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.
