Two-storey container houses double the floor area on a single foundation — suited to residential living, staff dormitories and compact site accommodation.
A quick-assembly two-storey container house stacks two standard modules on one foundation, doubling the usable floor area without needing more land. The upper floor is craned into place and bolted to the lower unit, with an internal or external staircase connecting them. It suits narrow plots, resorts and staff housing.
Two-storey container house that doubles the floor area on a single foundation, craned into place and bolted on site. Full-height glazing keeps the interior bright while solid panels on the other sides hold the heat in.
One standard module: double bed at one end, kitchenette run along the wall, and a separate en-suite with corner shower, basin and WC — the base unit behind every container house. In a two-storey build this plan is used per level, so the same module serves as the ground floor and again above.
A two-storey unit is two of our standard detachable modules stacked - 5950 x 3000 x 2800 mm each - giving roughly 32 m2 of floor area across both levels.
8 Houses Per 40HQ
Each level ships as the same flat pack, so a 40HQ still holds 17 modules: eight complete two-storey houses plus one spare module. A 20GP holds 7 modules, or three houses.
4 Workers, 3 Hours Per Level
Each level closes in about three hours with four workers; the upper module is then craned on and bolted through the corner castings, the only step that needs lifting gear.
Open Between Floors
Floors can be opened for a connecting stair, fitted with glazing, or partitioned into separate rooms - the two levels do not have to be identical.
Built for Stacking
3.5 mm galvanised corner pieces and ISO corner castings carry the load between levels: 200 kg/m2 floor load, Class A fire resistance, magnitude 8.0 seismic and Grade 13 wind resistance.
15-20 Year Service Life
15 to 20 years with normal maintenance on a bolted panel system, where individual rockwool panels and glazing can be replaced without touching the frame.
Shipping Efficiency
8 Houses Per 40HQ
A quick-assembly two-storey house is two of our standard 5950 x 3000 x 2800 mm modules stacked, so it ships as the same flat pack. A 40HQ still carries 17 modules - that is eight complete two-storey houses plus a spare module, or 17 single-storey ones if the site would rather build out than up. Each level closes in about three hours with four workers; the upper module is then craned on and bolted through the corner castings, which is the only step that needs lifting gear.
In a quick-assembly build the two levels can be opened into one space with a connecting stair, fitted with glazing, or partitioned into entirely separate rooms — the building does not have to be identical floor to floor.
That flexibility suits the same unit to a family home, a two-unit rental, or an office below with accommodation above.
A quick-assembly two-storey unit gives two full levels of living space while taking up the footprint of a single garden room, which matters where the plot is narrow or the setback rules are tight.
The levels can be linked internally or given separate entrances, so the building serves either as one home or as two independent units.
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.
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.
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.
Crane Lifting Installation
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.

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.
Prefab distributorsRepeat and project orders
What a Prefab Container House Is
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.
Frequently Asked Questions
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.
