Requirements for Prefabricated Houses

The requirements for prefabricated houses vary depending on their type and application scenario, as detailed below:

Requirements for Prefabricated Rural Houses

• Construction Principles: Adhere to principles of modern functionality, structural safety, cost-effectiveness, environmental friendliness, and harmonious aesthetics, integrating local climate, topography, traditional customs, and architectural characteristics to meet the functional needs of modern rural residents.
• Structural Systems: Clearly define structural systems such as prefabricated concrete shear wall systems, EPS module cast-in-place concrete systems, and light steel frame systems, providing detailed design and construction specifications.
• Material Requirements: Utilize local materials and green, economical, or recyclable building materials whenever possible, prioritizing local resources and prohibiting the use of high-energy-consuming and excessively polluting materials.
• Design Requirements: Respect farmers' housing needs, reflect regional characteristics, consider age-friendly design, and ensure that floor plans and facades facilitate winter sunlight and summer ventilation. Houses should be oriented north-south, with simple and regular shapes, and functional spaces including bedrooms, dining areas, storage, and courtyards. Residential spaces should be divided to separate active and quiet areas.
• Construction Requirements: Construction should be carried out by professional teams or trained rural individual builders. A construction organization plan and construction scheme should be developed, covering component installation, joint construction plans, quality management, and safety measures.

Requirements for "Three-Panel" Application Projects

• Scope of Application: Includes newly built hospitals, hotels, and office buildings with a single building area of over 20,000 square meters, newly built school buildings over 5,000 square meters, newly built commercial residential buildings, apartments, affordable housing, and standard factory buildings with a single building area of over 10,000 square meters.
• Engineering Requirements: Concrete structure buildings should use interior partition panels, prefabricated stair panels, and prefabricated composite floor panels, with encouragement to use prefabricated exterior wall panels. Steel structure buildings should use interior partition panels and prefabricated exterior wall panels. Exterior walls should preferably use self-insulating panels such as prefabricated sandwich insulation wall panels. The total proportion of mandatory "three-panel" applications in a single building must not be less than 60%. Residential projects are encouraged to actively use prefabricated balconies, sunshades, air conditioning panels, and other prefabricated components to increase the prefabrication rate.

Conditions for Building Prefabricated Houses in Rural Areas

• Compliance with Village Planning: The construction site must comply with the approved village plan, and construction must not occur arbitrarily outside the planned area.
• Obtaining Relevant Approvals: Approvals including land use, planning permits, and construction permits (required when project investment exceeds 300,000 yuan or building area exceeds 300 square meters) must be obtained.
• Construction Enterprise Qualifications: Units undertaking construction tasks within village planning areas must possess corresponding construction qualification certificates or qualification review certificates. Individual craftsmen must also obtain construction qualification approvals, except for house repairs.
• One Household, One Residential Land Principle: Rural households are limited to one residential land plot, with the area not exceeding the standards set by provinces, autonomous regions, or municipalities directly under the central government.
