Prefabricated House Finished Large Open Space

Currently, no standardized products or fixed prices for 'prefabricated house finished large open space' have been directly retrieved, but large open-space structures can be achieved through modular prefabricated house expansion solutions, with specific costs depending on materials, configurations, and transportation.

I. Technical Paths for Achieving Large Open Spaces in Prefabricated Houses

Large open-space structures in prefabricated houses are typically realized through modular expansion. For example, container houses or light steel modules can be combined through splicing to form large spaces:

• Container Modules: A standard 20-foot container covers approximately 37 square meters, while a 40-foot container covers about 70 square meters. Multiple containers can be spliced horizontally or vertically to create even larger open spaces.
• Light Steel Modules: These utilize a light steel structural frame, with walls, roofs, and other components prefabricated in the factory. During on-site assembly, the spatial layout can be flexibly adjusted, making them suitable for customized large open-space requirements.

II. Case References for Prefabricated Houses

1. Amazon Spain Prefabricated Houses: These offer adjustable floor plans ranging from 1 to 6 rooms, with the base model starting at 8,279 euros (approximately 64,000 RMB). They include kitchens, bathrooms, and pre-installed plumbing and electrical systems, but homeowners are responsible for external water and electricity connections. Although not directly labeled as 'large open spaces,' these houses can achieve open layouts by reducing internal partitions.
2. Chinese Export Prefabricated Houses: These employ Modular Integrated Construction (MIC) technology, with all components prefabricated in the factory and rapidly assembled on-site. For instance, an Australian mining camp achieved low-cost large spaces through module splicing, and a 12-story apartment building in the Philippines was constructed in just 9 days using MIC technology, demonstrating the scalability advantages of modular prefabricated houses.
3. Domestic Wholesale Market Cases:
   • Guangdong Guose Modular Construction Co., Ltd.'s 27-square-meter light steel villa, priced at 188 RMB per square meter, can be expanded by adding more modules.
   • Ganzhiju Integrated Housing (Jiangsu) Co., Ltd.'s 318-square-meter container steel structure house, priced at 270.75 RMB per square meter, is suitable for large open-space needs.
   • Anhui Richuang Construction Engineering Co., Ltd.'s 24-square-meter movable prefab house, priced at 79.2 RMB per square meter, can achieve low-cost expansion through splicing despite its smaller size.

III. Factors Influencing Pricing

The final price of a large open-space prefabricated house depends on the following factors:

• Materials: Container houses are primarily steel-based, while light steel modules use a light steel frame with insulation materials. Different materials affect costs.
• Configurations: Whether internal finishes, plumbing and electrical systems, doors, and windows are included.
• Transportation Costs: Larger modules and longer transportation distances result in higher fees.
• Customization Requirements: Special dimensions or functions (e.g., earthquake resistance, insulation) may increase costs.

For specific solutions, it is recommended to contact prefabricated house suppliers for design drawings and quotation lists.
