A garden office is the same thing as a well-built garden room — put to the best use most of us have for one. If you work from home more days than not, the maths of a proper office at the bottom of the garden is hard to argue with: a permanent, insulated, year-round workspace for a fraction of the cost of an extension, without the kitchen table, the box room, or the commute. Below is what a garden office costs in the UK in 2026, the planning rules, and what separates a real office from a shed with a desk.
What does a garden office cost?
The UK market runs roughly £1,200–£2,500 per square metre for a professionally installed, year-round building, rising higher in London (our garden room cost guide has the full breakdown). A VeltHaven garden room specified for work starts at £32,950 fully installed (ATLAS Signature — including VAT, delivery, the triple-glazed sliding glass wall, fitted flooring and the concealed electrical first fix), with the level base and any extra electrical connection quoted from your site photos before you commit. The £26,950 Core package is the same building without the floor and electrics — a shell you finish yourself, which is why we don’t quote it as an office price.
For a dedicated office, the specification that matters is ATLAS (5×4m, 20 m²) — a single-use room done properly, with space for a full desk setup, shelving and a place to think. Step up to NOVA (5×5m, 25 m²) if you want a sofa, a second desk or space for clients.
The four things that make a garden office work
1. Year-round comfort, or it isn’t an office
An office you avoid from November to March is a summerhouse with a monitor in it. Genuine daily use needs real insulation (100mm PIR walls and roof, wall U-value ~0.23 W/m²K), proper glazing (our sliding glass wall is triple-glazed), and heating you can trust — a Daikin heat pump (included with the Executive package) heats in winter and cools in summer, which matters just as much in a glazed room in July. (Why most garden rooms fail this test.)
2. Power, light and connectivity
A working office needs sockets where the desk is, decent lighting, and reliable internet. The Signature package includes a complete concealed electrical first fix — a consumer unit installed, with wiring prepared for lighting, sockets and heating, run inside the walls while they’re built by a qualified UK-registered electrician to BS 7671; your electrician completes the second fix. Prefer it all done for you? Executive includes the full installation, tested and certified. For broadband, most customers run a wired connection alongside the electrical supply for a rock-solid link, or use a mesh Wi-Fi unit — at typical garden distances both work well; we’ll advise on your setup when we review your site photos. (Garden room electrics explains the dedicated circuit, Part P and typical costs.)
3. Separation: the underrated feature
The reason a garden office beats a spare bedroom isn’t square metres, it’s psychology: you leave for work and come home after it. Calls happen behind your own door. The laptop stops living on the kitchen table. For anyone who’s worked from home since 2020, that boundary is the feature you can’t retrofit into the house.
4. A planning position you don’t have to think about
Using a garden room as a home office is exactly the “incidental” use permitted development expects — most garden offices need no planning application when set back from boundaries and within height limits (2.5m within 2m of a boundary). Conservation areas and listed buildings differ, and an office is not sleeping accommodation — a room used as a bedroom or annexe changes the planning position, which is why we never market one that way. We assess your site as part of the design; see the planning guide.
Garden office FAQs
Can I use any VeltHaven garden room as a garden office?
Yes — office, gym, studio and snug are all the same building put to different uses. Choose the size for how you’ll work: ATLAS for a dedicated office, NOVA for office-plus-somewhere-to-sit, APEX if the room will do two jobs at once.
Do I need planning permission for a garden office?
Usually not — home-office use is incidental, and most builds sit within permitted development limits. Size, siting, conservation areas and prior extensions can change that, so check the planning guide or ask us to assess yours.
Can I put a garden office through my business?
That’s a question for your accountant, honestly — the answer depends on your business structure and how the building is used, and it has capital-allowances, VAT and capital-gains angles we’re not qualified to advise on. We’ll happily provide proper invoices and documentation for whatever route your accountant recommends. (More on the planning, insurance and tax basics: running a business from a garden office.)
Will video calls work from the bottom of the garden?
At typical garden distances, yes: a wired run alongside the electrical connection gives you the same connection quality as the house, and mesh Wi-Fi handles most gardens comfortably. If your building will sit unusually far from the house, tell us and we’ll flag the options when we review your photos.
How long does it take to get one?
Typically 4–8 weeks from order to installed building — a few days for photos and planning, 2–6 weeks manufacture, then installation, usually completed in around a day once your base is ready.
The bottom line
A garden office is the best-value permanent workspace most UK homeowners can add: from £32,950 fully installed (ATLAS Signature — the £26,950 Core package is the same building without the floor and electrics) for a room that works in January as well as June, with the planning position, electrics and warranty handled properly.
