The Mobile Expandable Prefab House (19ft x 20ft) is a fold-out steel container home that opens on-site in hours, no crane required. Complete with a built-in toilet and shower, insulated wall panels, and a finished interior, it’s ready for use as temporary accommodation, a site office, guard house, or small residential unit. Rated for wind loads up to 70mph when properly anchored. Delivered flat-packed to a standard container footprint for easy transport, then expands to a full 19ft x 20ft (approx. 380 sq ft) living or working space.

Looking for an expandable prefab house that combines the durability of a shipping container with the space of a small home? Our 19ft x 20ft Mobile Expandable Prefab House with built-in bathroom is a factory-built, self-expanding steel structure that folds down to a standard container size for transport and unfolds on-site into a fully finished 19ft x 20ft (approx. 380 sq ft) living or working space — with a built-in toilet and shower already installed.
Unlike static prefab cabins that arrive as flat panels needing full on-site assembly, this expandable container house ships as one compact unit and opens out using its own folding frame, cutting installation time from weeks to hours.

The unit requires a solid, level foundation before expansion — do not install on soft ground, near snow drifts, or in areas prone to flooding or standing water. Legs should be anchored (drywall anchors/screws or concrete-set for best results) to maximise stability, particularly in higher wind areas. The house is not pre-wired: a qualified electrician should carry out all electrical connections to current UK wiring regulations before occupation.
