Product Overview
The expandable container house in 20ft and 40ft versions gives you full-size living space that ships at folded-container cost. On site, the side walls fold down to triple the floor area in a few hours.
The galvanized steel frame carries 50–125 mm sandwich panel walls for real insulation, and the interior arrives with wiring, lighting and sanitary fittings pre-installed — connect services and move in.

Frequently Asked Questions
Which size should I choose, 20ft or 40ft?
The 20ft model suits single-room offices and cabins; the 40ft model offers a larger multi-room layout for dormitories and family use. Both ship in standard container slots.
How long is installation?
A 20ft or 40ft unit unfolds and is weather-tight within several hours; full interior setup is usually completed in one day.
What is the MOQ?
MOQ is 1 set. Multi-unit camp projects receive volume pricing and staggered delivery schedules.
Can it be relocated after use?
Yes — the unit folds back to shipping configuration and can be craned onto a truck for relocation, a key advantage for construction camps.
What is the lead time?
Typically 15–30 working days after order confirmation depending on quantity and customization.
