Domestic Prefabricated Modular Housing

Domestic prefabricated modular housing adopts a new building model characterized by standardized design, factory-based production, and on-site assembly. It involves breaking down buildings into independent unit modules, which are prefabricated in factories and then assembled on-site.

I. Core Features The core of prefabricated modular housing lies in “modularity”. Through standardized design, buildings are divided into independent units (such as concrete modules and steel structure modules). Each module undergoes prefabricated production in factories, including structural, piping, and decoration processes, and is then transported to the site for rapid assembly. This model achieves the industrial transformation of building production and breaks away from the reliance on on-site construction in traditional buildings.

II. 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, assembled 6,028 concrete modules, compressing the completion and delivery time from 2.5 - 3 years to 1 year. The Dinghui Temple North Plot project in Haidian District, Beijing, as the first concrete modular public housing project in Beijing, marked the start of efficient construction with the hoisting of the first module.
2. Precise and Controllable Quality: Each module is equipped with an “ID card” that records information such as the project name, product model, and production date. The precision of steel bar positioning is measured in millimeters, and the error control is far superior to that of on-site construction.
3. Outstanding Environmental Benefits: It can reduce construction waste by about 80%, significantly lowering on-site noise, dust, and traffic congestion, aligning with the trend of green building development.
4. Convenient and Flexible Maintenance: The modular structure facilitates later maintenance or renovation. For example, replacing a single module can complete a local upgrade.

III. Policy and Industrial Support At the policy level, cities such as Guangzhou and Shenzhen have introduced special policies to promote the application of modular buildings. The project in Haidian District, Beijing, marks the implementation of policies in the field of affordable housing. At the industrial level, this model places extremely high demands on the technical system, production system, and industrial clusters, requiring enterprises to possess full-chain capabilities. For example, China State Construction HaiLong Technology delivers 20,000 - 30,000 modules annually. The steel structure integrated module system developed by Guangdong CIMC Construction covers fields such as high-end offices, hotels, and data centers and has been exported to more than 20 countries, including the United Kingdom and Australia.

IV. Expansion of Application Scenarios Prefabricated modular housing has extended from early temporary buildings to permanent buildings, covering diverse scenarios such as public housing, schools, hospitals, and data centers. Its combination of standardization and flexibility makes it an important solution for addressing rapid urban construction, emergency needs, and sustainable development.
