Why a garden room suits home working

A garden room gives you a proper commute — a short walk to the end of the lawn — and a clear boundary between work and home. There is no laundry pile staring at you, no dishwasher to empty, and no family traffic passing your desk. For video calls, the background is greenery rather than a hallway. But to use it every day, through a British winter and a muggy July, it needs to be built and serviced like a room, not a shed with a desk dropped inside.

Power and data: plan the backbone first

Electricity is the item most often underestimated. A single extension lead trailed across the grass will not do. Ask a qualified electrician to run a dedicated supply from the main consumer unit using armoured cable, buried at least 450mm deep with warning tape above it. A 16A or 20A supply is usually ample for a laptop, monitor, printer, router and a 1–2kW heater. If you want a kettle, a small fridge or power tools, consider 32A. Inside, fit more sockets than you think you need: at least four double sockets, plus USB-C charging points at desk height. Keep the lighting circuit separate so a fault on one does not plunge you into darkness. Electrical work in England and Wales must comply with Part P, so use a registered electrician and keep the certificate.

Data matters as much as power. Run at least two CAT6 Ethernet cables from the house to the garden room while the trench is open. One can feed a small network switch; the other can be a spare or feed a wireless access point. It is far cheaper to bury a spare cable now than to dig up a patio later.

Insulation and heating for year-round comfort

Insulation is what separates a usable office from a seasonal hut. Aim for a well-insulated floor, walls and roof, with a U-value around 0.18 W/m²K or better. In a timber frame, that often means 100mm of rigid PIR board in the walls and roof, and 100mm in the floor, with joints taped and gaps foamed. Avoid cold bridges at the corners and around the door. Double-glazed units with a low-e coating and warm edge spacers will reduce condensation and heat loss.

For heating, a 1–2kW electric panel heater or oil-filled radiator on a programmable thermostat is simple and effective. Infrared panels heat people and surfaces quickly, which suits intermittent use. If the budget stretches, a small air source heat pump can be more efficient, but it needs a well-insulated envelope to perform. Whatever you choose, keep a background temperature of 12–15°C when the room is empty to prevent damp and mould. Add trickle vents or a small mechanical ventilator to keep air moving; a sealed, insulated box will otherwise smell fusty by February.

Broadband that reaches the end of the garden

Wi-Fi rarely travels well through foil-backed insulation, thermal blocks and mature hedges. The reliable answer is a hardwired connection. A CAT6 cable from the main router to an access point or switch in the garden room will give you full-speed internet and a stable connection for video calls. If digging is impossible, a mesh Wi-Fi node placed in a window overlooking the garden can help, but it is a compromise. Powerline adapters sometimes work, though they may struggle if the garden room is on a separate electrical supply. A 4G or 5G router with an external antenna is a sensible backup for rural locations, and it can keep you working during a broadband outage.

Lighting, layout and daily comfort

Good lighting is not just about brightness. Use daylight as your main source, but position the desk perpendicular to the window rather than facing it, so you avoid screen glare and silhouette on video calls. Add a dimmable LED panel or pendant for general light, and a focused desk lamp for paperwork. A colour temperature around 4000K works well for concentration; warmer 3000K is kinder in the evening. Fit a blind or sheer curtain to control low winter sun and summer heat.

For layout, allow a desk at least 1.2m wide and 60cm deep, with space for a chair that supports your lower back. Include a lockable cupboard for files and a shelf for printer paper. If the room is small, use wall-mounted storage and a fold-down desk. Think about acoustics too: a rug, soft furnishings and acoustic panels reduce echo on calls.

Practical checks before you commit

In England, many garden rooms fall under permitted development, but rules differ across the UK. Typically, an outbuilding within 2m of a boundary can be up to 2.5m high; further away, up to 4m with a pitched roof. Check with your local planning authority, especially if you are in a conservation area or listed building. Building regulations may apply if the room is used for sleeping accommodation, but a home office is often exempt — electrical safety still matters.

Tell your home insurer about the new structure and its contents. Fit a lockable door and window, and consider an alarm or camera if the garden is accessible. Make sure gutters and drainage keep water away from the base. Finally, keep a simple maintenance routine: check seals, clear leaves, and air the room regularly. A well-planned garden room will repay you with quiet, focus and a commute that takes thirty seconds.
