Construction of Prefabricated Modular Houses

Constructing prefabricated modular houses is a building method where the main structure, enclosure structure, etc., are prefabricated in a factory and then assembled on-site. It offers advantages such as high efficiency, low cost, flexibility, and environmental friendliness, but it has high requirements for the industrial base and has been widely applied in various scenarios.

Construction Method and Core Characteristics Prefabricated modular houses are produced through standardized factory production of the main building structure, enclosure structure, equipment pipelines, and interior decoration, forming prefabricated assembled space modules, which are then transported to the site for assembly and connection. Their core characteristics are standardized design, factory-based production, and on-site assembly construction. Through modular design, the universality and interchangeability of building components are achieved, ensuring efficient collaboration between production and construction.

Main Advantages

1. High Construction Efficiency: Factory prefabrication and on-site construction are carried out simultaneously, significantly shortening the construction period. For example, rural houses can be built within 14 days, and the overall construction cycle is reduced by about 50% compared to traditional methods. The construction period of a certain affordable housing project in Shanghai was compressed from 2.5 - 3 years to 1 year. The construction cycle of modular buildings is generally shortened by more than 60%.
2. Lower Cost: Standardized factory production reduces material waste by 30% and avoids the impact of weather on construction, resulting in a 20% reduction in overall costs.
3. Flexible Space Combination: Modules can be freely combined like "LEGO" blocks, supporting overall relocation and reuse to meet the needs of different scenarios.
4. Good Environmental Performance: Construction waste is reduced by 50% - 80%. Combined with energy-saving technologies such as photovoltaic curtain walls, it reduces noise, dust, and traffic congestion. For example, the Shenzhen affordable housing project significantly reduced on-site pollution through cast-in-place connection methods.

Industrial Base and Application Scenarios Prefabricated modular houses require the support of a technical system, production system, and industrial cluster, with high requirements for supply chain collaboration. Currently, this technology has been widely applied in fields such as residential housing, schools, and hospitals. Cities like Guangzhou and Shenzhen in China have introduced policies to promote its development. On May 8, 2026, the first concrete module hoisting was completed for the affordable rental housing project in the Dinghui Temple North Plot in Haidian District, Beijing, marking the implementation of Beijing's first concrete modular affordable housing project and providing a demonstration case for the industry.
