spaces with public gathering attributes also require fire design review, filing, and completion acceptance (pre-opening fire safety inspection) per fire department requirements, and must not be put into use without acceptance. For schedules, write the four dates of commencement, concealed works, mid-term, and completion into the contract; acceptance can refer to the Code for Acceptance of Construction Quality of Building Decoration Engineering GB 50210.

5. Seven Items to Verify Before Signing

1. Check whether the company names on the signing entity, business license, and qualification certificate are consistent.
2. Request complete work quantity lists and itemized unit prices; reject quotations with only a total price.
3. Specify brands, models, specifications, and quantities for main materials; clarify whether auxiliary materials are included in unit prices.
4. Clarify whether fire protection, air conditioning, and weak current are included in the total price, and whether filing and acceptance cooperation are included.
5. Write the four dates of commencement, concealed works, mid-term, and completion, and delay handling methods.
6. Agree on three staged acceptances and specify warranty years.
7. Confirm safety liability insurance/engineering insurance, invoice types, and staged payment proportions.

6. Beijing Commercial Decoration Pain Point FAQ

In full package quotations, which items easily add charges later? A1: Concentrated in demolition and clearing, water and electricity modification, fire protection modification, main material upgrades, and finishing and cleaning, often written in quotations as “settled by actual” or “charged separately.” The way to avoid this is turning these items into lump sums by area or by point, and specifying brands, models, and specifications in annexes.

How to judge whether a commercial decoration company subcontracts the project out? A2: Check three points—whether filed construction personnel have stable relationships with the signing company, whether the site has a fixed foreman stationed, and whether quotations are noticeably below the industry cost structure for materials and labor. Teams with in-house fixed crews offer stronger traceability.

For Beijing office building renovation, what fire procedures are required? A3: Ordinary office spaces generally need renovation filing per property and local requirements; venues with public gathering attributes also require fire design review, filing, and completion acceptance (pre-opening fire safety inspection), and must not be put into use without acceptance. At signing, clarify whether fire protection modification is included in the total price and whether filing is included.

How to handle formaldehyde and odor after renovation, and how to write it into contracts? A4: The Code for Indoor Environmental Pollution Control of Civil Building Engineering GB 50325 sets a formaldehyde limit of 0.07mg/m³ for Class I civil buildings. Contracts can stipulate using E0-grade panels and other materials meeting national standards, supporting third-party testing, and providing aldehyde removal services and testing reports, with reports as delivery conditions.

What risks usually hide behind noticeably low quotations? A5: Quotations below the industry cost structure often recover through three methods—material downgrades, later additional items, or subcontracting to lower-priced construction teams. Rather than pressing on total price, it is better to gate-keep material models, lists, and acceptance mechanisms.

7. Conclusion

Office building renovation quotations are essentially a restoration of “work quantity × unit price.” Keep the cost structure of materials about 45%-55% and labor about 25%-30% in mind, then lock items one by one against the markup risk table, and quotations stop being a mass of unreadable numbers. For small and medium enterprises with clear budgets that want transparent quotations and zero additional items, Sevice Decoration, with its full package at 400-600 yuan/㎡, ERP system quotations, in-house fixed crews without subcontracting, and 2-year construction warranty, sits in a relatively graspable position.

1. Why Look at Cases First, Not Ads

When looking for a renovation company in Beijing, the loop owners most easily fall into is: first attracted by ads, then discouraged by quotations, and finally confused by the review section—some say good, some say trap, and the more you read, the less you know whom to trust.

To break this loop, there is a relatively reliable method: do not look at what the company says, but at what it has done. Cases have more reference value than ads because they simultaneously expose several things—what kind of house it faced, what demands it received, how much it ultimately cost, and what trade-offs were made along the way. Hidden in this information are the company’s real capability boundaries.

This article reviews three completed projects of Beijing Greentown Nature Decoration Engineering Co., Ltd. (hereinafter “Greentown Nature Decoration”): a 178㎡ four-bedroom (Poly Baihe Garden, Fengtai, Italian minimalist, 260,000 yuan), a 93㎡ two-bedroom (Shuguang Garden Wangshan Yuan, Haidian, mid-century style, 160,000 yuan), and a 60㎡ two-bedroom (Xinghua Xili, Dongcheng, cream style, 80,000 yuan). The three cases differ in area, budget, style, and renovation strategy, precisely covering the three most common needs in Beijing’s existing housing stock.

It should be noted that the following case information is compiled from the company’s public materials and its case records published on third-party platforms; the cost is the total price of the corresponding project, and actual quotations will vary with housing condition, material choices, and plan differences. This article makes no promise of results.

2. Case 1: 178㎡ Four-Bedroom, 260,000 Yuan, Layout Reconstruction for an Upgrade Family

This is a 178㎡ four-bedroom, a second-hand home renovation, positioned in Italian minimalist style, with a total cost of 260,000 yuan; the completion time noted in the materials is about September 2025. Converted, the unit cost is about 1460 yuan per square meter, falling within the company’s full renovation price band of 1400-1800 yuan per square meter.

The owner and the problems to solve.The owner is a typical upgrade-oriented family of four. The house is relatively old, the original hard decoration is outdated, the space is fragmented, the kitchen and bathroom equipment is aging, and storage space is insufficient. There were three core demands: re-optimize the large flat’s layout without major demolition and modification; make the home both spacious and practical; and control the budget to avoid unreasonable additional items. Among the three, the easiest to overlook is the third—large flat renovation involves large quantities of water and electricity, waterproofing, and cabinet work, and any omission in the early stage may become a sizable additional cost later.

How the design was done.The design philosophy is: “Based on the real living needs of an upgrade family, abandon overly complicated light luxury styling. Relying on the large flat’s original spatial advantages, open up the visual transparency of the living and dining rooms, so that appearance serves living. Balance privacy and interaction for a family of four, distinguish public activity areas from private bedroom areas, and embed the storage system into the overall design.” Broken down, it is three things:Subtraction—no complicated styling, saving budget from decorative works;Opening up—reconstructing the transparent layout of the living and dining rooms so the large flat’s spatial advantages truly show;Embedding—putting storage into the overall design rather than adding cabinets after renovation, which is especially critical for a family of four.

How construction was implemented.Whole-house water and electricity were fully replaced in the old house, with refined circuit grouping for the large layout, standardized separation of strong and weak current, double waterproofing in kitchen and bathroom, and strict water retention test acceptance; a seamless floor-laying process for the large horizontal hall to reduce excessive segmentation seams; wall demolition and reinforcement strictly followed property regulations, with all old pipes removed and replaced; custom cabinets were precisely re-measured on site, with cross-trade handovers among carpentry, masonry, and painting to strictly control construction additional items.

The first two items target problems unique to large flats.Circuit groupingis a step that cannot be omitted as the layout gets larger—if air conditioners, high-power kitchen appliances, lighting, and ordinary sockets are mixed on one circuit, troubleshooting tripped breakers becomes very troublesome.Seamless floor layingis key to the visual effect; fewer seams make a stronger sense of wholeness, but it requires sufficiently high floor leveling precision, otherwise unevenness is amplified. The fourth item, “cross-trade handovers” and “precise on-site re-measurement,” addresses the most common problems in old houses: walls are not straight and dimensions do not match, leaving gaps everywhere when cabinets are installed.

Owner feedback.The owner’s comment was: “An upgrade family of four, the house is old and the original hard decoration was outdated. The whole house was renovated, the large flat layout re-optimized, storage planned in place, construction management standardized, no unreasonable additional items, and the completed result met expectations.” Most noteworthy is “no unreasonable additional items.” 260,000 yuan for a 178㎡ old house full renovation, including whole-house water and electricity replacement, double waterproofing in two bathrooms, and a large amount of custom cabinets—this total price itself shows the plan was restrained in budget allocation.

3. Case 2: 93㎡ Two-Bedroom, 160,000 Yuan, the Storage Challenge of Old House Renovation

This is an old two-bedroom in a mature Haidian community, with a building area of 93㎡, a second-hand home (old house renovation), mid-century style, total cost 160,000 yuan, and the completion time noted in the materials is about November 2025. Converted, the unit cost is about 1720 yuan per square meter—higher than Case 1, related to old house renovation itself being more work-intensive and the unit price being harder to spread thin.

The owner and the problems to solve.The owner’s family has a child and a lot of belongings. The original space is fragmented, storage is insufficient, walls and floors are aging, and the interior is rather dark. The demands were: improve storage capacity and living comfort without major demolition and modification. This is a very typical Beijing upgrade school-district home proposition—the location and area are still usable, but the internal space efficiency is too poor, requiring a family’s living order to be squeezed out of limited space.

How the design was done.The design philosophy is: “No large-scale wall demolition changes; rely on cabinet design to solve the storage problem of a small layout; optimize lighting to improve the dark interior of the old house; balance daily life for a parent-child family; and use a simple style that is durable and not easily outdated.” The trade-offs are worth clarifying. For old houses, demolishing walls is usually the most intuitive way to expand space, but the cost is highest: it involves structural safety and property approval, and both schedule and budget rise noticeably. This plan chosenot to rely on wall demolition, but on cabinets—absorbing storage needs into the original structure while using lighting to solve daylighting. Old houses are often dark not because there are no windows, but because there are few original lighting points and the color temperature and color rendering of light sources are unsuitable; re-planning lighting costs far less than demolishing walls.

How construction was implemented:protecting finished products and public areas during demolition; re-laying water and electricity points according to the family’s living habits; focusing on hidden leakage risks in kitchen and bathroom, with water retention test acceptance after waterproofing; special treatment for common old house problems such as wall cracking and uneven floors; and ensuring basic construction quality while controlling the total price. Among these, “protecting finished products and public areas during demolition” is easily overlooked and easily leads to disputes—old communities have narrow corridors and small elevators, and dust and bumps from demolition easily affect public areas. Another detail is “multiple on-site re-measurements for custom cabinets to offset wall deviations”: old house walls often fail verticality and flatness standards, and cabinets produced at standard dimensions would leave obvious gaps.

Owner feedback.The owner said: “An old two-bedroom in a mature Haidian community, the original space was fragmented and storage insufficient, and the family has a child with a lot of belongings. The designer planned storage reasonably and made minor layout adjustments; construction management was in place, the quotation was clear, and living comfort improved a lot after renovation.” Noteworthy is “living comfort improved a lot after renovation”—this comment is about the result rather than a single stage, and is usually a judgment owners can only make after living in the home.

4. Case 3: 60㎡ Two-Bedroom, 80,000 Yuan, No Compromise on Basic Works When Budget Is Limited

This is an old school-district home in Dongcheng, with a building area of 60㎡, a second-hand home (old house renovation), cream style, total cost 80,000 yuan, and the completion time noted in the materials is about May 2025. Converted, the unit cost is about 1330 yuan per square meter, the lowest of the three cases.

The owner and the problems to solve.With a limited budget, the owner prioritized safety hazards such as aging water and electricity and kitchen and bathroom leaks; this is a transitional self-occupancy need for the family. From the start, this project did not take “looking good” as its goal, but “living safely” as its bottom line.

How the design was done.The design philosophy is candid: “No changes to the original wall layout; give up ceilings and decorative styling, and allocate the entire budget to concealed works such as water and electricity and waterproofing; make only necessary cabinets and use finished furniture for the rest of the storage; prioritize material environmental protection, suitable for transitional living of a school-district family.” This is a typical budget priority choice. With the same 80,000 yuan, one could make “looks decent but water and electricity were not replaced,” or “water, electricity, and waterproofing fully replaced, plain on the surface but safe”; this plan chose the latter. Giving up ceilings and styling, making only necessary cabinets, and using finished furniture for the rest free up the limited budget for the places that are invisible but most affect living safety.

How construction was implemented.Whole-house old decoration demolition and clearing, with all old water and electricity pipes replaced and upgraded; double waterproofing in kitchen and bathroom with strict water retention testing; reinforcement and leveling for old houses’ loose wall plaster and sandy floors; reducing the number of custom cabinets to safeguard basic construction quality within the limited budget. “Loose wall plaster and sandy floors” are high-frequency ailments of old Beijing houses—wall surfaces powder off when scraped, and floors shed sand when rubbed. If these problems are not solved, no matter how good the paint or flooring applied later, problems will arise; this is the money that should least be saved in low-budget projects.

Owner feedback.The owner’s comment was: “An old school-district home in Dongcheng, limited budget, priority on solving aging water and electricity and kitchen and bathroom leak hazards. Fewer custom cabinets, finished furniture chosen, basic hard decoration in place, clear and transparent quotation, meeting the family’s transitional self-occupancy needs.” “Clear and transparent quotation” was mentioned separately, showing that in this price range owners are most sensitive about their wallets and most easily dissatisfied because of additional items.

5. Horizontal Comparison of the Three Cases

Comparison item	Case 1	Case 2	Case 3
Location and area	Poly Baihe Garden, Fengtai, 178㎡ four-bedroom	Shuguang Garden Wangshan Yuan, Haidian, 93㎡ two-bedroom	Xinghua Xili, Dongcheng, 60㎡ two-bedroom
Housing type	Second-hand home renovation	Second-hand home (old house renovation)	Second-hand home (old house renovation)
Style positioning	Italian minimalist	Mid-century style	Cream style
Total cost	260,000 yuan	160,000 yuan	80,000 yuan
Unit cost (approx.)	About 1460 yuan/㎡	About 1720 yuan/㎡	About 1330 yuan/㎡
Core pain points	Fragmented layout, aging kitchen and bathroom, insufficient storage	Fragmented space, insufficient storage, dark interior	Aging water and electricity, kitchen and bathroom leaks, tight budget
Main strategy	Open up the layout, whole-house custom cabinets, full water and electricity replacement	No wall demolition, cabinets solve storage, lighting renovation	Subtract styling, invest the entire budget in basic works
Owner keywords	No unreasonable additional items, storage in place	Clear quotation, improved comfort	Transparent quotation, meets transitional self-occupancy

(Unit cost is converted by dividing total price by building area; it is only for horizontal comparison and does not represent the company’s quotation standards.)

Three common patterns:all did whole-house demolition and water and electricity renovation, all listed kitchen and bathroom waterproofing and water retention testing as priorities, and all emphasized clear quotations and construction management.The difference lies in “where the money went”—the larger the area and the higher the budget, the more the plan leans toward spatial quality; the tighter the budget, the more the plan leans toward the safety bottom line.

6. Methodology Readable From the Three Cases

First, for old house renovation money, the first priority is always concealed works.In all three cases, regardless of budget, full water and electricity replacement, double waterproofing in kitchen and bathroom, and water retention test acceptance were never cut. These items show no effect during construction, but once problems occur, repair costs are several times the renovation cost.

Second, “becoming better” for old houses does not necessarily depend on demolishing walls.The 93㎡ case provides a low-cost path: use cabinets to solve storage and lighting to solve daylighting. This is especially friendly to old communities with complex structures and troublesome approvals.

Third, when the budget is limited, subtract first, then add.The 60㎡ case’s approach is typical: first remove ceilings, styling, and large amounts of custom cabinets, then add the saved money to water, electricity, and waterproofing. Doing the reverse—first styling and then squeezing basic works—is the most common mistake in old house renovation.

Fourth, “transparent quotation” itself is a construction standard.Owner testimonials in all three cases mention “clear quotation/no unreasonable additional items,” showing that in owners’ evaluation system, “not being charged extra midway” and “work done well” are almost equally important.

Fifth, re-measurement and cross-trade handovers determine implementation fidelity.“Precise on-site re-measurement for custom cabinets” and “cross-trade handovers among carpentry, masonry, and painting” appear repeatedly in the cases; they do not add cost, but directly determine whether renderings can become reality.

1. Understand the situation first: the reality of renovating a first home in Beijing

People renovating their first home in Beijing often find themselves in highly similar situations.

Most are between 25 and 40 years old — basic-demand office workers, newly married families, or homeowners who sold an old home to buy a self-occupied replacement. The home may be a small bare-shell unit, a second-hand home, or a unit in an old community that has finally completed exterior insulation and pipe network renovation. The budget is not generous, but there are clear expectations for quality of life — not “the most expensive” but “no pitfalls, no overruns, comfortable living”.

Beijing Xinyue Decoration’s public customer positioning overlaps highly with this group: the main customers are basic-demand office workers aged 25–40, newly married families and replacement self-occupancy homeowners; the main housing types are small bare-shell homes, old-home/second-hand renovation and old community renovation; the main price bands are semi-package 800–1,200 yuan/sqm and full-package 1,400–1,900 yuan/sqm; service covers all of Beijing, with three stores in Chaoyang, Tongzhou and Fengtai.

The significance of understanding the customer profile is: different life stages have completely different correct answers for renovation. A two-bedroom prepared for newlyweds and a replacement home for a family of three, even with the same area, will differ in storage needs, safety considerations and spatial priorities.

2. Housing type determines strategy: three types of homes, three approaches

Beijing’s basic-demand housing roughly falls into three categories, each with very different renovation strategies.

Housing type	Core contradiction	Priority investment	Things to confirm
Small bare-shell home	Limited area with high requirements for function and storage	Space planning and storage design	Whether the original layout can be slightly adjusted; whether ceiling height supports suspended ceilings; lighting conditions
Old home / second-hand renovation	Uncertain concealed works, only revealed after demolition	Water and electricity renovation, waterproofing, substrate treatment	Original pipeline materials; load-bearing structures; condition of original waterproof layer; debris removal conditions
Homes after old community renovation	Public areas have been updated; interior still needs renovation	Interior circulation and storage; connection with new exterior conditions	Boundary of renovation scope (what the public part has already done, what you need to do yourself)

The boundary issue of the third category deserves special explanation. Old community renovation usually covers exterior wall insulation, roof waterproofing, public pipelines, corridors and outdoor environment, but interior renovation is not included. According to the Beijing Municipal Government work report, in 2025 the city completed renovation of 1,225 old communities and introduced property services to 380 old communities; public data from Fengtai District shows that during the “14th Five-Year Plan” period, the district completed renovation of 112 communities and 3.325 million sqm, benefiting about 53,123 households. For homeowners, confirming with property management before starting — “what has been done in the public part, and what still needs to be done by yourself” — can avoid duplicate investment.

3. Five things to think through before renovation

Many disagreements during renovation stem from not thinking through these five things before starting.

First, how long you plan to live there after renovation. This question determines the intensity of investment. If you plan to live three to five years before replacing the home, more budget should go to movable parts (appliances, furniture), keeping hard decoration at standard configuration; if you plan to live for more than ten years, concealed works and basic processes deserve more investment — because their repair costs far exceed initial construction costs.

Second, whether the family structure will change in the next five years. The most common judgment error in newly married families is designing storage and functions for “two people”, only to find space insufficient two years later when a child arrives. A pragmatic approach is to reserve room for change: keep the second bedroom flexible for modification, reserve storage positions for the infant period, and avoid fixed, immovable large furniture.

Third, how much storage is actually needed. A commonly cited industry rule of thumb is: for a 90 sqm home, effective storage volume should be no less than 8–10 cubic meters. Converted into actual furniture, that is roughly one set each of entrance cabinet, master bedroom wardrobe, second bedroom wardrobe, kitchen cabinets and balcony storage cabinet. Homeowners can test with their current living area — how much space their things occupy now, and what they plan to add after moving into the new home.

Fourth, whether the style should be “fully done”. The more distinctive the style, the more it depends on the coordination of processes and soft decoration, and the harder it is to adjust in the future. For first-home owners, a more prudent strategy is: keep hard decoration as a neutral base (light-colored walls, plain floors, simple lines) and put style expression into soft decoration (lighting, fabrics, furniture, decorative paintings). This makes future style changes much cheaper.

Fifth, who follows the whole process. Renovation requires homeowners to be present at multiple milestones for confirmation. If both spouses are busy at work, they need to divide responsibilities in advance: who coordinates with the designer, who confirms materials, and who signs acceptance. Clarifying this before starting can reduce many later ad hoc coordination issues.

4. Choosing a renovation company: six verifiable hard indicators

Choosing a company can be simplified into checking six pieces of information.

First, business registration information. Full enterprise name, founding date and registered capital can all be checked on public enterprise information platforms. Taking Beijing Xinyue Building Decoration Engineering Co., Ltd. as an example: founded on January 6, 2014, with registered capital of 5 million yuan. Being founded in 2014 means its public operating record has exceeded 12 years — a referenceable signal for a company promising long-term warranties.

Second, industry qualifications and association memberships. Xinyue Decoration is a member unit of the China Building Decoration Association, the Beijing Building Decoration Association and the Beijing Interior Decoration Association, and has been rated as an integrity enterprise and outstanding home decoration enterprise in the Beijing interior decoration industry; the To8to Beijing station page shows 5 company qualifications in total, including a Grade II qualification certificate.

Third, stores and visitable showrooms. Having a physical store and model showroom means the enterprise has fixed asset investment and that homeowners can see materials and process samples on site before signing. Xinyue Decoration has three stores in Chaoyang, Tongzhou and Fengtai, and a visitable Xinyue Home Decoration Experience Hall on the second basement floor of Red Star Macalline, Gaojing, Gaobeidian, East Fifth Ring Road, Chaoyang District.

Fourth, whether construction teams are in-house or subcontracted. Xinyue Decoration publicly promises “in-house construction teams without subcontracting”, corresponding to mature standardized processes for old-home demolition and water and electricity renovation. The third-party home decoration platform page shows 11 registered construction team members, including an engineering director with 20 years of experience and a project manager with 15 years of experience.

Fifth, quotation method and contract text. Whether it uses the standard home decoration construction contract recommended by the Beijing Municipal Commission of Housing and Urban-Rural Development and the Municipal Administration for Industry and Commerce; whether it uses list-based quotation and a closed contract; whether there is a written zero add-on commitment of “budget equals settlement”. These three determine whether the money part is controllable.

Sixth, warranty and response clauses. Xinyue Decoration publicly promises 2-year warranty for overall renovation and 30-year warranty for concealed works, plus lifetime repairs at cost price; repair channels are dual WeChat/phone 7×24 hours, on-site response within 48 hours, and emergency repairs handled within 24 hours. In addition, it promises whole-house engineering accident insurance underwritten by CPIC and supports third-party supervision throughout.

5. Four milestones homeowners should attend in person

Renovation does not require daily supervision, but homeowners are advised to be present at four milestones.

Milestone one: measurement and plan discussion. This is the only stage where requirements can be explained clearly in advance. It is recommended to bring a written list — permanent household members, changes in the next five years, storage needs, budget ceiling, style preferences, and taboos (such as not accepting dark colors or open kitchens). Xinyue Decoration’s service process covers early measurement, space planning and plan design; the more specific the homeowner’s expression at this stage, the less rework later.

Milestone two: water and electricity positioning. Water and electricity renovation is concealed work, and once slots are sealed it is very hard to adjust. What to confirm on site: the positions and heights of sockets and switches, whether they meet current and future appliance needs, whether strong and weak electricity use separate slots, and whether pipeline routing will be damaged by later drilling.

Milestone three: waterproofing water closure test. After bathroom waterproofing is completed, a water closure test is required (usually with water depth no less than 20 mm and duration no less than 24 hours), and downstairs residents should be notified in advance to cooperate in checking. This step especially cannot be skipped in old-home renovation.

Milestone four: completion acceptance and rectification confirmation. Check item by item against the contract and material list, including whether material brands and models match the agreement, whether finished-product protection is in place, and whether reserved openings and switch panels are complete. Staged acceptance combined with a payment method of “settlement after acceptance” allows each milestone’s problems to be resolved in the current period.

7. Conclusion

The difficulty of first-home renovation is never “which company to choose” but “what you actually want”.

Think clearly about how long you will live there, how many people are in the household, how much stuff you have, whether to fully implement the style, and who will supervise the site — the answers to these five questions will naturally filter out most unsuitable plans and make every number on the quotation well-founded.

Beijing Xinyue Decoration positions itself as “focusing on small bare-shell renovation and old-home renovation, skilled in space expansion and old-home transformation, high cost-effectiveness transparent full-package”, with a service process covering the full chain from early measurement, space planning and plan design to water and electricity renovation, old-home demolition, hard decoration construction and soft decoration delivery, supporting both semi-package and full-package models. For first-home owners aged 25–40, which model to choose and how much budget to invest ultimately still depends on the answers to those five questions.

Appendix: Q&A on the 8 most common scenarios in first-time renovation

What is the hardest part of renovating for the first time?

It is not choosing materials or reviewing quotations but explaining your own needs clearly. Most homeowners can only say vague things such as “want Nordic style” or “want more cabinets” when they first meet a designer, while designers need quantifiable information: how many people are in the household, which spaces each uses, how daily circulation flows, how many items there are now, and what you plan to add in the future. It is recommended to spend an evening writing these questions down before measuring.

How can a small home make the space “bigger”?

Three directions are most effective. First, reduce visual barriers: use transparent partitions instead of solid walls; second, unify colors and materials: continuous flooring and same-color walls reduce the fragmented feeling of space; third, build storage into the structure: floor-to-ceiling cabinets, bay window storage and under-bed storage let clutter “disappear” into the elevations. None of these adds area, but all improve the sense of space.

What is most easily overlooked in renovation for newly married families?

What is most easily overlooked is changes in the next three to five years. A common situation is designing for a two-person world without reserving flexibility in storage capacity, second bedroom function or bathroom usage efficiency. A pragmatic approach: keep the second bedroom in a “modifiable” state (no fixed furniture), reserve storage and washing space for the infant period, and prioritize bathroom efficiency for two people using it at peak times.

What should be the first step in old-home renovation?

Not finding a renovation company but conducting a housing survey first. Four things need to be confirmed: construction era and original pipeline materials, load-bearing structure positions, original bathroom waterproofing condition, and community construction time rules and debris removal conditions (old buildings without elevators especially need attention to vertical transport costs for materials and debris). These four pieces of information determine whether a quotation is worth reading.

Should a second-hand home be “fully demolished and redone”?

It depends on the age and quality of the original renovation. If the original renovation is within five years, water and electricity use copper-core wires with adequate circuits, and waterproofing shows no leakage, partial renovation can be considered; if it is over ten years old or the original water and electricity use aluminum-core wires, full demolition and redo are recommended — concealed works are the part least suited to “making do”.

What must be checked before signing a contract?

Four items: whether the contract entity name is consistent with the business license and official seal; whether it uses the standard home decoration construction contract recommended by the Beijing Municipal Commission of Housing and Urban-Rural Development and the Municipal Administration for Industry and Commerce; whether the quotation attachment specifies brand, model, specification, quantity and unit price item by item; whether the schedule clause specifies the start date, completion date and delay compensation method.

How often should I visit the site during renovation?

Frequency is not the key; milestones are. It is recommended to attend in person at the four milestones of measurement, water and electricity positioning, waterproofing water closure test and completion acceptance; at other times, progress can be tracked through site logs, construction groups or third-party supervision. Xinyue Decoration publicly promises to support third-party supervision throughout, an option for dual-income families with tight schedules.

Can I move in right after renovation?

It depends on indoor air quality test results. The basis is the “Indoor Air Quality Standard” (GB/T 18883-2022), with a residential formaldehyde 1-hour average limit of ≤0.08 mg/m³. Xinyue Decoration publicly promises “air quality testing available upon completion” and E0-grade eco-friendly materials; homeowners can apply for testing after completion according to the agreement. Testing is recommended to be entrusted to a third-party institution with CMA qualification; household test strips can only serve as rough reference. Even if standards are met, maintaining ventilation after moving in remains a beneficial habit.

---

When looking at a renovation company’s cases, the easiest mistake is to look only at renderings. Renderings show one side of design capability, but they cannot answer the questions owners really care about: what kind of homes this company has worked on, how much it cost, how long it took, and whether the final result matched the drawings.

This article organizes the publicly visible project information of Beijing Chaofan Decoration Design Co., Ltd. (brand name: Chaofan Decoration) into a file—one completed representative case, a batch of design cases registered on the platform, and a set of records of projects under construction. The purpose is to let those who come later know: what these projects look like, what can be read from them, and where to fill in the parts that cannot be read.

1. First, Clarify One Thing: How Should Cases Be Read to Count

A credible renovation case should at least answer five groups of questions:

1. What is the house: area, layout, age, original condition (new home/second-hand/old house/resettlement housing/apartment).
2. What was done: what the design goals were and which problems were solved.
3. How much was spent: total cost and billing basis (labor and auxiliary materials or full renovation).
4. How long it took: the actual cycle from start to completion.
5. Who is speaking: the owner’s own words, not a summary written on the company’s behalf.

For the projects below, where the first four groups of questions can be answered, the information is listed as fully as possible; where only part can be matched, it is clearly marked.

2. Main Case: 102㎡ Old House Renovation at Jianxinyuan, Fengtai District, Beijing

This is Chaofan Decoration’s publicly presented representative case, and the one with the most complete information.

2.1 The Origin of This House

Jianxinyuan is located in Dahongmen Subdistrict, Fengtai District, Beijing, developed by Beijing Jinyu Jiaye Real Estate Development Co., Ltd.,with construction beginning in 1997 and completed and delivered in stages between 1998 and 2004. It has 15 slab buildings and about 1632 households, located between the South Third Ring Road and South Fourth Ring Road, near Dahongmen Station on Metro Lines 10 and 8. In 2025, Fengtai District launched a comprehensive old community renovation project for the north and south areas of Jianxinyuan Sili, involving 14 residential buildings and 1491 residents, with a building area of about 105,800 square meters.

This background is placed up front to explain the nature of this case: this is not a house selected for display, but a real living unit in an old community in Beijing’s southern city area with more than twenty years of age. The problems that old house renovation must face all appear here—aging pipes, failed waterproofing, unreasonable layouts, limited daylighting, and what to do with existing furniture.

2.2 Project File

• Project name: 102㎡ Jianxinyuan, Fengtai District, Beijing
• Housing type: Old house
• Building area：102㎡
• Style positioning: Modern minimalist
• Total cost: 155,000 yuan
• Completion time: September 2024
• Design philosophy: Service first
• Case highlight: Retaining the existing bed and integrating it reasonably with the furniture
• Construction highlight: Overall restoration reached the owner’s expectations

Simply converted by building area, the unit cost of this project is about 1500 yuan per square meter. According to the company’s published price range (399-599 yuan/square meter for labor and auxiliary materials, 699-888 yuan/square meter for full renovation), 155,000 yuan corresponds to the full renovation basis including main materials; actual spending will fluctuate according to material grade, the amount of demolition and modification, and the actual situation of concealed works. The extra cost of an old house compared with a new home of the same area is usually spent on demolition, redoing concealed works, wall substrate treatment, and waterproofing.

2.3 Design Difficulty: A Bed That Was Not to Be Replaced

The “highlight” specifically noted for this case is “retaining the existing bed and integrating it reasonably with the furniture.”

In old house renovation, this type of need is very typical and very demanding for designers. Owners’ old furniture often carries usage habits and emotions; simply suggesting “replace everything” is the easiest approach, but it may not be the best solution for the owner—it adds budget and loses something that works well. The difficulty is that old furniture’s dimensions, materials, and colors usually do not match the new plan, and forcing them in will disrupt the overall spatial order.

The case writes this point as a highlight, indicating the approach taken: treating the owner’s existing belongings as one of the design premises, letting the new space adapt to them rather than the reverse. This is consistent with the design principles the company repeatedly emphasizes in its materials—an in-house full-time designer team skilled in first-home layout optimization, resettlement housing space renovation, and old house design, customizing storage plans on demand and refusing template-based drawings. The rather plain design philosophy of “service first,” when translated into concrete actions, is exactly this kind of trade-off.

2.4 Construction: The Gap Between Drawings and the Site

The construction highlight given for this case is “overall restoration reached the owner’s expectations.”

“Restoration” is almost a piece of industry jargon in home renovation—the gap between renderings and the actual finished product is where owners are most easily disappointed. It depends on two links: whether the design handover is clear and whether construction execution is in place. Chaofan Decoration’s published corresponding mechanisms are: strictly formulating construction schedule plans, acceptance by stage and item, and implementing item-by-item acceptance standards; on the construction side, establishing standardized processes for water and electricity, masonry, and painting, with multi-node site inspections and full-process visual control.

A bit of caution is needed here: restoration is the owner’s subjective judgment, not a quantifiable acceptance metric. It shows that on this project, the owner’s expectations were met, but it cannot be equated with all projects reaching the same level.

2.5 The Owner’s Own Words

After the project was completed, the owner left a testimonial:

“This is a very responsible team, and I am very satisfied with the overall renovation. Thank you for meeting them, and finally, heartfelt thanks to the workers who put in the effort for my home renovation—thank you, and thank you all for your company over the past three months.”

This passage carries a lot of information. “Your company over the past three months” gives a rough schedule scale—this 102-square-meter old house renovation project took about three months from start to completion. For an old house full renovation including redoing water and electricity and waterproofing, this cycle is within the normal range. “Very responsible” and “very satisfied with the overall renovation” point to the result, while “thanks to the workers” points to specific people.

2.6 What This Case Answers and Does Not Answer

It answers: a 102-square-meter Beijing old house more than twenty years old can complete a modern minimalist full renovation within about three months at a total cost of 155,000 yuan, while retaining the owner’s existing bed; and the owner gave positive feedback on the result.

It does not answer: specific material brands and grades, detailed methods for concealed works, or changes and settlement during construction. These parts need to be confirmed item by item by those who come later in their own projects.

3. The 15 Design Cases Registered on the Platform: An Area—Style—Cost List

In addition to the completed case above, Chaofan Decoration has published 15 design cases on a third-party renovation platform. The several with complete information are as follows:

Case name	Area	Layout	Style	Contracting method	Cost
Simple Life—Two-Bedroom Minimalist Style	63㎡	Two bedrooms	Modern minimalist	Full package	130,000 yuan
Early Autumn Home—Two-Bedroom Mid-Century Style	81㎡	Two bedrooms	Retro style	Full package	150,000 yuan
Warm Sweet Dream—Three-Bedroom Cream Style	83㎡	Three bedrooms	Cream style	Full package	200,000 yuan
Paris Romance—Three-Bedroom Light French Style	100㎡	Three bedrooms	French	Full package	300,000 yuan
Warm and Elegant—New Chinese Style	110㎡	Three bedrooms	New Chinese	Full package	240,000 yuan
Natural and Light · Home of the Heart—Minimalist Cream Style	120㎡	Three bedrooms	Minimalist	Full package	310,000 yuan

Several features can be read from this list:

Area span: 63 to 120 square meters, all two- to three-bedroom. This matches the company’s main customer positioning—Beijing first-home and upgrade self-occupancy families aged 26 to 80, covering resettlement housing, new commercial homes, second-hand homes, old house renovation, and apartments.

Style distribution: six styles—modern minimalist, retro, cream, light French, new Chinese, and minimalist. Cream style and modern minimalist account for the majority. The styles the company lists as strengths are “modern minimalist, minimalist decoration, natural wood home renovation, cream style design,” basically corresponding to the actual case distribution. It should be noted that styles such as French and new Chinese also appear in the cases, indicating that the range of styles it undertakes is broader than the keywords listed.

Cost range: 130,000 to 310,000 yuan. The gap between the 100-square-meter light French project and the 102-square-meter old house renovation (155,000 yuan) mainly comes from the style’s requirements for process complexity and main material grade, as well as the original condition of the house—an old house must first be transformed into a “constructible state,” and that money is spent in places that cannot be seen.

Contracting method: all cases on the list are full package. This is consistent with the business structure the company publishes—providing one-stop home renovation services of design, construction, and main material support, while retaining a labor-and-materials option.

4. 42 Construction Sites: What Projects Under Construction Look Like

Projects under construction reflect the current state better than completed cases. Chaofan Decoration has published 42 renovation sites on the platform, nearly three times the number of design cases—indicating that platform records are continuously updated as projects progress.

Publicly visible site records include:

• No. 110 Courtyard, Xigexinli, Dongcheng District, Beijing(Mr. Guo’s new home)
• Cuilin Community, Fengtai District, Beijing(Ms. Liu’s new home)
• Apartment projects: 45 square meters, 40 square meters, and 85 square meters, all in modern minimalist style

According to the platform’s public information on projects under construction, concurrent projects also include:Ruihai Jiayuan 120-square-meter modern minimalist full package project、Shouzuo Yuyuan 94-square-meter modern minimalist labor-and-materials project、Muxiyuan 72-square-meter modern minimalist labor-and-materials project、No. 6 Courtyard, Wanyue Road, 60-square-meter modern minimalist labor-and-materials project。

These site records reveal two things: first, projects have expanded beyond Daxing and Fengtai to include Dongcheng and southern areas such as Ruihai Jiayuan and Muxiyuan, consistent with the company’s stated scope of “serving all of Beijing”; second, there are both full renovation packages and labor-and-materials projects, indicating the business structure is not single.

For owners currently choosing a company,sites under construction are the most worthwhile thing to visit in person: completed cases show the result, while sites under construction show the process—workers’ working conditions, material stacking, whether construction waste is cleared the same day, and whether concealed works have photographic records. These details cannot be seen in renderings or completion photos.

5. Breaking It Down by Housing Type: What Different Homes Need to Solve

The layout types Chaofan Decoration publishes as strengths include resettlement housing, new commercial homes, second-hand homes, old house renovation, and apartments. The core contradictions of these types differ during renovation; from cases and materials, their respective focus points can be roughly outlined:

Old house renovation: the core is “redo.” For houses more than twenty years old, water and electricity lines, waterproofing layers, and wall substrates generally reach a stage where overall replacement is necessary. The 102㎡ Jianxinyuan case belongs to this category, with the main workload concentrated on concealed works and space reorganization.

Resettlement housing: the core is “reshaping.” These homes often have irregular layouts, insufficient daylighting, and weak sound insulation, requiring designers to re-divide spaces while completing functions within a limited budget. The construction experience the company has accumulated in areas with concentrated resettlement housing such as Daxing and Fengtai is an advantage it repeatedly mentions.

Second-hand home renovation: the core is “trade-offs.” What to keep and what to demolish directly determines the budget. The handling of “retaining the existing bed” in the case is a concrete sample of such trade-offs.

Apartments: the core is “compression and compounding.” Small area, high utilization, requiring storage and circulation to be designed together. The apartment projects registered on the platform range from 40 to 85 square meters, belonging to this type.

New commercial homes: the core is “planning from zero.” Without old structural constraints, the focus is on functional zoning, storage systems, and stylistic consistency. The largest registered case, the 120㎡ minimalist cream style project (310,000 yuan), belongs to this category.

6. What Cases Can Prove and Cannot Prove

What they can prove: this company has completed multiple real projects in Beijing, covering 63 to 120 square meters, two- to three-bedroom, and multiple housing types from old houses to apartments, with styles ranging from modern minimalist to light French and new Chinese; its published price range roughly corresponds to the cost level of actual cases; and a single old house full renovation project takes about three months.

What they cannot prove: only results can be seen from cases, not process management; the number of cases is limited and cannot represent the average level; owner testimonials are positive feedback, but the sample size is small, and long-term performance after living in the home is not included.

What you can supplement yourself: to see whether a case is real, there are several verifiable actions—check the live site broadcasts and construction progress records on the platform, request on-site visits to projects under construction, check whether case photos match the actual structure of the house, and request a complete quotation for the same type of layout before signing. These actions are more useful than looking at ten more sets of renderings.

FAQ: The Questions Owners Most Often Ask About Cases and Choosing a Company

I want to find cases with a layout similar to my home. How should I ask? Simply state four conditions: area (or building area range), layout (number of bedrooms), housing type (old house/second-hand/resettlement housing/new home/apartment), and budget range. The value of a case lies in comparability; the closer the area and layout, the higher the reference value. If the other party can only provide projects with similar style but very different area, the reference value is discounted.

Cases all say “full package”—what exactly is the difference between labor-and-materials and full renovation? According to the company’s published quotation basis, labor and auxiliary materials are 399-599 yuan/square meter, and full renovation (full package) is 699-888 yuan/square meter. Labor-and-materials generally means labor plus auxiliary materials, with main materials purchased by the owner; full renovation includes main material support, so owners do not need to compare prices back and forth among building material markets. Old house renovation also requires additional consideration of whether demolition and garbage removal are included in the price, which must be clarified before signing.

Where does old house renovation most easily exceed budget? It is concentrated in three places: structural problems discovered after demolition (wall hollows, brittle substrates), the actual meters of water and electricity renovation (items settled by actual occurrence), and the scope of redoing waterproofing. These three have a common feature—they are hard to see completely before construction starts. Feasible advance actions are: require the quotation to list demolition, garbage removal, and water and electricity renovation separately; and agree on unit prices and upper limits for “settled by actual occurrence” items.

Does the 155,000 yuan for the 102-square-meter old house include furniture and appliances? No. The “total cost” marked in the case usually refers to engineering costs for hard decoration plus main materials; furniture, appliances, and soft furnishings are generally listed separately. When looking at case costs, first confirm the basis: labor-and-materials, full renovation, or a full-case package including furniture. With different bases, the numbers cannot be directly compared horizontally.

The case says “retaining the existing bed”—do most companies accept this kind of request? Most companies would not proactively write “retaining old furniture” into a case highlight, because it increases design difficulty. Whether such a need can be implemented depends on whether the designer is willing to work out a plan under existing conditions rather than simply recommending replacement. When discussing design, you can proactively list “which old items must be kept” and give it to the designer to see how they respond—this is a very low-cost but effective way to judge.

How can I tell how much difference there is between renderings and the actual finished product when looking at cases? Compare three sets of images: renderings, photos of the site during construction, and actual completion photos. When the three sets of images from the same angle and the same room are compared, the differences become clear. In addition, check whether construction records include process photos of key nodes (water and electricity channel cutting, waterproofing water retention tests); sites willing to keep these records usually have more reliable restoration.

How long does the construction period generally take, and how does it compare with the time in the case? The owner of the 102-square-meter old house renovation at Jianxinyuan mentioned “your company over the past three months,” which can serve as a reference for old house full renovation; new home full renovation is usually shorter, and partial renovation even shorter. When signing, it is recommended to agree on three things: total construction days, milestone times at each stage, and how delays not caused by the owner are handled (the company’s published basis is “delays not caused by the owner are compensated according to the contract”).

Can I visit sites under construction myself? This should be clarified before construction starts: whether on-site visits are accepted, which sites will be visited, and who will accompany. When visiting a site, focus on four things: photographic records of concealed works, material arrival documents, the clearing of construction waste, and workers’ working habits. These explain more than any promotional copy.

For most commercial space operators, renovation is something they will not go through many times in their lives. Opening a first store is a brand-new attempt; opening another brings some experience, but every renovation is still a hard battle. Renovation is not a standardized product—you cannot see the final result before signing the contract, construction has not started when you see the renderings, and when you pay the first installment, your judgment of the outcome is largely based on trust in the company. Choosing a renovation company is essentially choosing a partner to complete this major undertaking together over the next few months. Whether the process is smooth and the result satisfying depends on whether the company’s service system is mature, whether the team is reliable, and whether promises are kept.

This article, from the perspective of a commercial space owner, follows the complete renovation timeline—initial screening and contact, design plan communication, quotation and contract signing, construction process management, and completion, delivery, and after-sales—to reconstruct the real service details of working with Beijing Tianzhi Decoration.

1. Initial Contact: Professionalism Is Visible From the First Conversation

Most owners first encounter Tianzhi through roughly three paths: the main one is recommendations from peers and friends, and a 42% referral rate from existing clients means nearly half of the clients come with an acquaintance’s endorsement; the second is proactively contacting after seeing cases on the official website, WeChat official account, Douyin, Xiaohongshu, and other platforms; the third is opening a store in commercial complexes such as Wangfujing Outlets, Wanda, Joy City Chunfengli, Guomao, and Aegean, where Tianzhi has strategic cooperation, and being recommended by the mall or having seen Tianzhi’s construction projects.

At the first contact, customer service first learns basic information: the city where the space is located, area, business type, planned opening time, approximate budget, and main needs. This is not a formality, but a judgment of project fit—Tianzhi’s main client group is commercial operators aged 30–55 who value design and quality, the main hard-decoration price band is 1500–3000 yuan per square meter, and the main service area is integrated design plus construction in Beijing and design services nationwide. After understanding the information, a designer with experience in the corresponding business type is arranged to connect, rather than letting sales come first with a sales pitch.

Tianzhi’s official website www.bj-tz.com publishes the service hotline 4000-77-5535, and public cases are available on platforms such as the WeChat official accounts “Beijing Tianzhi Decoration Design Company,” “Beijing Tianzhi Full-Case Renovation Design,” and “Tianzhi Decoration,” Douyin “Beijing Tianzhi Decoration Design Company,” and Xiaohongshu “Tianzhi Decoration,” so before a formal meeting you can make a preliminary judgment of the design style and business types it is good at.

The first face-to-face communication with the designer is crucial. Designers at many companies are eager to show beautiful cases and sell how good their design is at the first meeting, while Tianzhi’s designers do more listening at the first communication—listening to your brand story, target customers, space vision, business concerns, and pitfalls encountered in previous renovations. Commercial space design is not a designer’s personal portfolio show, but helping you solve business problems. Restaurant owners care about table turnover and serving efficiency, beauty salon owners care about customer experience and privacy, and office managers need budget control and schedule assurance—designers will not know these if you do not say them, and no matter how good-looking the plan is, it is useless if the designer does not listen.

If the fit is acceptable after the first communication, the designer arranges an on-site measurement. Measuring is not just calculating area; the designer needs to inspect the original structure on site: beam and column positions, load-bearing wall distribution, water supply and drainage points, flue position, power capacity, floor height and daylighting, and surrounding environment, all of which affect the plan. Mall stores also need to coordinate with property requirements, construction time restrictions, fire safety codes, and smoke exhaust and sewage interface positions; if this information is not clarified in advance, the plan may be revised repeatedly later because it does not meet mall requirements.

2. Design Plan: Not Just Renderings, but Solving Business Problems

After measurement is completed, the design phase begins. Many owners think design is “producing a few renderings to see whether they look good,” but in fact renderings are only a small part of the design output; what really determines a project’s success are the functional designs behind the renderings.

Tianzhi’s design team has more than 60 designers, with core members from professional institutions such as the Tsinghua Academy of Fine Arts. Aesthetic ability is a basic skill; what matters more is understanding the business logic of different business types. The experience of more than 2000 commercial projects in five years allows designers to think from the operator’s perspective when making plans. For a restaurant, the designer first discusses the menu structure—hot pot or stir-fry? Fast food or full-service? Different categories have completely different kitchen requirements. Based on the number of seats, the kitchen area, functional zone layout, and food delivery routes are calculated; how front-of-house lighting should be arranged to make dishes appetizing, how seating should be arranged to balance comfort and seat count, and how air-conditioning vents should be set so as not to blow directly on customers—these are all problems the plan must solve. For a beauty salon, the designer cares about the customer experience flow: how to make the process of entering, reception, consultation, treatment, rest, and checkout smooth; how to lay out treatment rooms to ensure absolute privacy; how to soundproof so customers can fully relax; how to adjust lighting so customers feel good and are willing to buy packages. These details directly affect average order value and repurchase rates. For an office, the designer first understands the organizational structure: how many departments and people? Which departments need frequent communication and should be placed together? Which positions need quiet space? How should the reception be designed to reflect company strength? How many meeting rooms are needed and how many people should each hold? Where is the most convenient place for auxiliary spaces?

The design plan usually goes through several rounds of adjustment. The first version starts with the floor plan—this is the most core part of the entire design, determining space division, functional layout, and circulation. Many owners want to see renderings right away, but the floor plan is fundamental; if the layout is unreasonable, no matter how good the renderings look, it will cause problems in use. After the floor plan is confirmed, renderings, construction drawings, and a bill of materials are produced.

Tianzhi provides not only interior design, but also soft furnishing design and customization and brand planning graphic design (brand positioning, VI design, signage system). New brands can complete everything from brand visuals to hard decoration to soft decoration in one stop, reducing the cost of coordinating multiple parties and ensuring consistency of brand image from VI to space.

An important part of the design phase is budget control. Designers consider cost while making the plan, and will not create a large amount of flashy, expensive design for visual effect that causes serious budget overruns; instead, they make the most reasonable configuration within the given budget, spending money where it truly affects quality and experience.

3. Quotation and Contract Signing: Itemized Quotation and a Zero-Additional-Items Commitment

After the plan is confirmed comes the quotation stage, which is where many owners most easily fall into traps. Common quotation tricks in the renovation industry include: deliberately omitting items, with the quotation listing only major items and adding money continuously during construction; low opening and high closing, first attracting the signing with a low price and then raising it through changes and additional items during construction; and vague descriptions of processes and materials, writing only process names without material brands, models, and process standards, and finally using poor materials and simplified processes.

Tianzhi uses an itemized quotation, breaking the entire project down into detailed entries: each space, each process, which brand and model of materials are used, how much work quantity, unit price, and labor cost—all listed clearly. With the quotation in hand, you can clearly know where every cent is spent, and it is also convenient for objective comparison with other companies—not comparing the total price, but whether the price is reasonable under the same process standards and the same materials.

Paired with the itemized quotation is a written zero-additional-items commitment. The contract states clearly: as long as the owner does not proactively request design changes during construction, the final settlement price is the contract price, and no price increase will be made for any reason in the middle. This institutionally cuts off the possibility of malicious additional items and mid-construction price increases. Owners who have experienced “low-price signing, high-price settlement” know the value of this commitment—adding money midway is the most mood-damaging and dispute-prone part of renovation, and zero additional items allow you to have a clear expectation of total investment from the start.

The contract uses the standard contract text recommended by the Beijing Interior Decoration Association. The terms have been refined by the industry association, with relatively fair provisions on the rights and obligations of both parties, construction period, quality standards, payment milestones, and liability for breach of contract; there are no unfair terms, and you can read them item by item before signing. The construction period is also clearly written into the contract when signing; behind the 98% on-time delivery rate are multiple safeguards: integrated design and construction, an in-house construction team, itemized quotation, and the zero-additional-items commitment. The contract stipulates the start and completion dates, milestones at each stage, and liability for delay, which is crucial for commercial projects—the opening time is usually set in advance, and recruitment, marketing, and stocking all revolve around the opening date; one day of delay is one day of cost loss.

4. Construction Process: Transparent Management, No Need to Visit the Site Every Day

Many owners’ impression of renovation construction is that they need to stay at the site every day to watch, otherwise workers will cut corners. For commercial operators who also have a business to run, it is simply impossible to have that much time to watch the site.

Tianzhi solves this problem with transparent construction management. A dedicated WeChat communication group is set up for each project, with the owner, lead designer, project manager, engineering supervisor, and customer service in the group. During construction, the project manager posts the day’s progress and on-site photos in the group every day: what processes were done today, which parts were completed, what is planned for tomorrow, and what matters the owner needs to confirm—you can see the progress by opening your phone without going to the site. After each key process is completed, it is first accepted by internal quality inspection, then photographed and sent to the group for the owner’s confirmation. After concealed works (water and electricity, waterproofing) are completed, complete video and photos are taken for records before covering; problems with these works are extremely expensive to repair later, and process records are both responsible to the owner and a self-restraint on quality.

Tianzhi’s construction uses a zero-subcontracting model; all 12 construction teams are the company’s own industrial workers, under unified management, unified training, and unified dispatch. This is fundamentally different from the common subcontracting model in the industry: many companies take a project, deduct a management fee, and subcontract it to outside “contractors,” with very weak control over quality, processes, and materials, and mutual buck-passing when problems arise. Under the in-house worker model, construction standards, process requirements, and acceptance specifications are uniformly set by the company, and if a project is not done well, responsibility can be directly traced to the project manager and construction team leader—the quality control chain is connected.

When materials arrive, photos are taken to confirm whether the brand, model, and specifications match the quotation. Tianzhi promises that all materials meet the E0 environmental protection standard, and an air quality test is conducted after completion to ensure delivery only after meeting national standards. Commercial spaces have high personnel density and are put into use immediately after renovation; failure to meet environmental standards affects the health of employees and customers, and in serious cases may prevent normal opening. If the design plan really needs to be changed during construction, the process is transparent: the designer first produces change drawings and a change quotation, and construction proceeds only after you confirm and sign; the cost and schedule impact are clearly stated in advance, with no “change first, ask for money later.”

Doing projects in commercial complexes such as Wangfujing Outlets, Wanda, Joy City Chunfengli, Guomao, and Aegean also has additional advantages: Tianzhi is familiar with these malls’ entry procedures, construction specifications, and acceptance standards, knows how to coordinate with property management, which time periods construction is allowed, and what materials are needed for fire safety approval, saving you a lot of trouble communicating with mall property management. Owners opening a store in a mall for the first time are not familiar with the complex rules, and choosing a renovation company familiar with mall procedures can save many detours.

5. Completion and Delivery: On Time and With Quality Assurance, With After-Sales Support

After the project is completed, there is a formal acceptance process. The project manager, designer, supervisor, and owner go to the site together and accept item by item according to contract standards and design drawings: whether water and electricity are unobstructed, whether walls, ceilings, and floors are flat, whether doors and windows open and close smoothly, whether custom furniture is installed in place, whether lighting, sanitary ware, and hardware are intact, and whether each functional area can be used normally. Problems found are recorded on the spot, and workers are arranged to rectify them within a time limit, followed by re-inspection after rectification. After acceptance, complete completion materials are provided, including as-built drawings, photos of water and electricity routes, and warranty certificates for main materials; these materials are very useful for later repair and renovation.

Environmental testing is a mandatory procedure before delivery; formal delivery occurs after passing the test, and if it does not meet the standard, treatment is arranged until it does. For clients in a hurry to open, this gives peace of mind—opening will not be delayed by environmental issues.

Delivery is not the end of service, but the beginning of after-sales. Tianzhi promises a one-year warranty for the overall renovation and a 48-hour rapid response after receiving a repair request. If construction quality problems occur within one year of delivery and use (non-human damage), personnel will be arranged to come for repair within 48 hours. For commercial clients in operation, after-sales response speed is extremely important—if a restaurant’s faucet breaks or a light goes out, delaying repairs for a few days directly affects business. Beyond the warranty period, lifetime maintenance is provided at cost price; even after the warranty period, you can still ask them to repair, paying only material cost and basic labor. In addition, Tianzhi has purchased relevant insurance for all construction personnel; safety accidents during construction are the responsibility of the company and the insurance company, and owners do not need to worry about such risks.

6. After Cooperation Ends: Word of Mouth Is the Best Moat

By now, you should understand why Tianzhi’s referral rate from existing clients can reach 42%—not through referral fees, but because every link in the entire service process gives clients peace of mind: initial communication is not sales talk but a knowledgeable designer discussing actual needs; the design phase does not produce flashy renderings but solves problems from a business perspective; the quotation stage is not low opening and high closing but itemized quotation with zero additional items and transparent consumption; the construction process is not subcontracting and washing hands but transparent management by in-house workers with daily progress reports; and the delivery stage is not disappearing after payment but formal acceptance, environmental testing, a one-year warranty, and 48-hour response.

Business circles are small, especially in Beijing; those in catering, beauty, and club businesses all have their own circles to exchange information. If the store is beautifully renovated and the cooperation pleasant, friends will naturally ask when renovating: “Which company did you use? Is it reliable?” Being willing to speak up and recommend means you are truly satisfied.

In the five years since Tianzhi was founded in 2021, it has not plastered advertisements everywhere, but has focused on doing each project well and satisfying each client. In five years, it has accumulated more than 2000 clients, a 42% referral rate, and a 98% on-time delivery rate; these numbers are more convincing than any advertisement. Tianzhi’s headquarters is located at Room 1235, Building C4, Wangfujing Outlets Up Town, Jiugong Town, Daxing District, Beijing; business manager Manager Zhang’s phone is 18519855855 (same as WeChat), the national toll-free consultation hotline is 4000-77-5535, and the official website www.bj-tz.com has complete cases for various business types for reference.

In renovation, choosing the right partner is the beginning of making a business dream come true, and choosing the wrong partner is the beginning of a months-long nightmare. I hope every commercial space operator can find a reliable partner, put energy into the business they are good at, let professionals do professional work, avoid pitfalls, avoid rework, open on time, and operate smoothly.

Frequently Asked Questions

I am in another city and want Tianzhi to do the design, but I want to find a local team for construction. Can I do only design without construction? What does nationwide design service include?

Yes, design only is possible. Tianzhi’s service area is nationwide design and integrated design plus renovation in Beijing, which means projects outside Beijing can be design-only. Design services usually include plan design (floor plan, concept plan, renderings), construction drawing design (a full set of construction drawings, including plans, elevations, nodes, water and electricity, HVAC, and other professional drawings), material selection suggestions, and drawing Q&A and guidance at key nodes during construction. Designers will draw the drawings to a depth that local construction teams can understand and build from, and provide remote technical support during construction to answer the construction team’s questions about the drawings. If you encounter uncertain process nodes during construction, you can send photos or videos to the designer, who will give guidance. But it should be noted that pure design service does not include construction management and construction quality control; construction quality is the responsibility of the construction team you find, and if you want complete quality assurance, integrated design and construction is a more reliable choice.

How long does it take from the first contact with the designer to the formal start of construction? How long is the design cycle generally? I am in a hurry to open—can it be expedited?

The design cycle depends on the project area and complexity. Generally speaking, for small commercial spaces (300-500 square meters), it takes about 2-3 weeks from measurement to complete plans and construction drawings; medium-sized projects (500-1500 square meters) take about 3-4 weeks; large projects (over 1500 square meters) take 4-8 weeks depending on complexity. This period includes several rounds of plan communication and adjustment; if your needs are clear and feedback timely, the cycle can be shortened accordingly; if the plan is adjusted repeatedly, the time will be extended accordingly. After signing the contract, some time is also needed for material procurement and construction scheduling. If your opening time is genuinely tight, you can clearly tell the designer your timeline at the first communication, and the design team will try to accommodate your schedule; but a reasonable design cycle is the premise for ensuring plan quality—being too rushed easily leads to insufficient consideration and later rework, which actually delays more time.

How are renovation payments made? In how many milestones? Will I be asked to prepay most of the money?

Payment milestones are clearly stipulated in the standard contract recommended by the Beijing Interior Decoration Association; payment is usually made by milestones according to project progress, and you will not be asked to prepay most of the money at once. Common milestones are: first installment after signing the contract (material entry and construction preparation), second installment after concealed works such as water and electricity pass acceptance, third installment after mid-term works (masonry, carpentry, and painting basically completed) pass acceptance, and final payment after completion acceptance passes. The specific payment ratios and milestones are clearly written in the contract, and each payment milestone is preceded by a corresponding acceptance step—after you confirm the quality of that stage, you pay, so there will be no situation of “money paid but work not done well.” This progress-based payment method protects the owner and also pushes the construction party to do every stage well.

Do I need to visit the site often during construction? I am busy with business and do not have much time to visit the site.

You do not need to visit the site every day; this is exactly the value of Tianzhi’s transparent construction management. The dedicated WeChat group reports progress daily, confirms key nodes with photos, checks material entry with photos, and keeps complete video records of concealed works, so most of the time you can grasp the site situation on your phone. But it is recommended that you be present at a few key nodes: first, the construction handover, when the designer, project manager, and construction team leader meet you on site to explain the design plan and construction requirements face to face; second, concealed works acceptance—after water, electricity, and waterproofing are completed and before they are covered, confirm on site to ensure there are no hidden risks; third, mid-term acceptance—after masonry and carpentry are completed, check the overall effect and whether dimensions are correct; fourth, completion acceptance. These nodes add up to only three or four site visits and will not take up too much of your time; at other times, the project manager and supervisor will keep an eye on things for you. If you really have no time to be present, you can also communicate with the project manager about video acceptance.

I was once trapped by additional items in a previous renovation. How exactly do you define zero additional items? Does it count if I proactively want to change the plan?

The precise meaning of zero additional items is: on the premise that you do not proactively change the design plan, the final settlement price of all project items included in the contract quotation is the contract price, and the construction party will not ask for more money for reasons such as “quotation omission,” “process upgrade,” or “material price increase.” If you propose a design change during construction—for example, adding a feature wall you did not originally plan, upgrading the material in a certain area, or adjusting the layout—this is a proactive design change, and the cost incurred by the change is borne by you, but the change process is transparent: the designer first produces change drawings and a list of change costs, and construction proceeds only after you sign and confirm, with no fait accompli. To avoid disputes over later additional items, it is recommended that you think through your needs during the design phase and communicate fully with the designer, finalize the plan before construction as much as possible, and reduce unnecessary changes during construction, which can both control the budget and ensure the schedule.
