Garden rooms
Your garden room. Built to last.
A garden room that's as strong as steel, warm all year and delivered ready to use. We convert a new or one-trip shipping container into a fully insulated, finished room for working, relaxing or entertaining. It's built at our Thirsk workshop and craned into your garden. Prices start from £12,000.
- Insulated for year-round use as standard
- Designed & built in Thirsk, North Yorkshire
- Delivered across the UK
What's included as standard
- Spray foam insulation for year-round use, with no cold spots and no condensation drips
- Internal cladding and LVT flooring
- Bifold or French doors to open up to the garden
- Spotlights, sockets and a full electrical installation
- AC and heating, so it's comfortable in July and January
Ways people use their garden room
- Garden office: a proper workspace with a two-minute commute that keeps work out of the house. See our Home Office model.
- Entertaining space: media wall, bar area, home cinema or games room. See our Garden Room model.
- Studio or treatment room: for therapists, tutors, artists and musicians.
- Home gym or wellness room: see container gyms and sauna and recovery rooms.
Sizes and prices
Most garden rooms are built from a 10ft, 20ft or 40ft container. A 20ft unit gives about 14 square metres inside, enough for a desk and a sofa, or a bar and seating. Prices depend on the size, doors, glazing and finish you choose. The configurator shows you a live price as you build.
- 10ft: from £12,000
- 20ft: from £14,000
- 40ft: from £18,000
Container or timber garden room?
A timber room is built on site over several days or weeks. A container room arrives finished in a single day, is far harder to break into, and won't rot, warp or need re-treating. If you move house, it can come with you.
Planning permission
Many garden rooms in England are allowed under permitted development, as long as they're single storey, behind the front of the house, and don't cover more than half the garden. The tricky one is height: if the room is within 2 metres of a boundary, it must be no more than 2.5 metres high. A standard container is about 2.6 metres tall, so we'll advise on siting and the base to keep you within the rules, or help with an application where you need one. Read our planning guide, and always check with your council.
Delivery and installation
Your room arrives fully finished on a crane lorry. You'll need a level base (concrete pads, a slab or ground screws) and access for the lorry to get near the spot. Our team checks access and the base at the survey stage, then connects the electrics once it's in place.

Most garden rooms take 4–6 weeks to build in our Thirsk workshop, and are installed in a single day.
Can I have a toilet or shower?
Yes. A washroom can be added in set positions. Use the configurator to see the options.
Do you deliver outside Yorkshire?
Yes, we deliver across the UK. See our Yorkshire work.
