Prefabricated House Construction Case Sharing

Prefabricated house construction offers advantages such as fast construction speed, reliable quality, and controllable costs, with successful application cases both domestically and internationally.

I. Domestic Rural and Emergency Scenario Applications

1. Prefabricated Houses in Rural Henan: Utilizing a fully reinforced concrete structure with a 70-year warranty, these houses boast high durability. Construction efficiency is significantly improved, with the main structure of a 200㎡ house requiring only 4 hours for hoisting and a maximum of 2 hours for foundation installation. The comprehensive construction cost is approximately 300 yuan/㎡, with a total cost of around 70,000 to 80,000 yuan. This model is suitable for rural self-built housing scenarios, greatly shortening the construction period and reducing labor costs through standardized factory production and rapid on-site assembly.
2. Prefabricated Cement Houses in Qixian, Henan: Taking a three-story villa as an example, the factory completes steel bar binding, mold assembly, and concrete pouring through a mechanized process, with a single module production cycle of only 7 days and dimensional errors controlled within 2 millimeters. On-site, a 50-ton crane and intelligent positioning system are used, with the main structure of a 200㎡ villa requiring only 4 hours for installation and a 100㎡ house taking only 5 days from bare land to occupancy, achieving 'instant installation and occupancy'.
3. Shenzhen Anti-epidemic Prefabricated House Project: During the 2024 anti-epidemic efforts in Shenzhen, 300 isolation wards were constructed within 48 hours, reducing the traditional construction period by 90%. The project adopted a modular design, allowing for rapid assembly through standardized components to meet the urgent medical facility needs. It was praised by the WHO as a 'construction miracle', highlighting the efficiency of prefabricated houses in emergency scenarios.

II. International Export and Customized Applications
China's prefabricated houses have achieved large-scale exports. For example, 63 sets of elderly care apartment modules purchased by the UK were customized by the factory in terms of layout, style, and functionality according to overseas demands. After landing, all assembly was completed in just 14 days, improving efficiency by over 60% compared to the traditional six-month construction period. This case demonstrates that prefabricated houses can meet diverse needs through flexible production lines and break through geographical construction limitations through global logistics and rapid on-site assembly, providing efficient solutions for the international construction market.

III. Technological Advantages and Industry Trends
The core advantages of prefabricated houses lie in industrialized production and prefabricated construction: the main structure is manufactured in the factory, reducing on-site wet operations and improving quality stability; modular design supports flexible combinations to adapt to different scenario needs; intelligent hoisting and positioning technologies ensure construction accuracy. With the advancement of the 'dual carbon' goals, the energy-saving and emission-reducing characteristics of prefabricated houses (such as reducing construction waste and lowering energy consumption) will further promote their popularity, becoming an important direction for the future development of industrialized construction.
