20foot 720mm Expandable Living Space

The 20foot 720mm Expandable Living Space is a precision-engineered modular housing unit that combines the portability of a 20-foot container with the flexibility of a 720mm expandable design, offering a smart balance between compact storage/transport and spacious living. Tailored for both temporary and semi-permanent use, this expandable unit addresses the pain point of limited space in portable housing, transforming from a standard 20-foot  compact unit to a roomier living space with a 720mm lateral expansion on one or both sides—effectively increasing interior area without sacrificing mobility.

At the core of its design is the 720mm expandable mechanism, which is smooth, sturdy and easy to operate. Constructed with high-strength galvanized steel frames, the expansion structure ensures stability and load-bearing capacity even when fully extended, capable of withstanding daily use and mild harsh weather conditions. The 20-foot base size adheres to standard shipping container dimensions, allowing convenient transportation by truck, ship or train—no special logistics required—while the 720mm expansion adds valuable living space, making it suitable for small families, construction workers, remote workers or vacationers.

Durability and comfort are integrated into every detail. The exterior is coated with anti-corrosion, anti-rust and waterproof paint, extending the unit’s service life to 15-20 years with proper maintenance. Wall panels are filled with high-density thermal insulation material, paired with sealed doors and double-glazed energy-efficient windows, ensuring excellent thermal insulation and soundproofing. When expanded, the 720mm extra width creates room for a separated sleeping area, a compact kitchenette, a functional bathroom and a small living space—accommodating 2-4 people comfortably without feeling cramped.

The expansion process is efficient and labor-saving, requiring only 2-3 workers and basic tools to complete within 1-2 hours. When not in use or needing relocation, the unit can be easily collapsed back to its original 20-foot size, reducing storage and transportation costs significantly. Additionally, the interior can be customized according to specific needs, with optional fittings such as built-in storage cabinets, bunk beds, induction cookers and water heaters, adapting to diverse living requirements.

This 20foot 720mm Expandable Living Space is an environmentally friendly and cost-effective solution. Its factory prefabrication reduces on-site construction waste by over 80% compared to traditional housing, and most components are reusable and recyclable. It is widely applicable to construction site dormitories, remote work camps, disaster relief shelters, vacation cabins and temporary residences. By combining standard portability with a practical 720mm expansion, it redefines flexible living, offering a compact-yet-spacious option for modern mobility and space needs.
