Dimensions and Comfort of the 30ft Expandable Container House
Unlike traditional containers, the 30ft expandable container house can unfold into a spacious living area. When expanded, it provides approximately 74–80 square meters of usable space, depending on the design. This makes it comparable in comfort to a small apartment, with enough room to accommodate:
- A living room with sofa and TV space;
- Two bedrooms with proper ventilation;
- A kitchen and dining area;
- A bathroom with modern fittings;
The clever folding and sliding wall design ensures that while compact in transport, it expands into a full-size living space, creating an ideal balance between portability and comfort.
In addition to the 30-foot expandable container house, YG also offers foldable houses in various sizes, including 10-foot, 20-foot, and 40-foot expandable container houses. These foldable houses of varying sizes can meet diverse needs, including family living, construction site dormitories, offices, and vacation homes. You can flexibly choose a house based on your project size and budget.
