The expandable house, often referred to as a double-wing or "butterfly" container home, represents a breakthrough in prefabricated housing technology. Unlike standard fixed-size containers that offer limited interior volume, this innovative system utilizes a high-precision folding mechanism that allows the structure to expand nearly 3 times larger than its original transport footprint. By balancing compact logistics with spacious on-site living, the expandable house provides a truly "turnkey" solution for modern living, office, or commercial needs.

The core innovation lies in its structural versatility: when folded, the unit maintains a standard 2.2m width, making it compatible with global shipping and handling systems. Once it reaches its destination, the two side wings unfold to create a massive interior—up to 37㎡ for a 20ft unit and 74㎡ for a 40ft unit. This design ensures that you don't increase the overall shipping weight or complexity, yet you gain a vast, functional environment that feels more like a permanent building than a temporary container.

What sets our expandable house apart is the level of factory integration. These are high-performance plug-and-play modular homes designed to minimize on-site labor. Every unit is delivered with essential utilities pre-installed, including:

• Integrated Utilities: Fully pre-wired electrical circuits and pre-plumbed water systems that meet international safety standards.
• Pre-Finished Interiors: High-quality 18mm fiber cement or bamboo plywood flooring covered with premium PVC finishes.
• Full Sanitary Facilities: A standard configuration includes a complete bathroom with a toilet, shower, vanity, and drainage system, all pre-installed and tested.
• Bespoke Layouts: Flexible partitioning that allows for customized living rooms, kitchens, and up to three bedrooms to suit your specific lifestyle or project requirements.

To ensure every expandable house we supply meets the rigorous demands of global projects, we adhere to high-performance engineering standards. From structural integrity to thermal efficiency, these metrics define the quality of our modular solutions:

• Structural Lifespan: Designed for long-term durability, our units have a service life of 15 to 20+ years depending on the environmental conditions.
• Expansion Efficiency: Our innovative folding system allows for a rapid setup where a standard unit can be fully unfolded in just 10 to 15 minutes.
• Logistics Optimization: To minimize international freight costs, a single 40ft HQ shipping container can efficiently transport 2 sets of 20ft expandable units.
• Wind & Seismic Resistance: The reinforced galvanized steel skeleton is engineered to withstand up to Grade 10 to 11 wind loads and Grade 8 seismic activity.
• Fire Safety Standards: We utilize Class A non-combustible insulation materials, such as Rock Wool, providing up to 120 minutes of fire resistance.
• Space Utilization: The unique "3-in-1" design expands the living area from a 2.2m transport width to a massive 6.3m functional width, nearly tripling the usable space.
• Thermal Performance: Equipped with high-density sandwich panels and double-glazed windows, our houses maintain interior comfort across all 4 seasons.
