Single-Story Prefabricated House

Single-story prefabricated houses are constructed by assembling building components produced through industrial manufacturing methods, which are prefabricated in factories and then transported to the site for assembly.

I. Technical Types and Component Composition
Single-story prefabricated houses primarily employ two technical systems: prefabricated concrete structures and steel structures. Their core components include prefabricated products such as beams, slabs, walls, and columns, which are produced in factories using standardized molds and automated equipment to ensure dimensional accuracy and structural strength. For example, the prefabricated houses popular in rural areas of Henan Province adopt a fully reinforced concrete structure, with the reinforced concrete frame prefabricated in factories and then hoisted and assembled on-site to complete the main structure.

II. Construction Advantages and Performance Characteristics

1. Quality Controllability: The unified factory production model eliminates human errors in on-site construction, with component strength, durability, and other indicators guaranteed through both laboratory testing and on-site sampling inspections. For instance, the warranty period for prefabricated houses in Henan reaches 70 years, significantly exceeding that of traditional brick-and-mortar structures.
2. Environmental Protection and Cost-Effectiveness: The use of new environmentally friendly materials such as recycled aggregate concrete results in a disassembly and recycling rate of over 80% for components. The cost per square meter is approximately 300 yuan, 15%-20% lower than that of traditional buildings, and material waste is reduced through modular design.
3. Efficiency Improvement: On-site construction time is significantly shortened. In the Henan case, hoisting a single house takes only 2-4 hours, with modular construction speeds 50%-70% faster than traditional methods. Electrical and water pipelines can be pre-embedded within prefabricated wall panels, avoiding secondary trenching.
4. Customization Flexibility: By adjusting the dimensions and combination methods of prefabricated modules, functional partitions such as bedrooms and kitchens can be quickly customized to meet individual needs.

III. Market Applications and Development Trends
There is strong demand for prefabricated houses from China in overseas markets, with export value in the Guangzhou Customs area increasing by 38.1% year-on-year in the first four months of 2026. In European and American markets, due to high labor costs (e.g., approximately $25 per hour for construction workers in the United States) and housing shortages (e.g., the European Union is expected to face a shortage of 3 million housing units by 2025), acceptance of cost-effective prefabricated houses continues to rise. The domestic market focuses on rural revitalization, with over 100,000 prefabricated rural houses built in Henan, Shandong, and other regions, forming a replicable model of industrialized housing construction.
