Suning Rural Prefabricated House Renovation

The renovation of prefabricated houses in rural areas of Suning should refer to modular construction scenarios, focusing on thermal insulation, moisture resistance, and localized needs, while strictly controlling construction qualifications.

1. Verify Enterprise Construction Qualifications

Modular construction falls within the scope of building construction, so it is essential to ensure that the partner enterprise has legal qualifications. For the renovation of prefabricated houses in rural areas of Suning, priority should be given to selecting enterprises holding a Building Construction Permit and Special Qualifications for Modular Construction, avoiding unqualified scattered construction teams. Qualification verification can be conducted by querying enterprise registration information on the official website of the local housing and construction department or requesting the enterprise to provide original qualification certificates for verification. Unqualified construction may lead to structural safety hazards and post-renovation maintenance disputes, which should be strictly avoided.

2. Strengthen Thermal Insulation and Moisture Resistance

Given the cold winters and heavy ground moisture in northern regions, the renovation of prefabricated houses should focus on enhancing thermal insulation and moisture resistance designs:

• Wall Insulation: Fill wall cavities with insulation materials such as polystyrene boards or rock wool boards, or install insulation and decoration integrated panels on exterior walls to reduce heat loss.
• Ground Moisture Resistance: Lay a moisture-proof membrane on the foundation, use anti-slip floor tiles or cement hardening for the ground, and reserve green belts or permeable bricks in corner areas to prevent moisture accumulation.
• Roof Insulation: Install XPS extruded polystyrene boards or foam glass boards on the roof, or design a double-layer roof structure to form an air insulation layer, improving summer insulation effects.

3. Plan Spaces Based on Local Living Habits

The renovation of prefabricated houses in rural areas of Suning should balance practicality and aesthetics, with reasonable planning based on local climate and living needs:

• Courtyard Functional Zoning: Harden the ground for drying grains and bedding, using anti-slip floor tiles; plant locally easy-to-grow flowers and vegetables in corner areas to form small vegetable gardens; reserve parking spaces for electric vehicles and storage areas for agricultural tools and miscellaneous items to avoid clutter.
• Drainage System Design: Reserve a 1%-2% slope on the courtyard ground, paired with simple drainage ditches, to ensure rapid drainage of rainwater and prevent foundation subsidence caused by water accumulation.
• Indoor Layout Optimization: Arrange main activity areas such as living rooms and bedrooms facing south to make full use of natural lighting; strengthen ventilation designs in damp areas such as kitchens and bathrooms, installing exhaust fans or fresh air systems.

4. Focus on Earthquake Resistance and Structural Safety

Although modular houses are prefabricated in factories, on-site assembly must strictly follow regulations. Avoid arbitrarily modifying load-bearing structures during renovation; if modifications are necessary, contact the original design unit to issue a reinforcement plan. Connections between walls and floor slabs, as well as around door and window openings, should be carefully inspected to ensure no cracks or looseness, with reinforcement if necessary.
