The Grande prefab foldable house can be installed in less than an hour, supports customization, and has a complete plumbing and electrical system.

The 20ft prefab foldable house features a sleek rectangular structure with a strong black steel frame and white insulated wall panels, giving it a modern and durable appearance. Large glass sliding doors and wide windows provide natural light and ventilation, while smaller side windows add functionality and privacy. Its foldable design makes it compact for transport and quick to set up.
A Durable Galvanized Steel Frame
The prefab foldable house structure is built with 2.5 mm galvanized square steel tubes. The roof uses 2×5 beams, and the base is reinforced with 9 beams, giving the house a stable foundation even in demanding environments. The white spray paint finish adds a clean look while protecting the frame against rust. For the exterior, the walls use metal carved panels with a 75 mm EPS sandwich core, which is thicker and more efficient than the 50 mm panels often used by competitors.

What Comes Standard
Each unit is delivered as a complete house, not just a shell.
- Walls: EPS sandwich panels, 75mm thick
- Flooring: Structural board covered with PVC flooring
- Windows & Doors: Plastic-steel windows and a steel security door
- Bathroom: A dry and wet separated layout with a sink, mirror, toilet, and shower
- Pipes: Integrated hot water, cold water, and sewage systems
- Electrical system: LED lighting, power sockets, switches, air switch, distribution box, and CEE industrial plug
All components meet European and American safety standards, ensuring the house is ready for global use.
Practical Bathroom Design
A standout feature of the prefab foldable house is the separated bathroom, designed to keep the shower area isolated from the dry zone. This reduces moisture, extends durability, and makes daily living more comfortable—an important detail for long-term use.
Flexible Layouts and Customisation
The prefab foldable house is not limited to one standard model. Customers can choose from layouts ranging from a single room with one bathroom to four rooms with two bathrooms. The color of the panels, the type of materials, the placement of windows and doors, and even the style of the internal partitions can be customized. This flexibility makes the foldable house suitable for very different needs, whether as a worker dormitory, a family home, or a small office.

Quick Build—One-Hour Installation
Speed is one of the biggest advantages. With four workers, one unit can be unfolded and assembled in about an hour. Everything is already in place: the frame, the walls, the flooring, the windows, the doors, and the wiring. This makes it ideal for projects where time is limited, such as emergency shelters or rapidly expanding work sites.

Affordable and Comfortable
Compared with buying or building a traditional house, the cost of a prefab foldable house is only a fraction. Yet, the comfort level is very close to that of a permanent building. This balance of low price and livability is why many construction companies and local governments choose Grande houses for large-scale projects.
Easy to Transport and Relocate
The houses are designed with logistics in mind. A 40HQ high-cube shipping container can carry two prefab foldable houses, reducing freight costs. Because they are foldable, they save warehouse space and can be shipped quickly from stock. Once on-site, they can be moved again if needed, making them highly practical for mobile projects.

Built for Extreme Environments
Grande prefab foldable houses have been tested in challenging climates:
- Heat resistance: Sandwich wall panels (steel + rock wool + fireproof board) keep indoor temperatures up to 18°C cooler. Field tests in Africa and the Middle East showed summer indoor temperatures staying below 28°C.
- Earthquake and wind resistance: Independent tests confirmed the houses withstand 8.0 magnitude earthquakes and 17-grade wind pressure, keeping displacement within 3mm.
- Cold and high-altitude performance: In Tibet at 5000 m altitude, houses showed zero frost damage. Materials perform reliably from -30°C to 70°C.
Sustainability and Green Building
Grande houses are built with sustainability in mind.
- Recyclability: 90% of components can be reused, and rock wool insulation has a 75% degradability rate.
- Certifications: The products meet EU CE and EPD environmental standards.
- Low carbon solutions: With integrated solar panels, one unit can generate around 3000 kWh annually, cutting carbon emissions by 60%. Smart water systems have reduced water use by 50% in projects such as worker camps in Argentina.
