The 40FT expandable container house is a large prefabricated modular home designed for customers who require more bedrooms, larger living areas, and greater flexibility in interior planning. After expansion, the house provides approximately 74 m² of usable floor space, making it suitable for permanent housing, holiday accommodation, rental projects, staff residences, and commercial modular building applications.
The house is manufactured and pre-assembled in the factory before shipment. Electrical wiring, plumbing, wall panels, flooring, windows, doors, kitchen cabinets, and bathroom equipment can be installed in advance according to the selected configuration.
After delivery, the building can be expanded and installed with lifting equipment, significantly reducing the amount of construction work required at the destination.

Flexible Residential Layout
The 40FT expandable container house provides enough space for a variety of residential and commercial floor plans.
Typical layouts may include:
• Three or four bedrooms
• One spacious living room
• One kitchen and dining area
• One or two bathrooms
• Laundry or utility room
• Storage space
• Office or study area
Customers may choose an open-plan living and kitchen area or separate the different functional zones with internal partition walls.
The number and location of bedrooms, bathrooms, doors, windows, and internal corridors can be customized according to the project requirements. The larger dimensions are particularly suitable for family housing, rental accommodation, holiday resorts, and long-term residential use.
Reinforced Steel Structure
The 40FT model uses a reinforced galvanized steel structure to support its larger dimensions and expanded floor area. The main frame is designed to provide structural stability during transportation, lifting, expansion, and long-term use.
The galvanized steel components offer improved corrosion resistance and help extend the service life of the building. Structural specifications can also be adjusted according to the local wind load, snow load, climate conditions, and applicable construction requirements.
Insulated Wall Panel Materials
A range of insulated wall panel materials is available, including:
• EPS sandwich panels
• Rock wool sandwich panels
• Polyurethane sandwich panels
• Graphene insulation panels
The wall panel system helps provide thermal insulation, wind resistance, and interior comfort.
For warm and moderate climates, EPS panels offer an economical and widely used solution. For projects requiring improved fire resistance, rock wool panels are recommended. Polyurethane and graphene panels can be selected for colder climates or projects requiring higher thermal insulation performance.
The interior and exterior wall panel thicknesses can be selected according to customer requirements.
Roof and Exterior Customization
The 40FT expandable container house is available with either a flat roof or a pitched roof.
A pitched roof can improve rainwater drainage and create a more traditional residential appearance. A flat roof provides a modern and simple architectural style and can also be combined with optional external roof structures or terrace designs.
Exterior customization options include:
• Black or white steel frame
• Standard colored sandwich panels
• Metal embossed decorative panels
• Glass curtain walls
• Large aluminum windows
• Sliding glass doors
• Customized entrance doors
• Multiple exterior colors and textures
Metal embossed panels are particularly suitable for customers who want a more durable and visually refined exterior finish. They provide additional protection against sunlight, rain, wind, and long-term outdoor exposure.
Glass curtain walls can be used in the living room or front façade to increase daylight and create a more open interior atmosphere.
