Prefabricated House Cost Budget Table

The cost budget for prefabricated houses varies depending on the structural type. Below are the specific classifications and budget ranges:

1. Light Steel Structure Prefabricated Houses Light steel structures use steel as the main load-bearing frame, characterized by light weight, short construction period, and strong earthquake resistance. The cost range is 1500-2500 yuan/㎡. This structure is suitable for low-rise residences, vacation villas, and other scenarios, with cost advantages mainly reflected in material transportation and on-site assembly efficiency. If the foundation conditions are good and the construction environment is simple, the budget can approach the lower limit; if complex foundation treatment or high-rise design is required, costs may increase.

2. Wood Structure Prefabricated Houses Wood structures use natural wood or engineered wood products as the framework, emphasizing environmental protection and natural integration, commonly found in Nordic and North American regions. The cost range is 2000-3500 yuan/㎡. Cost differences mainly depend on the type of wood (such as pine, oak), anti-corrosion treatment processes, and decoration requirements. For example, when using imported high-grade wood or complex roof designs, the budget may approach the upper limit. Additionally, wood structures have higher requirements for fire and insect prevention treatments, requiring additional reserved expenses.

3. Concrete Structure Prefabricated Houses Concrete structures are assembled on-site using prefabricated wall panels, floor slabs, and other components, combining industrial efficiency with structural stability, suitable for multi-story residences or commercial buildings. The cost range is 3000-4000 yuan/㎡. In the cost composition, the precision of component production, rental of lifting equipment, and joint treatment processes are key factors. If using prefabricated concrete technology (such as PC components), construction periods can be shortened but mold costs will increase; if on-site pouring is combined with prefabrication, costs may further rise.

4. Special Type Cement Prefabricated Houses These houses are characterized by low cost and rapid construction, commonly found in temporary housing, construction site dormitories, and other scenarios. The budget is 200-600 yuan/㎡. Cost differences are mainly determined by material thickness and functional configurations (such as doors, windows, insulation layers). For example, single-layer thin-walled cement houses have budgets close to the lower limit, while houses with thickened walls or equipped with basic water and electricity require higher expenses. It should be noted that the durability and comfort of these houses are generally lower than those of the first three structural types.

Common Factors Affecting Costs In addition to structural types, actual costs are also influenced by the following factors:

• Regional Freight: Material transportation costs in remote areas may increase by 10%-20%;
• Construction Difficulty: Sites with complex terrain or limited space require additional mechanical shift fees;
• Foundation Costs: Soft soil foundations require pile foundation treatment, with costs possibly exceeding 30% of the total budget.

It is recommended to comprehensively select the structural type based on project requirements, budget, and usage scenarios, and consult professional institutions in advance for refined calculations.
