Product Description

40FT Expandable Container House | Side Fold-Out Design with Reinforced Steel Frame and Insulated Panels

The 40FT expandable container house delivers 73 m² of fully enclosed living or working space from a single unit that ships folded to standard 40FT road and sea transport dimensions. The side fold-out expansion system deploys without cranes or specialist contractors — two workers complete the full unfolding and lock-in sequence in under two hours. Built on a hot-dip galvanized Q345B structural steel frame with welded primary joints and bolted secondary connections, the unit maintains rigid box integrity under wind load, transport vibration, and repeated relocation cycles. Insulated sandwich panel walls and roof deliver year-round thermal comfort across tropical, temperate, and cold-climate deployment zones.

Why the 40FT Model At 73 m² expanded floor area and 5.3 tons net weight, the 40FT unit is the largest single-piece expandable house in this product range. It provides enough space for a two-bedroom residential layout with kitchen and bathroom, a full project office with meeting room and reception, or a combined dormitory and utility block for up to eight occupants — all delivered in one shipment, one piece, requiring no on-site structural work.

Frequently Asked Questions

Does deploying the 40FT unit require a crane or heavy equipment?

No crane is needed for the expansion sequence. Two workers can unfold and lock both side wings using the built-in mechanical locking pin system in 90 to 120 minutes. A forklift or crane is only required to offload the unit from the delivery truck and position it on the prepared ground surface.

What floor plan configurations are available for the 73 m² interior?

The 73 m² expanded area supports a wide range of layouts. Common configurations include a two-bedroom residence with kitchen and bathroom, a project office with reception and two private rooms, an eight-bed dormitory with utility room, and a combined living and office space. Custom partitioning plans can be provided based on your specific use case.

Which wall panel type is recommended for hot climates versus cold climates?

For hot and tropical climates, 100mm EPS panels combined with a reflective exterior color coating and ventilated roof design provide effective heat reduction at a lower unit cost. For cold climates or year-round four-season use, 150mm rock wool panels are recommended — they deliver superior thermal resistance (U-value ≤ 0.30 W/m²K) and Class A1 fire performance, which is required for permanent-style residential placement in many jurisdictions.

Can the unit be relocated to a new site after initial deployment?

Yes. The fold-out expansion reverses fully — the side wings fold back in and lock for transport. The folded unit can be loaded onto a flatbed truck using a crane or telehandler and shipped to a new destination. Most units withstand five or more full relocation cycles without structural degradation when handled to standard lifting guidelines.

What information is needed to receive a quotation for the 40FT model?

Please provide your destination port, required quantity, intended use and floor plan preference, wall panel type (EPS, rock wool, or PU), electrical voltage standard, and any optional fitout requirements such as bathroom module, kitchen cabinetry, air conditioning brackets, or furniture packages. A detailed FOB quotation will be issued within 24 hours.
