Prefabricated Housing Model

The prefabricated housing model is a construction approach that utilizes factory-prefabricated components assembled on-site, offering advantages such as shorter construction periods, controllable quality, and energy efficiency and environmental protection. It has formed a complete industrial chain and achieved international development.

Also known as prefabricated modular construction or modular architecture, the core of the prefabricated housing model lies in breaking down buildings into independent modules or components (such as beams, slabs, walls, columns, etc.), which are prefabricated in factories and then transported to construction sites for assembly. The technical system encompasses prefabricated concrete structures and steel structures, with main types including:

1. Panel-based prefabricated buildings: These use prefabricated wall panels and floor slabs as core components, allowing for expanded usable area but with limited design flexibility.
2. Box-type prefabricated buildings: These are assembled from prefabricated functional units (such as bathrooms and kitchens), improving construction speed by 50%-70% but requiring higher transportation and lifting equipment.
3. Frame-based prefabricated buildings: These adopt a prestressed prefabricated concrete integrated frame structure system, exemplified by the Nanjing Jindi Yufang project.

Compared to traditional construction methods, the prefabricated housing model offers significant advantages:

• Shorter construction periods: Parallel operations in factories and automated production lines reduce construction cycles by over 60%. For example, a social housing project in Shenzhen, Guangdong, assembled from 6,028 concrete modules, saw its completion and delivery time reduced from 2.5-3 years to just 1 year.
• Controllable quality: Each component is equipped with an 'ID card' containing project name, product model, and production date, with design tolerances controlled in millimeters to ensure quality stability.
• Energy efficiency and environmental protection: Factory prefabrication reduces on-site noise, dust, and construction waste. Fujian Province has achieved over 70% reduction in construction waste through policy support, aligning with green building trends.
• Ease of maintenance: Modular design facilitates later repairs and replacements, extending the building's service life.

This model requires a strong industrial foundation, supported by technical systems, production systems, and industrial clusters. Currently, China's prefabricated housing industry has formed a complete industrial chain, with products covering high-end office buildings, hotels, schools, data centers, and other diverse categories. Its market extends to over 20 countries and regions, including the UK and Australia. According to customs data, in the first four months of 2026, the Guangzhou Customs District exported movable houses worth 1.4 billion yuan, a year-on-year increase of 38.1%, demonstrating its international competitiveness.
