Prefabricated Houses and Modular Buildings

Prefabricated houses and modular buildings are construction models that break down buildings into independent modules, which are manufactured in factories and then transported to the site for assembly. This approach offers advantages such as short construction periods, controllable quality, energy conservation, and environmental protection, with wide application scenarios and promising development prospects.

Core Features and Construction Models
Modular buildings achieve efficient construction through standardized design, factory-based production, and assembly-based construction. The main building structure, enclosure, equipment pipelines, and interior decoration are all completed in the factory, forming standardized prefabricated modular spaces. This "building block" construction method transforms traditional on-site construction into a combination of factory prefabrication and on-site assembly, significantly improving construction efficiency and precision.

Significant Advantages

1. Substantially Shortened Construction Period: The construction period is reduced by more than 60% compared to traditional buildings, with the total period shortened by about 50%. For example, a public housing project in Shenzhen, Guangdong, was assembled using 6,028 concrete modules, reducing the construction period from 2.5-3 years to 1 year; rural housing projects can be completed in as fast as 14 days.
2. Strictly Controllable Quality: Each module is equipped with a detailed "ID card" recording project name, product model, and production date. Steel bar positioning accuracy is measured in millimeters, with error control far superior to on-site construction, ensuring building quality stability.
3. Outstanding Energy Conservation and Environmental Protection Benefits: Construction waste is reduced by about 80%, and sustainable materials and recycling technologies are used to minimize environmental impact, aligning with green building trends.
4. Superior Maintenance and Seismic Performance: Modular structures facilitate easy maintenance and replacement, and standardized design enhances overall seismic resistance, making them suitable for earthquake-prone areas.
5. Significant Cost-Effectiveness: For overseas projects, factory-based production reduces on-site labor requirements, resulting in shorter cost recovery periods and higher certainty, especially suitable for regions with high labor costs.

Application Scenarios and Development Status
Modular buildings have been widely applied in emergency scenarios such as medical relief, military barracks, and post-disaster resettlement, as well as in civil areas such as housing, schools, hospitals, and hotels. For example, foldable houses are used for temporary post-disaster resettlement, dual-wing expandable houses serve both residential and office needs, and 20-foot luxury apartments are suitable for outdoor adventures and scenic area homestays. At the policy level, cities like Guangzhou and Shenzhen have introduced support measures, with the Dinghui Temple North Plot public housing project in Haidian District, Beijing, becoming the city's first concrete modular public housing benchmark. In the international market, China's modular building exports nearly tripled from 2015 to 2025, with a 45% growth rate in the first quarter of 2026, indicating持续提升 overseas recognition.
