Technical Specifications & General Configuration

The 40FT Double Wing Expandable Container House is designed to combine compact transportation with spacious living. In transport mode, the folded size is 11,800 × 2,200 × 2,500 mm, allowing efficient containerized shipping. Once fully deployed, the unit expands to approximately 11,800 × 6,300 × 2,500 mm, providing a usable living area of around 65–75 square meters.

The structure is built with a hot-dip galvanized steel frame, ensuring long-term durability and resistance to corrosion. The wall system uses high-performance sandwich panels, with EPS, Rock Wool, or PU insulation options available to suit different climate and fire-resistance requirements. The house features an insulated steel roof system and a robust flooring structure consisting of fiber cement board with PVC or laminate finishes. Designed for long-term use, the unit offers a service life of 20–25 years or more, with a typical installation time of only 2–4 hours.

Floor Plan & Interior Layout Options

A standard 40FT expandable container house floor plan is configured as a 3-bedroom expandable home, including one to two bathrooms, an open-plan living and dining area, a designated kitchen space (optional fully equipped kitchen), and integrated storage cabinets.

To meet diverse project needs, the interior layout can be customized into alternative configurations such as a 2-bedroom mobile house, a luxury studio mobile house, or a granny flat with living space and bathroom, offering flexibility for residential, rental, or hospitality use.

Structure, Materials & Building Performance

The main structure adopts a heavy-duty galvanized steel frame, specifically engineered for long-distance transportation and repeated folding and unfolding. This makes the unit particularly suitable for relocatable housing projects and challenging environments, including coastal and high-humidity regions.

The wall and insulation system utilizes high-performance insulated panels, with optional Rock Wool insulation for enhanced fire resistance. The overall design is optimized for both cold winters and hot summers, ensuring stable indoor comfort. Windows are made from aluminum alloy frames, with double-glazed glass available as an upgrade, paired with Australian-style exterior doors that align with local market preferences.

Insulation & Climate Adaptability

Huisheng 40FT mobile house for winter and extreme climates is engineered to perform reliably across Australian desert regions, New Zealand’s cold and wet environments, and remote or coastal locations. The thermal and structural design ensures year-round comfort and energy efficiency.

Optional upgrades include thicker insulation panels, double glazing, thermal break window systems, and a solar-ready roof design, enabling the unit to meet higher energy-efficiency standards or off-grid living requirements.

Mobility Options & Foundation Solutions

The 40FT expandable container house supports multiple installation and mobility options to suit different project scenarios. It can be configured as a mobile house on a trailer, a mobile house with wheels, or installed on a fixed concrete foundation. Alternative foundation solutions such as steel piers or screw piles are also supported.

These options make the unit ideal for transportable granny flats, relocatable homes, and both temporary or permanent housing applications.

Installation & Deployment

The unit is delivered as a fully prefabricated mobile house, significantly reducing on-site construction work. No heavy civil construction is required, and 2–3 workers can complete the deployment within a short timeframe. Electrical and plumbing systems are designed with plug-and-play connections, enabling fast commissioning.

This makes the solution particularly suitable for fast housing deployment, emergency accommodation, and projects with tight construction schedules.

Customization & Smart Home Solutions

A wide range of customization options is available, including interior decoration packages, fully furnished solutions, and luxury interior finishes. Smart home features such as smart lighting systems and smart door locks can be integrated, along with solar power systems and off-grid water and power preparation.

The product supports OEM and ODM customization, making it suitable for distributors, developers, and project-based modular housing solutions.

Applications & Use Scenarios

The 40FT expandable modular house is widely applied as a granny flat in Australia and New Zealand, a backyard rental unit, a holiday cabin or Airbnb, worker accommodation, mining and remote camp housing, as well as site offices, medical units, and emergency or disaster relief housing.
