Expandable Folding Container House

The mobile expandable container home with bathroom and kitchen is a fully self-contained, fold-out living solution that transforms from a compact shipping module into a spacious dwelling in minutes . Built on a heavy-duty galvanized steel frame with Q235B construction, these units offer exceptional durability, wind resistance up to grade 11, and seismic protection to grade 8 . Available in 10ft,20ft, 30ft, and 40ft configurations, each unit arrives with pre-installed electrical wiring, plumbing systems, insulated sandwich panel walls, and a complete bathroom and kitchen setup . The fold-out expansion mechanism extends usable floor area from as little as 12 square meters to over 37 square meters in the 20ft model, with 40ft versions offering up to 72 square meters of living space .

Customization options allow for varied layouts, color choices, and additional features such as air conditioning or heating systems.

Versatile Applications

Perfect for family guest houses, remote worker accommodations, construction site offices, emergency shelters, or vacation cabins, these mobile homes provide a flexible housing solution that can be relocated as needs change . The robust steel frame supports stacking up to three stories high, enabling multi-unit configurations for larger family needs or commercial applications .
