Short answer

Expandable container houses deliver more floor area per shipped unit than flat pack houses because they unfold on site, but flat pack units are cheaper per square metre and require more labour to assemble. Choose expandable for fast deployment and space; choose flat pack for cost-sensitive projects with available labour.

Units that fit this question

20FT Double Wing Expandable Container House (Metal Carved Panel)

Both long side walls unfold to double the floor area; metal carved panel facade and complete interior.

20FT Expandable Container House

A 20ft module that opens on site into a 35 m² studio or one-bedroom unit — finished interior, one day to commission, one container slot to ship.

40FT Flat Pack Container House

A 40ft flat pack module that ships knocked down and gives a 29 m² open floor plate — the standard choice for canteens, recreation rooms and open-plan site offices.
