Industrial Model Prefabricated Housing

Industrial model prefabricated housing is a form of architecture that involves the industrial production of building components and their on-site assembly. It is also known as prefabricated assembled buildings or modular buildings.

I. Core Characteristics
The core of prefabricated housing lies in breaking down the building into independent modules (such as beams, slabs, walls, columns, etc.), which are prefabricated in factories and then transported to the site for assembly, forming a construction mode similar to 'building blocks'. This approach enables standardized production and efficient assembly of building components, significantly enhancing construction efficiency. For example, the Nanjing Jindi Yufang project adopts a prestressed prefabricated concrete assembled integral frame structure system, while the Shenzhen affordable housing project is assembled from 6,028 concrete modules, both demonstrating the flexibility of modular design.

II. Technical Systems and Component Types
The technical systems cover two main directions: prefabricated concrete structures and steel structures. Concrete structures primarily consist of prefabricated wall panels, floor slabs, and other components, with structural safety enhanced through steel-concrete integral pouring techniques. Steel structures, characterized by lightweight and high strength, are suitable for ocean transportation needs. Component types include prefabricated wall panels, floor slabs, functional units (such as kitchen and bathroom modules), etc. Some projects also adopt wooden structures to meet specific scenario requirements. Chinese enterprises focus on steel and concrete technologies, catering to both domestic market demands and overseas export standards.

III. Application Scenarios and Market Advantages
The application scenarios of prefabricated housing have expanded from early factories and residential buildings to high-rise buildings, affordable housing, and overseas projects. Chinese-made prefabricated housing is popular overseas due to its cost-effectiveness and environmental friendliness. For example, in the first four months of 2026, the export value of movable houses from the Guangzhou Customs area reached 1.4 billion yuan, a year-on-year increase of 38.1%. Its advantages include:

1. High Construction Efficiency: Through parallel operations, automated production lines, and intelligent management, the construction period is shortened by more than 60% compared to traditional methods;
2. Significant Environmental Benefits: On-site labor is reduced by about 50%, while noise, dust, and construction waste are also minimized;
3. Enhanced Structural Safety: Modular buildings adopt steel-concrete integral pouring and other techniques, addressing issues such as weak earthquake resistance and limited lifespan of traditional prefabricated panel houses.

IV. Historical Development and Technological Iteration
China's prefabricated concrete technology originated in the 1950s, underwent the formation of a technical system in the 1970s, and experienced a stagnation in the mid-1980s before reviving in the 21st century due to environmental demands. Existing traditional prefabricated panel houses are gradually being replaced due to their performance limitations, while modular buildings have become the mainstream direction through technological innovations (such as high-strength connection nodes and intelligent monitoring systems), driving the architectural industrialization towards efficiency and sustainability.
