Two bedrooms at the rear, with an L-shaped living area, a four-seat dining table and a kitchen run along the wall. The bathroom sits between the living space and the master bedroom.

Folded to 9000 x 2200 x 2480 mm, the 30FT carries a 54 m² floor plan as a single road-legal unit — one width on the road, three or four rooms once open.
The complete 30FT ships folded inside a single 40HQ container, factory-finished. No crate of loose panels, no parts list to reassemble on site.
Five workers have it weathertight within 2 to 3 hours of opening the container — roof expanded, walls lifted, unit closed.
The extra length allows one to four bedrooms off the same shell, with one or two bathrooms, plus living room and kitchen — the layout is set by the order, not by the box.
Galvanised square-tube frame rated for 200 kg/m² floor load, Class A fire resistance, magnitude 8.0 seismic and Grade 13 wind resistance.
A 20-year service life on a galvanised frame with EPS sandwich panels — which is what makes it usable as long-term accommodation rather than a stopgap.
Shipping Efficiency
The 30FT folds to 9000 x 2200 x 2480 mm and ships as one complete unit in a 40HQ container. There is no crate of loose panels and no parts list to reassemble on site — the container is opened and the building comes out.
Because the whole 54 m² unit travels in one piece, delivery is predictable: one container, one building, one handover. For phased projects where units arrive across several shipments, that makes scheduling far easier.
Interior
The 30FT gives 54 m² that can be planned as anything from a one-bedroom unit to a four-bedroom one, with one or two bathrooms, a living room and a kitchen.
Because the internal partitions are set at the factory, the layout on site matches the drawing — there is no cutting or refitting once the unit is open.
Applications
The 30FT gives 54 m², which is a genuine two-bedroom home rather than a converted shed — enough for a couple, a small family, or a rental that has to feel permanent.
Placed behind the main house it becomes a self-contained unit with its own entrance, kitchen and bathroom, sharing nothing with the main building except the utility connection.

HUIYANG
HUIYANG follows internationally recognized manufacturing standards, with ISO 9001 certification and complete internal quality control processes. We use standardized production and professional team training to make sure every expandable container house is built stably and accurately. Our CE and other company certificates show we take safety, reliability, and international standards seriously.
HUIYANG
HUIYANG provides a simple, efficient ordering process specially designed for compact expandable units and multi-unit projects.
Tell us how the expandable container house will be used, how many units are needed, and where they will be delivered.
Select the preferred interior layout and functional setup based on living, working, or temporary accommodation requirements.
Once we confirm all the details, we start production in our factory using standard procedures. This makes sure every expandable unit is built with consistent quality.
Completed houses are folded, protected, and loaded efficiently, allowing up to four expandable units to fit into one 40FT container.
We help arrange shipping and offer instructions to make sure each expandable expandable unit can be easily unfolded and set up on site.

The expandable container house arrives folded. It is lifted by crane onto a prepared base, then unfolded and fixed into place. Final sealing, trims and utility hook-ups complete the on-site installation — typically within 2 to 3 hours with a small crew.
Each unit ships with ISO corner blocks and lifting points marked at the factory, so a standard crane can set it down onto prepared foundations or footings in a single controlled lift. No site welding and no temporary scaffolding are needed for placement.

The unit is delivered folded inside a 40HQ container and set down on a level base. Both sides are unfolded and locked with support legs, then sealing strips and trims go on, followed by the electrical and plumbing connections. The interior is finished at the factory, so nothing has to be built on site.

Every unit ships with an installation manual and a step-by-step video covering the fold-out sequence, sealing and utility connections. Our technical team stays reachable by email and phone throughout the installation and can walk your crew through any step on a video call.
Spare parts — sealing strips, window and door hardware, electrical fittings — stay available after delivery, so a damaged component does not mean replacing a panel. Distributors and project customers also get layout drawings and support through the first unit on site.
Typical Use
What each type of buyer tends to ask for, grouped by how the unit is used.
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.
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.
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.
A prefab container house is built on a galvanised steel frame and finished in a factory before it ships. Depending on the type it either travels flat-packed as panels, unfolds from container width on site, or stacks as two storeys — but in every case walls, insulation, wiring and fittings are complete before the container is opened.
The range runs from a single 16 m² module or a self-contained bathroom unit, up to a 72 m² expandable house with four bedrooms and three bathrooms. Footprints and room counts vary by model, and the sections above give the figures for this one.
Because there is no second fit-out stage on site, only sealing, trims and the utility connection remain after delivery. That is what keeps installation to hours rather than weeks, and what makes these units practical for remote sites and staged projects.
A prefab container house is built on a galvanised steel frame and finished in a factory before it ships. It travels either flat-packed as panels or folded to container width, then becomes a finished room or house on site. Walls, insulation, wiring and fittings are all complete before the container is opened.
From a single self-contained bathroom unit up to a four-bedroom house with three bathrooms. Standard layouts pair bedrooms with a kitchen, a bathroom and a living area. The exact count depends on the footprint, and the sections above list what this model takes.
A detachable container module closes in about 3 hours with four workers — no welding, crane or forklift needed. An expandable unit unfolds and is fixed in place in 2 to 3 hours with a small crew and a crane or forklift. A two-storey house is two modules, so allow about 3 hours per level plus the lift of the upper module. Knock-down bathroom units take about an hour with two people.
Detachable container modules flat-pack 17 to a 40HQ or 7 to a 20GP — that is 8 complete two-storey houses per 40HQ. Expandable units ship 1 to 2 per 40HQ depending on size, and quick-assemble toilets ship 65 single cubicles knock-down or 18 fully assembled per 40HQ.
Residential living, staff and worker accommodation, site offices, rental cabins, guest houses, temporary housing and sanitation for camps and events. The same structure serves all of them; only the internal layout and fit-out change.
Partitions are set at the factory, so the layout is agreed before production rather than changed on site. Tell us the bedroom and bathroom count you need and we will confirm which footprint takes it. Within the same frame, finishes, bench positions and window placement can be adjusted.
ISO 9001 for quality management (GB/T19001-2016), CE marking under the Construction Products Regulation with EN 1090 steelwork verification, and RoHS compliance for restricted substances. Certificates and test reports are available on request.
Every order includes a written installation manual and a video covering the assembly or fold-out sequence, sealing and utility connections. Our technical team stays reachable by email or phone during installation, and spare parts - sealing strips, window and door hardware, electrical fittings - remain available after delivery.
