Container Garden Office & Room

A proper room at the end of the garden: warm, quiet, yours.

The commute that takes ten seconds

Working from the kitchen table was never the plan. A garden room gives you the thing a spare bedroom can’t: a door you close, a space that’s only for work, and a clean line between the job and the rest of the house. You walk down the garden, you’re at work; you walk back up, you’re home. No spare-room compromise, no folding the office away every evening.

We build garden offices that feel like rooms, not sheds. The steel container is the bones (weatherproof, secure and strong) and inside it we build a warm, quiet, finished space with proper insulation, real glazing and a finish you’d be happy to take a video call in front of. It’s the kind of room that adds a usable space to your home without the cost, mess and months of an extension, and without losing a chunk of the house to it.

Warm in winter, cool in summer, genuinely

A garden room lives or dies on insulation, and this is where corners get cut elsewhere. We insulate walls, floor and ceiling to a standard that holds heat through a Manchester winter and keeps the room comfortable in summer, then seal it properly against draughts. Add heating or air conditioning and it’s a room you’ll use every day of the year, not just when the weather’s kind. Big glazing, whether a picture window, sliding doors or bi-folds, brings in light and a view of the garden while the insulation behind it does the quiet work of keeping you comfortable.

Finished like the inside of a home

Jack’s background is kitchen fitting: fifteen-plus years of precision joinery in tight, finish-critical spaces. That’s exactly the craft a good garden room needs. Square reveals around the glazing, neat skirting and trims, a lined finish that takes paint cleanly, and built-in joinery: a desk that fits the wall, shelving that lines up, storage that uses every inch. The room is designed around how you’ll actually use it, then finished so it looks like part of the house rather than a unit dropped in the garden.

Because we keep our own container stock, your build starts when it’s agreed rather than when a supplier gets round to us, which keeps lead times short.

Planning: usually permitted, always worth checking

For most people a garden office or room counts as a permitted development outbuilding, so no planning application is needed, provided it’s behind the house, single storey, kept low near boundaries and doesn’t cover more than half the garden. Stricter rules apply in conservation areas, AONBs and to listed properties.

One firm rule: the moment a garden room is used for sleeping, whether a guest annexe or an Airbnb let, it needs full planning permission and must meet Building Regulations. Day-use offices and rooms generally sit under those thresholds, and Building Regs typically don’t apply to a detached building under 15m² internal with no sleeping use. Electrics are the exception: Part P always applies, and we wire to it. We’ll talk you through where your build sits, and we always recommend confirming with your local planning authority and considering a Lawful Development Certificate for peace of mind. (Always verify with your local planning authority. Scotland, Wales and Northern Ireland differ from the England guidance above.)

Delivered, sited, ready

The room is built at our workshop and arrives finished. For most gardens it sits on levelled pad stones, with no foundations to dig or concrete to pour, and is craned into position by HIAB lorry over fences and walls, levelled, and left ready. In most cases that’s a single day from lorry to working desk. If access is awkward, we plan it with you well ahead.

And if you move, it comes with you. A garden room you’ve fitted out to your taste isn’t something you have to leave behind.

A room that earns its place

Whether it’s a home office, a studio, a quiet reading room or a space for the kids to spread out, a container garden room gives you genuinely usable square footage for far less than an extension and with none of the upheaval. It’s backed by our 5-year structural guarantee on the shell. Tell us how you’ll use the room and we’ll design, build, deliver and site it, ready to walk into.

Garden Office & Room: common questions

Do I need planning permission for a container conversion?

For a day-use garden building, such as a gym, office, room, bar or studio, you usually fall under permitted development and need no application, provided it sits behind the house, is single storey, is kept low within 2m of a boundary (max 2.5m high there), covers no more than half your garden and has no veranda or raised platform. Conservation areas, AONBs and listed properties have tighter rules. Anything used for sleeping or letting always needs full planning permission. Always verify with your local planning authority. Scotland, Wales and Northern Ireland differ from this England guidance, and a Lawful Development Certificate is worth considering for peace of mind.

What about sleeping in it, or using it as an Airbnb or annexe?

Any space used for sleeping or letting, such as a guest annexe, a holiday let or an Airbnb, always needs full planning permission and must meet Building Regulations, without exception. That covers insulation, ventilation, fire safety and how services are installed. We build glamping and holiday-let units to that sleeping specification from the start and will guide you through the planning route, but the permission itself is granted by your local authority.

Do Building Regulations apply?

For a detached garden building under 15m² of internal floor area with no sleeping use, Building Regulations generally do not apply. Between 15m² and 30m² there are conditions, mainly around proximity to boundaries and fire. Any sleeping accommodation brings full Building Regs into play. One thing always applies regardless of size: Part P, covering electrical work, and we wire every build to it. Always confirm your specific case with your local authority building control.

What foundations does it need, and how is it sited?

For most gardens, none in the traditional sense. A container is structural in its own right, so we typically site it on levelled concrete pad stones or a simple prepared base, with no digging foundations and no waiting for concrete to cure. On softer or sloping ground we will advise on the right base. The unit is craned into final position, levelled and left ready.

How is it delivered, and how much access do you need?

The finished unit is delivered on a HIAB lorry, a lorry with a crane that lifts the container over fences, walls and hedges into position, so the lorry itself does not need to reach the exact spot. We do need clear access for the lorry to get close enough and overhead room for the crane. Tight or unusual access is usually workable, but we assess it with you before delivery day so there are no surprises. We deliver nationwide from our Radcliffe base.

Is it insulated enough to use all year round?

Yes. Proper insulation is the difference between a usable room and a cold steel box, and it is where cheaper conversions cut corners. We insulate walls, floor and ceiling to a real standard and seal against draughts, so the space holds heat through a Manchester winter and stays comfortable in summer. Add heating or air conditioning and it is a genuine every-day-of-the-year room.
