Frequently asked questions
Everything buyers usually ask before ordering an expandable container house — cost, size, installation and living standards. Still unsure about something? Our engineers answer within one working day.
More QuestionsAn expandable container house is a prefab home that folds up to fit in shipping containers and unfolds on site to create more living area. It uses a steel frame, insulated wall panels and pre-fitted electrics and plumbing, making it a space-saving, fully built house ready from the factory.
The cost depends on size, configuration, insulation level and interior finishing. Taking a 20FT expandable container house as an example, the ex-factory price starts from US$6,000, excluding furniture and shipping cost.
A standard 20FT expandable container house is roughly 5.9 metres long when folded. Once unfolded, the usable space usually comes to about 35–40 square metres, depending on the layout you choose.
Most expandable container houses can be unfolded and structurally secured within a few hours. Total installation time depends on getting the foundation ready and hooking up basic services such as power and plumbing.
Yes. A correctly set-up expandable container house with good insulation and interior finishes can be used for permanent everyday living, with bedrooms, bathrooms and a full kitchen just like a small regular house.
Typical Use
How Our Houses Are Used
What each type of buyer tends to ask for, grouped by how the unit is used.
-
Residential
Most single-unit buyers are putting a house in a garden or on land beside an existing home, and they ask for the interior first — flooring, kitchen and bathroom in place — because they are moving in rather than building on. The 20FT suits this best: two bedrooms without taking over the plot.
Private homeownersGarden plots and family land -
Hospitality
Rental operators usually buy several units at once, and care less about floor area than about turnaround: independent access, a private bathroom, and an interior that still looks new after a season of guests. The 30FT is the common pick here, since it takes a corridor layout with two or three rooms.
Short-term rental operatorsMulti-unit sites -
Distribution
Distributors buy on repeatability: the same panel set, the same fittings and the same packing list on every order, so their install crews do not have to relearn the product. Packed volume matters as much as the unit itself, because freight is charged on the space taken inside the container.
