20ft Expandable Folding House Dark Grey with Black Frame

A 20ft expandable folding house solves a simple problem: a normal container is cheap to ship but too narrow to live in. This model keeps the container footprint for transport and widens itself on site, opening two wings to create roughly 37 m2 of interior. The whole conversion is mechanical - galvanised hinges, a locking wing frame and a sealed panel joint - so there is no wet trade, no curing time and no site waste, and the unit can be folded back and relocated whenever the project moves.

This version is finished in dark grey panels with black window and door frames, a restrained industrial look that works on construction sites, industrial yards, ports and mining camps as well as in modern urban settings. Dark grey shows less dirt and diesel film than light colours, which matters on working sites, and it pairs naturally with steel, glass and timber decking. For buyers ordering several units, this finish gives a uniform, professional appearance across a whole camp.

The structure is a fully galvanised national-standard steel frame. Top and bottom side beams, end beams and secondary beams form a closed box that carries the load of both wings, and 130 mm galvanised hinges take the movement of every fold. The frame is protected by electrostatic powder coating over an anti-corrosion coating, so the steel keeps its finish in coastal, humid and high-sunlight locations.

Walls, roof and partitions are 950-type EPS colour steel sandwich panels with 0.3 mm steel on both faces - 65 mm for the external walls and wing roofs, 50 mm for the roof, ceiling and partitions. The floor is an 18 mm glass magnesium board laid over the main frame and both wings, which stays flat and stable under furniture loads and resists moisture from below.
