Single-Story Prefabricated House
A single-story prefabricated house is a type of dwelling constructed primarily from prefabricated components, characterized by modular design and efficient construction. Below is an overview of its structural types, materials, safety, pricing, and market trends:
Structural Types and Materials
The core components of a single-story prefabricated house are prefabricated panels, available in solid and hollow types, both made from factory-produced cement. Additionally, material options include steel structures, concrete, and wood, with steel and concrete being widely used in Chinese enterprises due to their high strength and durability. For example, CMC composite modular buildings significantly enhance seismic resistance through integrated steel-concrete pouring techniques.
Construction Methods and Advantages
Prefabricated houses adopt a modular design, with components standardized in factories and assembled on-site, reducing construction time by over 30% compared to traditional buildings. This “factory-made” approach unifies industrial standards, digital precision, and automation efficiency, minimizing on-site wet work and human errors while reducing environmental impact. For instance, light-steel prefabricated buildings offer one-stop services covering design, installation, and full-package contracting, further streamlining the process.
Safety and Hidden Risk Identification
House safety requires evaluation based on construction standards, material quality, and usage conditions. Potential risks include:
- Structural integrity: Foundation settlement, house tilting, or loose connections between prefabricated panels and load-bearing walls may lead to structural instability;
- Component condition: Cracks, deformation, or steel reinforcement corrosion can weaken load-bearing capacity;
- Usage and modifications: Unauthorized removal of load-bearing walls or illegal additions may compromise original design safety factors.
Inspection recommendations: Regularly check connection nodes, component surfaces, and usage environments, avoiding overloading or structural alterations.
Market Pricing and Availability
Prices vary significantly based on materials, region, and configuration:
- Prefabricated cement houses: Approximately 300–350 RMB/m² in Zhumadian, Henan; custom cement mobile homes cost around 3,980 RMB/set in Chengde, Hebei;
- Light-steel prefabricated buildings: Priced at approximately 1,000–1,280 RMB/m², including full-process services like design and installation.
Policies and Market Trends
Since 2022, China has implemented renovation policies for prefabricated panel houses, focusing on repairs and upgrades while demolishing only buildings meeting hazardous criteria. Meanwhile, exports of prefabricated houses have surged: In the first four months of 2026, enterprises in Guangzhou Customs’ jurisdiction exported 1.4 billion RMB worth of mobile homes (+38.1% YoY), while Shenzhen Port exported 1.68 billion RMB (+19.6% YoY), reflecting growing international demand for modular construction.
