20ft double-wing model
20ft Expandable Container House
The standard 20ft model balances a 37 m² listed footprint with a two-unit-per-40HQ loading reference. Review the verified base schedule before defining the interior package.
Standard-width 20ft model
37 m² from a 5.9 m-long folded unit
This model keeps the 5,900 mm transport length of the 20ft range, folds to 2,200 mm wide and opens to a 6,300 mm overall width. Its listed 37 m² footprint sits between the narrower 700 mm-folded model and the longer 30ft model.
The standard schedule lists one living room, reference occupancy for 2–4 people and two folded units per 40 ft high-cube container. Use these figures as the selection baseline; furniture, kitchen and bathroom fit-out must be defined in the quotation.
