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!
A 20ft Expandable 2 Bedroom Container Home Granny Flat is a compact dwelling that ships folded and opens on site into a two-bedroom layout with a bathroom and kitchen area. The open footprint is roughly 5850mm by 6062mm, so the first check is whether that expanded size and the required clearance around it fit your plot, access route, and local setback rules. Because the unit arrives closed at 5850mm by 2250mm by 2500mm, confirm the delivery truck, crane, and site entry can handle both the folded and opened positions before you commit.
Construction centers on a 3mm hot galvanized steel frame with 75mm EPS or rock wool sandwich panels for walls and roof. That choice affects insulation, moisture behavior, and fire performance, so ask the supplier which panel is quoted and how it suits your climate. Double-glazed PVC windows and a steel or aluminum door with a secure lock are included, and the unit is pre-wired with a distribution box, lights, switches, and sockets. Optional kitchen, furniture, and air conditioning can be added, but confirm exactly what is included in the base price rather than assuming a turnkey package.
Installation is promoted as fast, with a simple concrete block foundation and setup measured in hours rather than days. Treat that as a site-dependent target: ground conditions, services, and local approvals can change the schedule. For a 2 bedroom container home, the practical questions are where the bathroom and kitchen drain, how power and water connect, and whether the floor structure and 6500kgs weight suit your prepared base. Ask for the assembly drawing and panel numbering so your team can plan the lift and connection work.
Shipping is a major cost driver. Two folded units fit one 40HC container, which lowers freight per home for overseas or remote projects. The manufacturer offers free drawings and quick quotations, and customization options such as color and wall cladding are listed. Before ordering a container granny flat, request the current specification sheet, confirm panel type and thickness, and check that electrical components match your local standards. Local building requirements, permits, and any certification needed for occupancy remain the buyer's responsibility to verify with the supplier and local authorities.
