Prefabricated Concrete Homestay House

Prefabricated concrete homestay houses, built using prefabricated reinforced concrete modules through factory production and modular assembly, are becoming a popular choice for rural self-built houses, commercial spaces, and cultural tourism projects (such as homestays).

Technical Principles

The core of prefabricated concrete homestay houses lies in "factory prefabrication + on-site assembly." In specialized production bases, core components such as walls, floors, and beams are cast in one piece using high-precision molds. Each module integrates multiple structures, including steel reinforcement skeletons, insulation layers, waterproof layers, and pre-embedded pipelines, allowing for flexible combination like "building blocks." This approach enables standardized production of building components, reducing the complexity and uncertainty of on-site construction.

Advantages and Characteristics

1. High Efficiency: A single 30㎡ module takes only 7 days to prefabricate in the factory. After being transported to the site, three workers with a crane can complete the installation of a single module in 4 hours. A 100㎡ house can be fully assembled in just 2 days, significantly shortening the construction period.
2. Low Cost: Taking a 120㎡ rural self-built house as an example, the cost of a traditional brick-and-mortar structure is approximately 180,000-220,000 yuan (including labor), while the cost of the main concrete modules is only 120,000-150,000 yuan. With interior and exterior decoration, the total cost can be controlled within 200,000 yuan, reducing the overall cost by 30%. If a leasing model is chosen, the annual rent can be as low as 5,000 yuan per room, further reducing initial investment.
3. Green and Environmentally Friendly: Factory production is fully controllable, with a 95% recycling rate for offcuts. There is no dust or sewage discharge on the construction site, and construction waste is only 10% of that from traditional construction. Environmentally friendly concrete and water-based paints are used, with formaldehyde emissions ≤0.05mg/m³, far below the national standard (0.1mg/m³), enabling "immediate occupancy" upon completion.
4. Stable Performance: Using C30-C40 grade concrete with built-in Φ8-Φ12 steel reinforcement mesh, the compressive strength reaches 25-30MPa, 1.5 times that of traditional brick-and-mortar structures. The walls have pre-reserved slots for EPS insulation layers, which, when inserted on-site, improve thermal insulation by 40%, providing significant warmth in winter and coolness in summer. The modules are connected using pre-stressed bolts and welded steel plates, forming an integrated frame with a wind resistance rating of 10 and a seismic fortification intensity of 7 degrees (equivalent to the destructive force of the Wenchuan earthquake).
5. Flexible Space: The standard module size is 6m×3m×3m (length, width, height). Horizontal splicing and vertical stacking (up to 3 floors) allow for flexible户型 designs. For example, three modules can be combined to form a 90㎡ two-bedroom, one-living room rural self-built house with an independent kitchen and bathroom; six modules can be combined to create a 180㎡ LOFT-style cultural tourism homestay with a large terrace and floor-to-ceiling windows.

Price Reference

Prices vary among different suppliers. For example, the price of a prefabricated concrete house in Jining, Shandong, is 7,798 yuan; Hebei Zhongzhu Housing Technology Co., Ltd. offers planning, design, and construction services for assembled concrete homestay houses starting at 1,100.00 yuan per square meter.
