On-site Prefabricated Housing

On-site prefabricated housing is a modern construction method where the main structure of the house is prefabricated in a factory and then transported to the site for assembly. It offers advantages such as fast construction, stable quality, environmental protection, and energy efficiency, making it suitable for rapid housing construction scenarios.

Definition and Characteristics

The core of on-site prefabricated housing lies in "factory prefabrication + on-site assembly." Its structural components, such as walls, roofs, and floors, are produced in a factory in a standardized manner, ensuring precise dimensions and stable quality through precision molds and automated equipment. Compared to traditional on-site pouring, the factory environment avoids weather interference, reduces material waste, and results in stronger and better-sealed components. After being transported to the site, a professional team quickly assembles them through bolt connections, welding, and other methods to form a complete building structure.

Process and Advantages

1. Custom Design: Users can choose the size, layout, and appearance of the house according to their needs, and even incorporate smart home systems. For example, prefabricated houses in the US market can be equipped with personalized designs such as panoramic floor-to-ceiling windows and solid wood decks.
2. Factory Prefabrication: Component production cycles are short, and quality is controllable. Taking the case of Tongzhou, Beijing, as an example, an 80-square-meter house built with traditional brick-and-mortar construction takes 8 months, while the prefabricated method takes only 45 days.
3. Transportation and Assembly: Professional logistics transport the components to the site, and the construction team completes the construction through modular assembly. Imported cases in the US show that the entire process from order placement to occupancy takes no more than 90 days, much faster than the 6-12 months required for local housing construction.
4. Core Advantages:
   • Short Construction Period: Factory and on-site operations are carried out in parallel, saving more than 50% of the time.
   • Stable Quality: The factory environment eliminates human errors, resulting in a higher pass rate for component strength.
   • Environmental Protection and Energy Efficiency: Reduces on-site wet operations, lowers dust and noise pollution, and increases material recycling rates by 30%.
   • Cost Control: Standardized production reduces labor costs, and the overall cost is 15%-20% lower than traditional methods.

Applicable Scenarios

1. Rural Self-built Houses: Meet the demand for rapid occupancy, such as the suburban self-occupied cottages in the Tongzhou, Beijing case.
2. Suburban Residential Housing in Cities: Suitable for homebuyers who are sensitive to construction timelines and pursue cost-effectiveness.
3. Temporary Buildings: Such as post-disaster reconstruction and construction site dormitories, which can be quickly deployed and easily dismantled.
4. Overseas Housing Market: Chinese prefabricated houses are exported to the US, seizing market share with their "move-in ready" advantage, especially popular among young people and investors.
