Prefabricated Houses in Nanchong, Sichuan

The prefabricated houses in Nanchong, Sichuan, mainly include two forms: the renovation of prefabricated panel houses in old residential areas and packing-box units.

Renovation of Prefabricated Panel Houses in Old Residential Areas

In the courtyard at No. 28 Xiaokang Lane, Guoshan Street Community, Xicheng Subdistrict, Shunqing District, Nanchong, there are prefabricated panel houses built in 1989. Before renovation, these houses had numerous issues. The roofs were low and lacked protective measures, and the prefabricated panels had cracks running in all directions. Whenever it rained, water would drip through the cracks, seriously affecting the normal lives of the residents. In 2024, this courtyard was included in the old residential area renovation plan. After renovation, the roofs of the houses were comprehensively upgraded, adopting a multi-layer structure with upper-layer waterproofing, middle-layer insulation, and surface-layer protection. This design effectively solved the problem of water leakage, improved the living comfort and safety of the houses, and enhanced the living environment of the residents.

Packing-Box Units

Packing-box units are a convenient and efficient new type of temporary living solution in Nanchong. Compared with traditional temporary buildings such as movable panel houses and tents, they have significant advantages.

• Short Construction Period: Packing-box units adopt a modular design. Most of the work for each box is completed in the factory. After being transported to the site, they can be put into use with simple lifting, assembly, and pipeline connections, greatly shortening the construction time.
• Superior Performance: In terms of materials, they mostly use sturdy steel structural frames and high-performance composite wall materials, making them superior to traditional movable panel houses in terms of structural strength, thermal insulation, waterproofing, fire resistance, and sound insulation.
• Convenient Assembly and Disassembly: They have low disassembly and assembly losses and can be relocated quickly and easily, meeting the needs of different projects.
• Comfortable Living: Compared with tents, packing-box units can provide a stable, safe, and private indoor space. They can integrate standard doors, windows, lighting, and other facilities, and even be equipped with independent bathrooms. They can withstand harsh weather conditions and are suitable for projects that require a stable period of several months to several years. Although packing-box units and houses renovated from shipping containers share a similar concept, packing-box units are specially designed and manufactured, with more flexible dimensions.
