Rural Homestead Prefabricated Houses
Rural homestead prefabricated houses are rural residential houses assembled on construction sites from components prefabricated or partially prefabricated in factories, featuring characteristics such as rapid construction, adherence to specific principles, and diverse structural systems.
Definition and Characteristics: Prefabricated rural houses (prefab houses) are assembled from prefabricated components. For example, the main structure can be erected in just 14 days, with 5-ton foundation piles secured by base plates, beams connected using mortise-and-tenon joints, stairs installed like building blocks, followed by floor slab installation and grouting of component gaps.
Construction Principles: Adhere to principles of modern functionality, structural safety, cost-effectiveness, environmental friendliness, and aesthetic harmony, integrating local climate, topography, traditional customs, and architectural characteristics to meet the functional requirements of modern rural residents.
Structural Systems: Clearly define systems such as prefabricated concrete shear wall structures, EPS module cast-in-place concrete structures, and lightweight steel frame structures, providing detailed design and construction specifications.
Material Requirements: Utilize locally available and green materials, prioritizing recyclable or economically viable options while ensuring quality. Local materials should be preferred, and high-energy-consuming or excessively polluting materials are prohibited.
Design Requirements: Respect farmers' housing needs, reflect regional characteristics, incorporate age-friendly design, ensure favorable sunlight and ventilation through floor plan and facade design, maintain simple and regular shapes, include functional spaces such as bedrooms and dining areas, and separate living spaces by activity level.
Construction Requirements: Should be carried out by professional teams or trained rural individual builders. Develop construction organization plans and schemes that integrate design, production, and assembly principles, covering component installation, joint construction, quality management, and safety measures.
Comparison with Traditional Self-Built Houses: Advantages include standardized factory production, shortened construction periods through assembly, and immunity to adverse weather conditions. Disadvantages include relatively inferior quality, less stable structures, susceptibility to cracking and water leakage at module connections, and lower durability compared to traditional self-built houses, often used as temporary or construction site housing.
Market Situation: Not widely popular in rural China, with low acceptance among rural residents, but favored in European and American countries. China's prefabricated building exports grew by 45% in the first quarter of this year.
