Prefabricated Integrated Housing

Prefabricated integrated housing is a form of architecture that involves the industrial production of building components and their on-site assembly. It falls under the category of prefabricated architecture and is characterized by efficiency, environmental friendliness, and flexibility.

Technical Types and Components

Prefabricated integrated housing encompasses various technical types, including prefabricated concrete structures, steel structures, and modern timber structures. Its core components are prefabricated beams, slabs, walls, and columns, which are produced through standardized designs to achieve modular production. More highly integrated modular buildings break down the structure into independent functional units (such as ceilings, floors, and plumbing and electrical systems), which are manufactured in factories and then transported to the site for assembly into a complete building. For example, American mobile homes adopt trailer-style designs with complete living facilities inside, allowing for quick connection to waterways and power sources.

Production and Construction Process

This architectural form adopts a model of standardized design, factory-based production, and modular construction. Factories utilize automated production lines operating in parallel to significantly enhance production efficiency. For instance, the CSCEC Hailong Intelligent Construction Industrial Park in Shenzhen, Guangdong, can deliver 20,000 to 30,000 modules annually, reducing construction periods by over 60% compared to traditional buildings. During on-site construction, prefabricated components are installed using tower cranes, with each component labeled with project name, model, and production date to ensure precise and controllable construction. A real estate development site in Shanghai achieved efficient assembly through this method, significantly reducing on-site work time.

Advantages and Application Scenarios

1. Construction Period and Environmental Protection: Modular buildings can shorten construction periods by 50%-70% and reduce on-site noise, dust, and construction waste. A public housing project in Shenzhen, Guangdong, used 6,028 concrete modules to compress the completion and delivery time from 2.5-3 years to just 1 year.
2. Quality and Flexibility: Factory-based production controls component errors to the millimeter, ensuring architectural precision. While panel-based prefabricated buildings may have limited design flexibility, they can expand usable area; box-based prefabrication enhances construction speed through the combination of prefabricated functional units.
3. Policy and Market: Multiple regions in China have introduced policies to promote the development of prefabricated buildings. For example, starting from 2026, all residential land parcels auctioned in Guangzhou will implement prefabricated construction. In the first four months of 2026, the export value of mobile homes from the Guangzhou Customs District reached 1.4 billion yuan, a year-on-year increase of 38.1%, indicating significant market potential.

Typical Cases

Vanke Group has developed a prefabricated shear wall residential structural system and applied a prestressed prefabricated concrete integrated frame structural system in the Nanjing Jindi Yufang project. Additionally, the trailer-style design and integrated internal facilities of American mobile homes provide innovative solutions for temporary housing and mobile living.
