Prefabricated Assembled Housing

Prefabricated assembled housing is a building form that involves the industrial production of building components and their on-site assembly. It offers advantages such as short construction periods and environmental friendliness, with major types including panel-assembled, box-assembled, and frame-assembled housing, widely used both domestically and internationally.

Core Definition and Characteristics

Prefabricated assembled housing, also known as prefabricated buildings or assembled housing, centers on the industrial production of building components (such as beams, slabs, walls, and columns) and their on-site assembly. This building form primarily uses recyclable materials and features characteristics such as short construction periods, light weight, and low transportation energy consumption. The components can be widely applied to different building parts. For example, Ningbo once assembled a fully prefabricated rural house in seven days, and rural areas in South Korea also completed the main structure construction in 14 days, fully demonstrating its efficiency.

Main Types and Technologies

1. Panel-assembled: Using prefabricated wall panels and floor slabs as core components, it can expand the usable area but has limited design flexibility.
2. Box-assembled: By combining prefabricated functional units (such as kitchens and bathrooms), construction speed increases by 50%-70%, but it has higher requirements for transportation and lifting equipment.
3. Frame-assembled: Supported by steel or concrete frames, it is suitable for high-rise buildings and offers strong structural stability.
   Technologically, it covers prefabricated concrete structures and steel structures, with a high degree of standardization in component production and controllable quality.

Advantages and Applications

• Shortened construction period: Industrial production and on-site assembly occur simultaneously, reducing on-site wet work and shortening the construction period by 30%-50% compared to traditional buildings.
• Environmental friendliness: It reduces construction waste (e.g., the industrial base in Fujian Province achieves a waste reduction of over 70%) and lowers pollution, aligning with sustainable development concepts.
• Cost control: Domestic pilot projects (such as assembled rural houses in Fangshan District, Beijing) cost about 1,800 yuan per square meter, lower than traditional self-built houses, and policy support (such as earthquake resistance and energy-saving incentives) further reduces costs.
• International application: Australia has prefabricated housing supermarkets, and Chinese-made prefabricated houses are popular overseas, with Guangzhou Customs' export volume increasing by 38.1% year-on-year in the first four months of 2026.

Typical Cases

• Domestic: Beijing piloted assembled rural houses in 2010, promoting their popularity with financial incentives; Fujian Province established an industrial base with policy support to achieve efficient and green construction.
• Foreign: Australian prefabricated housing supermarkets offer one-stop shopping services to meet consumer personalized needs.
