Integrated Prefabricated Housing

Integrated prefabricated housing refers to houses where building modules are manufactured in factories and then transported to the site for assembly. It features short construction periods, controllable quality, energy conservation, and environmental protection, with the technology entering a stage of large-scale promotion and high-quality transformation.

I. Technical Principles and Advantages
Integrated prefabricated housing centers around modular construction, dividing buildings into independent modules. All processes, including ceiling, wall, and water and electricity pipeline prefabrication, are completed in factories. For example, a public housing project in Shenzhen, Guangdong, assembled 6,028 concrete modules, reducing the construction period from the traditional 2.5-3 years to 1 year, cutting on-site labor by about 50%, and significantly reducing noise and dust pollution. Its technical advantages are reflected in:

1. Parallel Operation Mode: Combining automated vertical warehouses and intelligent production lines, construction periods can be shortened by over 60%. For instance, the concrete module production line at the China Construction HaiLong Intelligent Construction Industrial Park has an annual delivery capacity of 20,000-30,000 modules. Millimeter-level precision control enhances the building's waterproofing, sound insulation, and earthquake resistance, with module reuse rates exceeding 90%.
2. Environmental Protection and Efficiency: Factory-based production reduces on-site wet operations, minimizing material waste and carbon emissions, aligning with green building trends.

II. Market Types and Application Scenarios
Integrated prefabricated housing mainly includes three types: steel, concrete, and wooden structures:

1. Steel Structure: Lightweight and suitable for ocean transport, commonly used in high-rise buildings and temporary facilities.
2. Concrete Structure: More akin to traditional living experiences, with high acceptance in the domestic market. For example, cement prefabricated integrated houses in Shandong use reinforced concrete integrated pouring processes, featuring corrosion resistance and mobility, with prices ranging from 7,500 yuan per set to 385 yuan per square meter depending on specifications.
3. Wooden Structure: Mostly used in low-rise residences or vacation villas, but with a small market share in China.

Application scenarios cover public housing, campuses, hospitals, and other livelihood sectors. As of June 2026, China Construction HaiLong's MiC technology has been implemented in 137 projects across 15 provinces and 24 cities nationwide, with a total construction area of 6.12 million square meters, demonstrating the potential for large-scale promotion.

III. Development Status and Trends
China's integrated prefabricated housing technology has entered a high-quality transformation stage, with corporate strengths concentrated in steel and concrete sectors. With policy support and growing market demand, the future will see development towards intelligence, standardization, and sustainability, further promoting the industrialization of the construction industry.
