Narrow Mobile Expandable Container House - Eco-Friendly & Rapid Assembly
Definition & Core Concept
Narrow Expandable Container House is a prefabricated steel structure modular building. It consists of a central fixed cabin with single or double side fold-out wing cabins. When folded for transportation, its width is only 0.70 meters, much narrower than the standard 2.4-meter-wide container, and 6 units can be loaded into one 40ft high cube container. After on-site horizontal expansion, the width reaches 4.8 meters, with the usable area increased by 2 to 3 times, perfectly combining compact transportation size and practical living space. Featuring narrow-width transport, on-site expansion, full pre-furnishing, low cost and high flexibility, it serves as an ideal modular housing solution for cross-border export, construction on narrow sites and temporary accommodation.
Main Components & Functionality
1. Factory Pre-fabrication
- Frame Fabrication: Weld steel structures to form the central main cabin and foldable wing cabins. Conduct anti-corrosion, rust-proofing and surface painting treatment.
- Wall Installation: Mount fireproof & thermal insulation sandwich panels and exterior claddings, and complete waterproofing and sealing work.
- Interior Completion: Pre-install doors, windows, flooring, ceiling, kitchen & sanitary facilities, water & electrical pipelines, lights and switches for full interior finishing.
- Mechanism Commissioning: Assemble manual/hydraulic expansion systems and locking parts. Test folding and expanding repeatedly to ensure stable operation.
- Fold & Lock: Fold the wing cabins inward and fasten all locks to switch to narrow transport mode, then conduct factory inspection.
2. Logistics & Transportation
- Loading: Load the folded units (0.7m width) into 40ft HC container, 6 units per container.
- Delivery: Transport goods to destination via sea or land freight.
- Unloading: Unload units with cranes or forklifts and transfer to the construction site.
3. On-site Deployment & Installation
- Site Preparation: Clear and level the ground. Lay simple concrete foundation or support bases as required.
- Positioning: Hoist the folded house to the designated position and level it accurately.
- Unlock & Expand: Release transport locks, then expand the wing cabins manually or hydraulically to full size.
- Reinforcement: Fasten all connecting joints, support legs and locking devices to strengthen the overall structure.
- Connection & Commissioning: Connect external water and power supply. Inspect pipelines, electrical systems and functional facilities.
- Handover: The house is ready for use after final acceptance.
Key Advantages
- Low transportation cost & high loading capacity
Folded width is only 0.7m. Up to 6 units can be loaded in one 40ft HC container, which greatly cuts down sea and land freight costs for export.
- Excellent site adaptability
The compact folded design allows access to narrow lanes, mountain areas, scenic spots and confined yards where standard containers cannot reach.
- High space efficiency
After expansion, the width reaches 4.8m and the usable area increases 2 to 3 times, balancing easy transportation and comfortable living space.
- Fast installation & labor saving
Fully prefabricated with complete interior and utilities. It can be expanded manually or hydraulically by only 2–3 workers without heavy machinery, and ready for use within hours.
- Stable structure & reliable performance
Built with steel frame and fireproof & thermal insulation sandwich panels. It features excellent wind resistance, earthquake resistance, waterproofing and heat preservation, suitable for various climates with long service life.
- High mobility & reusability
The unit can be folded, expanded, hoisted and relocated repeatedly. It is widely used for temporary accommodation, resort homestays, site dormitories, field offices and other purposes.
- Fully pre-furnished delivery
Doors, windows, water and electrical systems are all pre-installed in factory. Simply connect external utilities for immediate occupancy.
Common Applications
- Tourism & Resort: Vacation houses, glamping cabins, homestays
- Construction Site: Dormitories, temporary offices, guard rooms
- Emergency Use: Disaster shelters & emergency accommodation
- Rural & Courtyard: Guest rooms and auxiliary buildings
- Commercial Use: Mobile shops, service stations, exhibition booths
- Field Work: On-site offices and staff quarters for outdoor operations
