Product Description

Container modular house and prefab houses that can be used as a granny flat, spare room, rental investment, first home, downsizing, deluxe mining camp accommodation, crib room, training room, office and accommodation for caravan & holiday parks, bed and breakfasts and more!

When planning a compact dwelling for extended family or rental income, the 20ft Expandable 2 Bedroom Container Home Granny Flat delivers a practical layout that expands to roughly 5850mm by 6062mm. Inside, you get two separate bedrooms, a bathroom with shower and toilet, and a kitchen area. This makes it a versatile solution for a granny flat, guest suite, or even a small home office.

Built on a 3mm hot galvanized steel structure with 75mm EPS or rock wool sandwich panels for walls and roof, this 20ft Expandable 2 Bedroom Container Home Granny Flat is engineered for durability and insulation. The steel frame resists rust and corrosion, while the insulated panels help maintain comfortable indoor temperatures. The unit also includes double-glazed PVC windows and a steel or aluminum door with a secure lock, ensuring both comfort and security.

One of the standout advantages of this 20ft Expandable 2 Bedroom Container Home Granny Flat is its fast installation. The expandable design allows the house to be set up in as little as two hours, saving significant labor costs. It requires only a simple foundation of concrete blocks, and the entire unit is pre-wired with electrical distribution, lighting, and outlets. Optional accessories such as furniture, kitchen appliances, and air conditioning can be added to create a fully furnished living space.

For international buyers, the folding and expandable nature of this container home offers clear logistics benefits. When closed, the unit measures 5850mm by 2250mm by 2500mm, allowing two units to be loaded into a single 40HC container. This reduces shipping costs and makes the 20ft Expandable 2 Bedroom Container Home Granny Flat an economical choice for projects in remote or overseas locations. The manufacturer also provides free drawings and quick quotations to help you plan your project.

Whether you are looking to add a granny flat for aging parents, create a rental unit, or set up temporary accommodation for a mining camp or holiday park, this expandable container home offers a balance of affordability, durability, and comfort. Its hot galvanized steel construction and insulated panels are designed to withstand harsh weather, and the optional wall cladding adds an extra layer of protection and aesthetic appeal. Confirm specific customization options and local building requirements with the supplier to ensure the unit meets your project needs.
