Integral Prefabricated Concrete House

Integral prefabricated concrete houses are a type of pre-cast housing (prefabricated modular construction) that are manufactured industrially and assembled on-site. They offer advantages such as short construction periods, low costs, environmental friendliness, and earthquake and wind resistance. However, they have design limitations and are suitable for specific short-term or long-term scenarios, with a rapidly growing market.

Technical System and Component Types
Integral prefabricated concrete houses adopt a prefabricated concrete structure, with main components including prefabricated wall panels, floor slabs, beams, and columns. Some projects utilize a prestressed prefabricated concrete assembled integral frame structural system, such as the Nanjing Jindi Yufang project, which achieves overall stability of components through high-strength connection technology.

Construction Advantages

1. Shortened Construction Period: The combination of industrial production and on-site assembly significantly improves efficiency. For example, the main structure of a 200-square-meter villa can be assembled in as little as 4 hours, saving approximately 90% of the time compared to traditional construction methods.
2. Cost Reduction: Optimization of materials and construction processes reduces costs. The main structure of a 100-square-meter house costs approximately 100,000 to 120,000 yuan, which is 30% cheaper than a brick-and-mortar structure.
3. Environmental Performance: Industrial production reduces on-site wet operations, resulting in a reduction of construction waste by more than 70% (as demonstrated in application cases in Fujian Province's industrial base).
4. Earthquake and Wind Resistance: Utilizing C35 concrete and reinforced steel frames, these houses can withstand earthquakes of magnitude 8 and typhoons of category 12. During the Gansu Jishishan earthquake, 2,000 relief houses were built and put into use within 72 hours, demonstrating their emergency response capabilities.

Application Scenarios and Limitations

1. Suitable Scenarios: For short-term use, they can be rented on a monthly basis (e.g., homestays can triple their annual income). For long-term use, it is advisable to choose brands with a 70-year warranty (such as Broad Homes).
2. Design Limitations: Standardized components limit design flexibility, and modifications require an additional 20% customization fee (e.g., rounded balconies).

Market Development
China's prefabricated housing technology is mature and in high demand overseas. In the first four months of 2026, the Guangzhou Customs District exported 1.4 billion yuan worth of mobile houses, a year-on-year increase of 38.1%, indicating strong international market demand.

Integral prefabricated concrete houses balance efficiency, cost, and performance through modular design, industrial production, and efficient assembly. However, it is necessary to weigh the trade-offs between standardization and customization based on demand. They hold great potential in the fields of green building and emergency response in the future.
