Why OuterRoom

Built like part of your home, not a shed.

Fully insulated, all year

Insulated walls, floor and roof with high-performance glazing, plus heating and power, so it's warm in January and cool in July.

Year-round room

Designed bespoke around you

No off-the-shelf boxes. We design the size, layout, glazing and finish to suit your garden and exactly how you'll use the room.

Made to measure

Built to last, guaranteed

Quality materials and our own installation team, backed by a long guarantee and aftercare that doesn't end at handover.

20-year guarantee

Free electrical package

Lighting, sockets and power are included with every installation, fully certified, so your room is ready to use from day one.

Included as standard

No extension upheaval

You gain a full room without months of dust and disruption inside your house, and usually for far less than an extension.

Minimal disruption

Planning sorted for you

Most garden rooms fall under permitted development and need no planning permission. We check it and handle anything that's needed.

Usually no permission

How it works

Three steps from idea to finished room.

STEP 01

Free design consultation

We visit your garden or talk it through, understand how you want to use the space, and share ideas tailored to your home.

STEP 02

Bespoke design & fixed quote

You get a design drawn around you with the layout, glazing and finish, and a clear fixed price. The price you see is the price you pay.

STEP 03

Build & handover

Our own team builds your room with minimal disruption, finishes the electrics, and hands over a room that's ready to use, guaranteed.

Finance

From £24,750. Or spread the cost with flexible finance.

Adding a room to your home is a big step. Finance options let you spread it into manageable monthly payments, so you can get the room you want now. We'll talk you through it when we quote.
