300% Usable Space
Ships in a standard container width and unfolds dual side wings on site, delivering up to 37 sqm (20ft) or 72 sqm (40ft) of clear interior space.
Transformative Modular Architecture
Triple-Width Expansion System for Rapid B2B Deployment
The NuPON Expandable Container House is an advanced dual-wing folding modular structure designed to ship as a compact standard ISO footprint and unfold into a spacious living unit in under 30 minutes.
Built with heavy-gauge hot-dip galvanized steel frames and high-performance sandwich insulation panels, each module delivers immediate structural rigidity, superior thermal insulation, and complete weatherproofing. The entire unit comes factory-integrated with pre-wired electrical circuits, plumbing provisions, windows, and lockable security doors.
- Expands up to 3× its transported shipping size
- Heavy-duty galvanized steel structural chassis
- Factory pre-installed wiring, ceiling & flooring
- Typhoon-tested seal joints & zero rain leakage
- Relocatable as a single unified structure
- Customizable 1 to 3 bedroom floor plans

Procurement FAQ
Frequently Asked Questions
Direct answers from our engineering desk regarding international procurement, freight, and technical submittals.
An expandable container house is a factory-prefabricated modular building featuring a central structural core and two fold-out side wings. Transported in a compact ISO container footprint, the unit unfolds on site via heavy-duty hinges and mechanical leverage to deliver up to three times its shipping floor area in less than 30 minutes.
Typically, two complete 20ft expandable container units (folded to package dimensions of 2200 x 5900 x 2480 mm) fit into a single 40ft High Cube (HQ) shipping container, drastically lowering ocean freight cost per square metre.
Yes. Constructed with 150x150mm hot-dip galvanized steel columns, reinforced main beams, and interlocking sandwich panels, units are engineered to sustain wind loads up to typhoon scale 11-12 and withstand regional seismic forces.
Yes, all electrical wiring, breaker panels, light switches, and wall sockets are pre-installed according to client destination requirements (CE, UL, BS, or AU/NZS standards; 110V/220V/240V configurations).
