Description
Designed for buyers who need real floor space that can still be moved, the 40ft expandable folding house folds down to a narrow transport box and unfolds into a 73 m2 living unit. The wings are part of the steel structure, not an add-on, and they are lifted into place with the same crane that sets the unit down. Because the electrical system, the sandwich panels, the windows and the floor are fitted during production, the house is ready to use the moment the wings are locked and the power is connected.
The largest model in the range, the 40 ft unit opens to 73 m2 with three bedrooms, one living room, one kitchen and one bathroom for four to eight people. This version pairs white walls and black frames with a terrace along the front, which extends the living area outdoors and gives the building a residential, villa-like character. Eight double-glazed windows and 300 x 600 mm panel lighting are standard on this size, so even the deepest rooms stay bright.
Strength comes from a hot-dip galvanised steel frame built to national-standard sections. Side beams, end beams, columns and secondary beams are welded into one rigid box, and the folding wings hang on 130 mm galvanised hinges that are rated for repeated opening. Electrostatic powder coating plus an anti-corrosion layer protects the steel against rust, salt air and long-term UV exposure.
Thermal performance comes from 950-type EPS sandwich panels throughout: 65 mm on the external walls and the wing roofs, 50 mm on the main roof, the inner ceiling and the partition walls. An 18 mm glass magnesium floor deck covers the main body and the two wings, giving a solid base that can be finished with wood laminate, vinyl or tile according to the project.
