Changsha Prefabricated Assembled Housing

Changsha has formed a complete industrial chain and technological system in the field of prefabricated assembled housing, becoming a national benchmark city. Its development achievements are reflected in the following aspects:

I. Strong Industrial Foundation and Significant Demonstration Effect
Since being named a national demonstration city for prefabricated buildings in 2017, Changsha has cultivated 7 national-level and 11 provincial-level prefabricated building bases, as well as nearly 20 key production enterprises, covering the entire chain of R&D, production, design, and construction. For example, Broad Homes possesses world-class R&D capabilities for PC prefabricated concrete complete equipment, while Sany Group and Zhongmin Zhuyou have established modern service platforms, creating a clustered industrial effect.

II. Diverse Technological Systems and Wide Application Scenarios
The technological types cover panel, box, and frame prefabrication, primarily focusing on prefabricated concrete structures and steel structures. Prefabricated components include standardized products such as beams, slabs, walls, and columns. Typical cases include:

• Zhongmin Zhuyou Exhibition Hall: Workers completed villa construction within one day using prefabricated components, demonstrating efficient construction advantages;
• Broad Homes Automated Production Line: Components are identified with chips or QR codes, enabling precise hoisting and assembly with millimeter-level error control;
• Rural Housing Pilot Program: Launched in 2024, this initiative requires the main structures of rural houses to adopt concrete, steel, or timber structures, with all components factory-produced. Eligible projects can apply for subsidies of up to 50,000 yuan.

III. Clear Policy Drivers and Accelerated Market Promotion
According to the Hunan Province Action Plan for Improving Housing Quality, by 2026, the proportion of newly started prefabricated building area in Changsha's urban areas must reach 65%, promoting the increased use of green building materials in commercial housing projects and implementing "one material, one code" traceability management. Additionally, companies like Broad Homes have established or are constructing 80 prefabricated building factories globally, exporting products to countries such as Russia and Poland, expanding overseas markets.

IV. Enterprise Innovation Leading and Continuous Technological Iteration
After 21 years of development, Broad Homes has formed six generations of product technology systems, transitioning from single-component production to a multifunctional service platform. Companies like Sany Group and Zhongmin Zhuyou have integrated the industrial chain through digital technologies, enhancing production efficiency and quality stability. Through policy guidance, technological innovation, and industrial chain integration, Changsha has provided a replicable promotion model for the industry.
