20FT Dual Wing Expandable Container House: 37 m² on One Truck

A dual wing expandable container house travels 2.2 m wide and opens to 6.3 m. That is 37.2 m² of floor from one 20ft footprint, and two units ride a single 40HQ. Inside, the space takes two bedrooms and a bathroom. Or one open room for a site office, a clinic or a glamping cabin. The bathroom, the wiring, the windows and the door are already in when it leaves us. Your crew lands it on four pads and opens both wings. Four people, one morning, no site welding.

Customise It From the Cladding In

Most buyers change the outside first. We cut the wall panels to any RAL colour, and the skin can be flat steel, wood grain or corrugated. Windows and doors are cut where you want them, not where the panel happens to end. Inside, the partitions move with your floor plan. If the kitchen runs along the far wall, the sockets and the drain go there. We draw it once and keep the drawing, so a repeat order matches the first batch.

What you can change
· Cladding in flat steel, wood grain or corrugated, any RAL colour
· Window count and size, sliding or fixed, single or double glazed
· Door position and swing, steel security or glass
· Partition walls, so two bedrooms become one open room
· Socket, switch and drain positions, set from your plan
· Kitchen run and air conditioning, fitted at the plant

Whole-House Waterproofing, Tested Before It Ships

Water gets into a folding house at the joints, not through the panel. So the joints are where we spend the money. Each hinge line carries an EPDM seal that compresses when the wing locks. Roof seams lap in the direction the rain runs, with a flashing plate on top. Floor drains are sealed and set before the deck goes down. Then we put a hose on the finished unit in the plant, at storm pressure, and check the inside for damp.

Where the water stops
· EPDM seal along every hinge line, compressed by the cam locks
· Roof seams lapped one way, with a flashing plate on top
· Floor drains sealed and set before the deck goes down
· Panel joints taped and sealed in the plant, not on site
· Door sill raised, so standing water runs away from the frame

Frame and Panels: What Holds It Up

The frame is Q235B steel. Main beams run 2.5 mm, and every frame is welded on a jig, then hot-dip galvanized as one piece. That order matters. Weld a galvanized tube and the zinc burns off at the joint, which is exactly where water sits. Walls are 65 mm EPS as standard, with a rock wool core when your code asks for a Class A wall. With the wings locked, the unit takes 120 km/h of wind, and the anchor detail is written for seismic level 8.

The numbers that matter
· Main beam 2.5 mm, wing frame 40×80×1.5 mm, all hot-dip galvanized
· Zinc inside and outside every tube, not only the face you see
· 65 mm EPS wall, 50 mm EPS roof, rock wool for a Class A wall
· 120 km/h wind with the wings locked
· Seismic level 8 design, anchor layout issued per site
· Frame service life 30 years

A Morning to Open, Not a Season to Build

A 20ft expandable container house arrives folded, with the braces bolted on. Landing it on the pads takes about half an hour. Both wings run out and lock in around ninety minutes with a torque wrench. Water and power take another hour. Four people are finished in a morning, and none of it is wet work, so the floor is dry the same day. We send the pad drawing with the order, so the ground is level before the crane arrives.

Already fitted when it lands
· Bathroom with pan, basin, shower and sealed drain
· Wiring, distribution box, sockets and lights
· Windows, entry door and locks
· Floor and ceiling finishes
· Kitchen run and air conditioning, if ordered

Warranty, Paperwork and the Questions Buyers Ask

The unit carries a two-year warranty, and it covers the frame and panel delamination. Every crate ships with test reports for the wiring and the panel fire rating. CE documents come with it when your customs broker asks. The two questions we hear most are about seals and panels: can either be changed on site? Yes, both. The seal pushes into a groove, and the panel unbolts from the frame with the wing closed.

What is in the crate
· Warranty sheet with the frame and panel terms
· Test reports for wiring and panel fire rating
· CE documentation for customs
· Packing list that matches the crate, item for item
· Assembly video in your language

Shipping: Two Units in a 40HQ, and It Folds Back

Folded, the unit is 2.2 m wide and 3,200 kg. Two fit a 40HQ, and the third slot carries spares and panels. Freight is where an expandable unit earns its price back, and folding is the reason. Moving on site works like delivery in reverse. Close the wings, bolt the braces, lift on the four heads and travel folded. We rate it for about fifteen close, move and reopen cycles. A standard flatbed takes it without a permit in most markets.

How it travels
· 2.2 m folded, 3,200 kg, two units per 40HQ
· Four lifting heads welded into the posts, so no sling wraps the wall
· Braces bolt into the same holes every time
· Braces and slings travel inside the unit
· Loading photographs sent with the documents

One Frame, Many Uses: Office, Cabin, Clinic, Dorm

Most buyers take the same unit for one of six jobs. A site office, with a counter and a filing wall. A gatehouse, set so the window looks down the road. A dormitory, with four bunks and a shower at the end. A glamping cabin, with a deck bolted to the door side. A canteen or clinic, where the layout follows the equipment inside. Or a small shop, counter at the front and stock behind. The frame, the panels and the folding wings are identical in all six. What changes is the plan, the fittings and the colour. That is why a spare wall panel fits every unit we ship. A repeat order matches the batch before it. Send us the use and the site plan, and we will draw the layout around it.
