How to Calculate the Cost of Prefabricated Houses

The cost of prefabricated houses is typically calculated by multiplying the building area by the unit area cost, with the total price = building area × unit area cost. Specific costs are influenced by factors such as region, design complexity, supporting facilities, and brand premium.

I. Basic Cost Composition
The unit area cost of a prefabricated house includes expenses for structural components, transportation, assembly, and foundation construction. For example, the price of factory-prefabricated concrete wall panels may be as low as 300 yuan per square meter, but actual costs vary significantly due to regional policy differences. Taking Shanghai as an example, the government provides a subsidy of 100 yuan per square meter, while a similar house in Hangzhou may be 15% more expensive; in rural areas of Henan, the unit price of prefabricated houses is about 300 yuan per square meter, with a total price of approximately 60,000 to 80,000 yuan for a 200-square-meter house, including foundation structure, exterior wall insulation, and simple decoration.

II. Price Influencing Factors

1. Regional Differences: Land costs, transportation distances, and labor expenses directly affect the final price. In remote areas, the unit area cost may increase due to higher transportation costs. For example, in 2026, for Chinese modular buildings exported overseas, a prefabricated house with a selling price of 200,000 yuan has a factory price of only 100,000 to 120,000 yuan, with the rest being costs for packaging, sea freight, and insurance; after arrival at European and American ports, additional 'hidden construction costs' such as lifting fees, foundation construction fees, and water and electricity connection fees are incurred.
2. Design Complexity: Irregular structures, high-rise buildings, or special functional requirements (such as earthquake resistance and energy efficiency) increase the cost of custom components. For example, prefabricated houses meeting high earthquake resistance standards require more complex connection nodes and materials, resulting in a significantly higher unit price than ordinary structures.
3. Supporting Facilities: Value-added services such as pre-embedding of water and electricity pipelines and installation of doors and windows drive up the total price. If the house design includes integrated decoration (such as integrated bathrooms and kitchen modules), the unit area cost may increase by 20%-50%.
4. Brand Premium: Chinese prefabricated houses exported overseas may see their prices double after being marked up by local agents. For example, a certain brand's selling price in the European market is twice the factory price, mainly due to brand licensing, after-sales service, and market positioning differences.

III. Special Scenario Costs
Overseas projects need to additionally consider international transportation, tariffs, and localization adaptation costs. For example, prefabricated houses shipped to the Middle East require heat-resistant materials and adjustments to electrical standards to suit the local climate, and such customization requirements may increase the unit area cost by more than 30%.
