Prefabricated Integrated Concrete House

A prefabricated integrated concrete house is a prefabricated assembly-type building form that produces building components through industrialization and assembles them on-site, featuring high efficiency, cost-effectiveness, and environmental friendliness.

1. Technical Types and Core Components
This technology covers prefabricated concrete structures and steel structures, with main components including prefabricated products such as beams, slabs, walls, and columns. For example, a prefabricated cement integrated house uses wall panels and floor slabs made of reinforced concrete in advance at the factory, which are then directly hoisted at the construction site. Taking a 200-square-meter villa as an example, the main structure can be assembled within 4 hours, significantly improving the construction speed.

2. Construction Efficiency and Cost Advantages
The construction period is shortened by more than 60% compared to traditional buildings. For example, in a public housing project in Shenzhen, Guangdong, through the assembly of 6,028 concrete modules, the completion and delivery time was shortened from 2.5 - 3 years to 1 year, and the on-site labor force was reduced by about 50%. In terms of cost, the construction cost of the main structure of a 100-square-meter house is about 100,000 - 120,000 yuan, which is 30% cheaper than a brick-concrete structure, and the total package cost can be controlled within 150,000 yuan (it is necessary to choose a brand with a 70-year quality guarantee and a seismic report).

3. Quality and Environmental Performance
The structure adopts a C35 concrete and thickened steel bar framework, which has been tested to withstand magnitude-8 earthquakes and typhoons of force 12. Factory production reduces material waste, and construction waste is reduced by more than 70%. For example, the earthquake relief housing in Jishishan, Gansu, was built within 72 hours, with a simulated test displacement of only 3 centimeters and excellent winter insulation performance.

4. Application Scenarios and Market Potential
It is widely used in domestic fields such as residential housing, factory buildings, and public housing, such as the prefabricated shear wall residential structural system developed by Vanke Group. The overseas market demand is growing significantly. In the first four months of 2026, the export value of movable houses in the customs area under the Guangzhou Customs was 1.4 billion yuan, a year-on-year increase of 38.1%, indicating international market recognition of standardized and rapid construction technologies.

5. Design Limitations and Considerations
The standardized production of prefabricated components may limit design flexibility. For example, rounded balconies require an additional 20% customization fee. When selecting suppliers, it is necessary to focus on examining their qualifications to ensure that the products meet seismic standards and provide long-term quality guarantees, so as to balance personalized needs and cost control.
