Frequently Asked Questions (FAQ)

How long does it take to fold and expand the Model-700?

A: With 2 workers, on-site expansion takes only 3 hours, and folding takes 2 hours. The process is simple and requires no professional equipment—manual operation is available, and an electric hydraulic system can be customized for even easier, more efficient operation.

Is a building permit required?

A: Permit requirements vary by country and region. As a temporary or semi-permanent prefab house, it usually requires simpler approval procedures than traditional buildings. We provide complete technical drawings and certification documents to help you quickly apply for local permits.

Can the Model-700 unit be relocated after installation?

A: Yes. It features a removable and foldable structure, allowing it to be folded back into a compact size after disassembly, transported to a new site, and reinstalled. It can be reused ≥8 times without structural damage, making it highly suitable for mobile use needs.

What is the warranty period?

A: We provide a 12-year warranty for the galvanized steel frame, a 1-year warranty for electrical and plumbing accessories, and lifetime technical support.

Can I customize the interior layout?

A: Absolutely. We offer comprehensive customization services, including interior layout (1-bed, office, mixed-use), exterior color, wall/roof materials, windows/doors style, and additional functions (such as solar panels), to fully meet your specific project needs.
