Prefabricated House Combination

Prefabricated house combinations mainly include two forms: modular construction and prefabricated assembled construction.

Modular Construction

Modular construction breaks down a building into independent modules, which are manufactured in a factory and then transported to the construction site for assembly. Its core advantages are significant:

• Short Construction Period: Compared to traditional construction, the construction cycle can be shortened by more than 60%. For example, in a public housing project in Shenzhen, Guangdong, assembled from 6,028 concrete modules, the completion and delivery time was reduced from 2.5 to 3 years to just 1 year.
• Controllable Quality: The position of each steel bar is precisely located, with errors and precision controlled in millimeters. Each 'building block' has a detailed 'ID card' containing information such as the project name, product model, and production date.
• Energy Efficiency and Environmental Protection: Most construction processes are completed in the factory, with on-site cast-in-place connections, significantly reducing noise, dust, construction waste, and traffic congestion at the construction site.
• Easy Maintenance: Flexible maintenance and continuously expanding application scenarios. Market research institutions predict that the global modular construction market size will exceed $142.8 billion by 2030.

Prefabricated Assembled Construction

Prefabricated assembled construction involves the industrial production of building components and their assembly on-site, with main types including panel-assembled, box-assembled, and frame-assembled construction.

• Technology and Components: The technology covers prefabricated concrete structures and steel structures, with components including prefabricated products such as beams, slabs, walls, and columns.
• Advantages: It has advantages such as shortened construction periods and reduced pollution.
• Characteristics of Specific Types: Panel-assembled buildings use prefabricated wall panels and floor slabs as core components, which can expand the usable area but are limited by design flexibility. Box-assembled construction combines prefabricated functional units, increasing construction speed by 50%-70%, but has higher requirements for transportation and lifting equipment.

Application Cases

• Domestic: Companies such as Vanke Group have developed prefabricated shear wall residential structural systems and applied prefabricated frame technology in projects. For example, the Nanjing Jindi Yufang project adopted a prestressed prefabricated concrete assembled integral frame structural system.
• Overseas: Chinese-made prefabricated houses are selling well overseas. According to customs data, in the first four months of 2026, the Guangzhou Customs District exported RMB 1.4 billion worth of mobile homes, a year-on-year increase of 38.1%. Products such as the globally sold F-01 88m² fully furnished modular apartments adopt a new modular construction structure, are produced with high quality in factories, and have features such as 8-degree earthquake resistance, thermal insulation, energy efficiency, environmental protection, mobility, and relocatability, with a wide range of applications.
