Prefabricated Modular Housing

Prefabricated modular housing is a form of construction that involves the industrial production of building components and their on-site assembly. Modular construction, as a highly integrated branch of prefabricated housing, is characterized by its efficiency, environmental friendliness, and wide range of applications, with Chinese products demonstrating significant competitiveness in the international market.

Types and Technical Systems

The core of prefabricated modular housing lies in "industrial prefabrication + on-site assembly," primarily divided into three categories:

1. Panel-based Assembly: This type focuses on prefabricated wall panels, floor slabs, and other components, which are assembled into an integral structure using connectors. It is suitable for multi-story residential or public buildings.
2. Box-based Assembly: Complete rooms (such as bathrooms and bedrooms) are prefabricated as independent modules and stacked directly on-site. This approach is commonly used in standardized settings like hotels and dormitories.
3. Frame-based Assembly: A frame structure is formed using prefabricated beams and columns, with non-load-bearing components like wall panels added later. This method offers high flexibility and is suitable for complex buildings such as office towers and hospitals.
   Technically, it encompasses prefabricated concrete structures (e.g., prefabricated shear walls and composite slabs) and steel structures (e.g., light steel frame modules), with component production precision reaching the millimeter level to ensure controllable on-site assembly errors.

Core Advantages of Modular Construction

As an upgraded model of prefabricated construction, modular construction achieves breakthroughs through "full factory manufacturing + on-site assembly":

• Enhanced Construction Efficiency: Construction periods are reduced by over 60% compared to traditional methods. For example, a social housing project in Shenzhen utilized 6,028 concrete modules, shortening the completion time from 2.5-3 years to just 1 year.
• Consistent Quality Control: Each module is equipped with a unique "ID card" recording production information, with errors controlled to the millimeter level to avoid human deviations during on-site construction.
• Significant Environmental Benefits: Over 70% reduction in construction waste, along with decreased noise and dust pollution, alleviates traffic pressure. Regions like Fujian have established industrial bases through policy guidance to promote green construction.
• Diverse Application Scenarios: From residential (apartments, dormitories) to commercial (office buildings, hotels), and even extending to special-purpose buildings like data centers, it covers the entire lifecycle of construction needs.

International Competitiveness of China's Prefabricated Construction

China's exports of prefabricated modular housing have surged: export value nearly tripled from 2015 to 2025, with a 45% growth rate in the first quarter of 2026. Guangzhou Customs data shows a 38.1% year-on-year increase in export value of movable houses in the first four months of 2026. Its advantages in going global include:

• Cost Efficiency: Large-scale production reduces unit prices, combined with savings in on-site labor costs, resulting in outstanding overall cost-effectiveness.
• Controllable Construction Period: Modular design significantly shortens on-site construction cycles. For instance, a senior living apartment project in the UK completed the hoisting of 63 modules in just two weeks.
• Policy Support: The construction of domestic industrial bases aligned with overseas standards promotes technology exports and enhances brand recognition.

Currently, prefabricated modular housing has become the core carrier of the global trend toward industrialized construction. Leveraging its complete industrial chain and technological innovation, China is advancing from "product exports" to "standard exports."
