Portable cabin solutions for sale
A portable cabin — often just called a portacabin — is a complete, insulated room built in a factory and delivered to your site ready to use. It needs only a firm, level base rather than full foundations, it moves when you move, and it is priced up front, before anything arrives.
Ours are built around a galvanised steel frame with insulated sandwich-panel walls, double-glazed PVC windows, LED lights and sockets. The same cabin works as an office, a canteen, a classroom or a spare room: only the layout inside changes. Pick the page that matches your job:
- Construction sites: site offices, canteens and drying rooms — see site cabins.
- Businesses, yards and depots: extra desks, a sales office or a meeting room — see portable office cabins.
- Schools and nurseries: portable classrooms and larger modular school buildings.
- Farms and estates: farm offices and seasonal farm workers accommodation.
- Living space: annexes and portable houses — anything with a bedroom normally needs planning permission and building regulations approval.
- Cabins that move between sites: steel cabins with a bolted frame, and how jackleg cabins compare with our crane-lifted cabins.
Portable cabin sizes, weights and prices
Every price below is ex works, + VAT, for a new cabin with door, double-glazed windows, lights and sockets. Delivery by crane lorry is quoted for your postcode in your written quote. Feet sizes are rounded so you can compare like for like with other suppliers.
Common widths are 2.3 m, 2.4 m and 3 m. Longer and wider cabins — footprints from 3 × 4 m to 3 × 12 m and from 4 × 4 m to 4 × 12 m — are built to order. The 2.4 × 6 m cabin has a 20ft footprint and fits standard transport.
Weight decides the size of lorry and crane, so we confirm the weight of your cabin in your written quote. As a guide, our small insulated panel cabins weigh from 100 kg (1.1 × 1.1 m) to 380 kg (2.6 × 2.6 m); full-size cabins weigh more.
| Portable cabin | Footprint | Floor area | Height | Price + VAT |
|---|---|---|---|---|
| Single room 13ft × 10ft | 3.00 × 4.00 m | 12 m² | 2.64 m | £3,290 |
| Site office 20ft × 8ft | 2.40 × 6.00 m | 14.4 m² | 2.64 m | £3,490 |
| Office 16ft × 10ft | 3.00 × 5.00 m | 15 m² | 2.64 m | £3,790 |
| Open-plan cabin 23ft × 10ft | 3.00 × 7.00 m | 21 m² | 2.64 m | £4,290 |
| Office with WC 23ft × 10ft | 3.00 × 7.00 m | 21 m² | 2.64 m | £4,890 |
| Two rooms and WC 23ft × 10ft | 3.00 × 7.00 m | 21 m² | 2.64 m | £5,190 |
Prefabricated and modular: how our portable cabins are built
Each cabin is made in the factory under ISO 9001:2015 quality management, so frames, panels and windows are built under cover — not pieced together in the rain on your site.
The frame is galvanised steel, bolted rather than welded. That is what lets a cabin be delivered flat-packed or assembled, combined with others into a larger modular building, and taken apart and re-used many times over its life. When it is finally retired, its materials are 100% recyclable.
Where fire performance matters — close to a boundary, or where people sleep — a rock-wool core is available in place of the standard EPS. We confirm the panel specification in your written quote.
| Part | Standard specification |
|---|---|
| Frame | Galvanised steel, bolted; metal parts in RAL 1019 |
| Walls | 50 mm EPS sandwich panels (PUR option), U-value 0.46 W/m²K |
| Roof | 125 mm EPS insulation, U-value 0.26 W/m²K |
| Floor | 2 mm PVC vinyl on 14 mm cement board, rated 200 kg/m² |
| Windows | PVC, double glazed, opening 90° |
| Finish | RAL 9002 electrostatic powder-coated steel |
| Snow load | 80 kg/m² |
Portable cabin designs and conversion ideas
Inside, a portable cabin is a blank box you divide the way the job needs. Our three standard 3 × 7 m layouts are open plan, an office with a WC at one end, and two rooms either side of a central WC. The drawing we send with your quote shows the door and window positions, so you can check the layout before anything is built.
- Open-plan office or meeting room: desks along the windows, a table in the middle.
- Office plus WC: plumbed on-surface, so it only needs connecting to water and drainage.
- Two rooms and a WC: a manager's office and a meeting room, or two bedrooms for staff — sleeping space normally needs planning permission and building regulations approval.
- Canteen or rest room: tables and a sink for a site or yard team.
- Changing and drying room: benches, hooks and a heater for wet gear.
- Showroom, studio or shop: full-height glazing or timber-effect cladding changes the look completely.
- Options confirmed in your written quote: heating or air conditioning, a kitchenette, extra doors and windows, internal partitions, cladding and colour.
Portable cabin installation and assembly
Assembled cabins arrive on a lorry with its own crane (HIAB). The driver lifts the cabin straight onto your base, so it is usually in place and ready quickly. You need clear access for the lorry and no overhead cables near the lift.
If the lorry can't get close, or you are ordering several cabins, they can come flat-packed and be assembled on site instead — see flat pack cabins.
- Quote: send an inquiry and we email a written quote and drawing.
- Base: prepare a firm, level base — a concrete slab or level concrete pads under the frame. We show you where the pads go on the drawing.
- Delivery day: the cabin is lifted onto the base, checked for level and handed over.
- Services: an electrician connects the supply; any cabin with a WC is connected to water and drainage.
- Planning: cabins used for building work on the same site are usually permitted development; cabins that stay for good often need permission. Check with your council — we can supply drawings for an application.
New or used portable cabins?
Used portable cabins for sale look cheaper, but the saving shrinks once you add haulage and craning — a used cabin needs both, just like a new one — plus repairs. Before you buy second-hand, check the floor for soft spots, the ceiling for water stains, the windows for misted seals and the electrics for a recent test certificate, and ask who pays for delivery.
A new cabin is built to your drawing, priced on this page and covered by a 12-month warranty against manufacturing and assembly faults.
Our products are used in over 140 countries. Production is ISO 9001:2015 and CE certified.
How they're built
Galvanised steel, sandwich panels, double glazing.
Every cabin starts with a bolted galvanised steel frame, 50 mm eps sandwich panel (pur option) walls and a 125 mm EPS roof, finished with PVC double-glazed windows.

Questions buyers ask us
How much does a portable cabin cost?
From £3,290 + VAT for a 3 × 4 m single room, £3,490 + VAT for a 2.4 × 6 m site office and £4,290 + VAT for a 3 × 7 m open-plan cabin. A 3 × 7 m cabin with a WC is £4,890 + VAT; delivery is quoted by postcode.
Is a portacabin the same as a portable cabin?
Yes. 'Portacabin' is the everyday name many people use for any portable cabin. Ours are insulated, steel-framed cabins factory-built and sold direct.
What sizes do portable cabins come in?
Priced sizes include 3 × 4 m, 2.4 × 6 m, 3 × 5 m and 3 × 7 m, all 2.64 m high. Other footprints from 3 × 4 m to 3 × 12 m and 4 × 4 m to 4 × 12 m are built to order.
Do I need planning permission for a portable cabin?
Not usually for a cabin used during building work on the same site, which counts as temporary permitted development. A cabin that stays for good, or is used for sleeping, normally needs permission — check with your council; we can supply drawings for an application.
How is a portable cabin delivered?
Assembled cabins come on a lorry with its own crane and are lifted straight onto your base, usually ready quickly. Flat-packed cabins are bolted together on site.
What base does a portable cabin need?
A firm, level base: a concrete slab or level concrete pads under the frame. It must be level so the doors and windows open freely.
Are portable cabins warm in winter?
Yes, with a heater. The walls reach a U-value of 0.46 W/m²K and the roof 0.26 W/m²K, so the heat stays in; we confirm heating options in your written quote. Try our winter warmth calculator.
Do you sell used portable cabins?
Our cabins are new, built to order and covered by a 12-month warranty. If you are comparing a used cabin, check the floor, roof, windows and electrics, and add haulage to its price.
