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!
An expandable prefabricated house is engineered to fold flat for transport and then expand on site, creating a full-size living area. The 20ft model opens to 5850mm by 6062mm, while the 40ft version reaches 11860mm by 6062mm, offering flexible layouts for bedrooms, kitchen, and bathroom. The hot-dipped galvanized steel frame and 75mm sandwich panel walls provide structural strength and thermal insulation, making the unit suitable for year-round use in various climates.
For buyers planning a granny house, the expandable design allows installation in a backyard or existing property in as little as two hours, requiring only a simple concrete block foundation. This reduces labor costs and minimizes disruption to the surrounding area. The pre-installed bathroom and kitchen options mean the space is immediately functional, offering independence for elderly family members or guests. The 30-40 year service life of the galvanized steel frame ensures long-term value.
As a tiny house, this expandable prefabricated house maximizes space efficiency without sacrificing comfort. The 75mm EPS or rock wool sandwich panel walls provide thermal insulation, while the double-glazed windows and sealed doors help maintain a stable indoor environment. The unit is also designed to be wind-resistant and anti-seismic, adding a layer of safety for occupants. Buyers can choose from standard colors or request customization to match their aesthetic preferences.
When sourcing an expandable prefabricated house, it is important to confirm the specific dimensions, material specifications, and included accessories with the supplier. The product description lists options such as 20ft and 40ft models, with variations in the number of bedrooms and kitchen layouts. Buyers should also verify the electrical standards and any additional features like air conditioning or furniture packages. This ensures the final unit meets the intended use, whether as a permanent residence, a rental unit, or a temporary accommodation.
