From a 102㎡ Jianxinyuan Project to 15 Registered Cases: The Project File of Beijing Chaofan Decoration

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.
