Product Overview
The double-wing expandable container house opens on both sides — two folding wings double or triple the interior area from a single transport footprint. Assembly and disassembly are quick, so the unit can move between projects instead of being demolished.
The structure combines high-strength aluminium-alloy frames with eco-friendly composite panels: lighter than a full steel box, durable in outdoor use, and recyclable at end of life — a fit for eco resorts and relief programs alike.

Frequently Asked Questions
What makes the double-wing design different?
Both side walls fold out (not just one), giving a much larger floor area from the same transport footprint — ideal where shipping cost dominates the budget.
How long does assembly take?
The wings unfold and the unit is weather-tight within hours; internal fittings are factory-installed, so same-day occupancy is normal.
Can the house be disassembled and reused?
Yes. The folding design allows repeated assembly/disassembly and relocation — suitable for rental fleets and relief programs.
Is it suitable for permanent living?
With 50–125 mm insulation options and a 25–30 year structure, it supports both permanent and temporary use depending on your configuration.
What is the MOQ and lead time?
MOQ is 1 set; typical lead time is 15–30 working days after order confirmation.
