Beijing Prefabricated Component Housing

Beijing prefabricated component housing is a building form that adopts a modular construction model, featuring advantages such as short construction periods and controllable quality. These advantages are reflected in policy regulations and the richness of market products, and there are already successful application cases.

Construction Model and Definition

Beijing prefabricated component housing falls within the scope of modular buildings (prefabricated houses). Its core involves dividing the entire building into independent modules, completing structural manufacturing, interior decoration, and equipment installation in a factory, and then transporting them to the construction site for assembly. This construction model breaks through the spatial and temporal limitations of traditional on-site construction, achieving standardized and large-scale manufacturing through industrial production.

Core Advantages

Compared with traditional construction techniques, prefabricated component housing offers significant advantages:
Significantly shortened construction periods: Taking the affordable housing project in Shenzhen, Guangdong, as an example, five nearly 100-meter residential buildings were assembled using 6,028 concrete modules, reducing the completion and delivery time from 2.5-3 years to 1 year; the renovation project of Building 28 in Sanlihe Area 1, Xicheng District, Beijing, was completed with roof sealing in just 46 days.
Controllable quality and environmental protection: Factory-based production allows for strict control over material quality and construction precision, reducing human errors; at the same time, on-site work volume is reduced by about 50%, significantly lowering environmental impacts such as noise, dust, construction waste, and traffic congestion.
Efficient resource utilization: Modular design supports repeated disassembly, assembly, and relocation, extending the building's lifecycle and aligning with the trend of green building development.

Policy and Market Support

Beijing promotes the development of prefabricated component housing through policy guidance and market regulation:
Policy level: The Beijing Municipal Commission of Housing and Urban-Rural Development and the Beijing Municipal Administration for Market Regulation jointly formulated the 'Demonstration Text of the Purchase Contract for Prefabricated Concrete Components for Assembled Buildings in Beijing (Draft for Solicitation of Comments)', which was open for public comment in April 2024. The aim is to regulate the procurement behavior of prefabricated components and protect the rights and interests of upstream and downstream entities in the industrial chain.
Market level: The product range is diverse, covering box-type light steel houses, modern box-type houses, prefabricated color steel houses, etc., with brands including Wanjinlong and Zhuode Building Materials. Prices vary significantly depending on specifications; for example, the unit price of box-type light steel houses is not less than 7,500 yuan each, modern box-type houses cost not less than 12,000 yuan per set, and prefabricated mobile houses are priced by area (not less than 225 yuan per square meter for areas ≥100 square meters).

Typical Application Scenarios

Prefabricated component housing has been implemented in areas such as old building renovation and affordable housing construction in Beijing:

• Old building renovation: The Building 28 project in Sanlihe Area 1 quickly completed the main structure construction using modular technology, shortening the relocation period for residents.
• Affordable housing construction: The Shenzhen project verified the feasibility of modular construction for high-rise residential buildings, providing technical references for similar projects in Beijing.
