Garden Office Buying Guide
How To Specify A Garden Office That Works All Year
Sizing your office around how you actually work
A single-desk office with storage works comfortably from 3m x 2.5m. Add a second desk, a meeting chair or a client-facing area and 4m x 3m is a better starting point. If you plan to hold meetings or run a small team, look at 5m x 3.5m upwards so the space does not feel cramped once furniture is in.
Think about the layout before the size. Where the desk sits relative to the doors determines glare on your screen, whether you are on camera with your back to a window, and how much usable wall you have left for shelving.
- 3m x 2.5m — single desk, chair and storage unit
- 4m x 3m — desk, seating area and filing or shelving wall
- 5m x 3.5m — two workstations plus a meeting table
Broadband, power and connectivity
Reliable connectivity is what separates a usable office from an expensive shed. In most gardens a good mesh Wi-Fi node handles it, but for a building further from the house, or where the walls are heavily insulated, a hardwired ethernet run is the reliable option. We can run data cable alongside the armoured power cable during installation — far easier than retrofitting later.
Our electrical package includes armoured cable from the house consumer unit, its own protected circuit, double sockets, fire-rated LED downlights and a thermostatic heater. Tell us where your desk will sit and we position sockets accordingly.
Acoustics, light and video calls
Insulation does double duty: it keeps heat in and outside noise out. Traffic, neighbours and garden noise drop away noticeably once you close the door, which matters if you are on calls all day.
For light, north-facing glazing gives soft, even daylight with minimal screen glare. South-facing glazing is brighter but benefits from blinds and, in some builds, an air conditioning unit to control summer heat gain.
Tax, business use and resale
Many clients ask about claiming the cost through their business. Rules vary depending on your structure and whether the building is used exclusively for work, and there can be capital gains implications on sale — always take advice from your accountant before deciding how to buy.
On resale, a properly built, insulated and electrically connected garden office is a genuine selling point. Estate agents routinely list them as additional usable space rather than as a garden building.
Garden Office FAQs
Practical answers for anyone planning to work from the bottom of the garden.
Do I need planning permission for a garden office?
Usually not. A garden office normally falls within permitted development if it is single storey, no more than 2.5m high within 2m of a boundary, not forward of the principal elevation, and used incidentally to the dwelling. Conservation areas, listed properties and some estate covenants change this, so we check before quoting.
Will I get decent Wi-Fi in the garden office?
In most gardens a mesh node or Wi-Fi extender is enough. For guaranteed speed we recommend running an ethernet cable at the same time as the power cable during installation — it is inexpensive at build stage and gives you a fully reliable connection.
How much does a garden office cost?
Prices depend on size, cladding and glazing, but every LouMil quote is a fixed all-inclusive price covering insulation, electrics, heating, doors, windows and installation. Our online calculator gives an instant figure for your chosen specification.
Can I use it in winter?
Yes. Floor, wall and roof insulation, double-glazed doors and windows and a thermostatic heater mean the office is comfortable through winter. Most clients leave the heater on a low frost setting overnight so it is warm first thing.
Is a garden office cheaper than an extension?
Typically yes, and considerably faster. There are no building regulations sign-offs for a standard incidental-use garden office, no scaffolding, and no months of disruption inside your home. Most installations are complete within 3-5 days.
Do you install garden offices nationwide?
Yes. We design, build and install nationwide across the UK using our own installation team, so the same people who build your office are the ones who fit it.
