Garden rooms, offices & studios.
Built warm, built right.

Most garden rooms aren't really rooms, they're sheds with windows. Ours are properly engineered warm rooms you'll use year-round: insulated, glazed, wired, plumbed where needed, and finished to the same standard as the main house.

Why a garden room

Add a room without losing the house.

For a lot of Bristol families, the garden is the cheapest piece of buildable square metre on the property. A well-built garden office adds workspace without losing a bedroom. A studio gives a kid space. A gym keeps the spare room a spare room.

Done to permitted development limits, most don't need planning. Done properly, they're warm in February and cool in July, with their own electrics and, where it makes sense, a WC or shower.

What we build

Four kinds of garden room we deliver in Bristol.

Garden office

The most common brief, a quiet, properly heated workspace away from the house. Power, data, lighting plan and air-con or electric heating included.

Studio & creative space

Music room, art studio, photography space, sound treatment and lighting designed in from day one, not bolted on later.

Home gym

Reinforced floor, mirrors, ventilation, sound-deadened structure. Built to take a barbell and a year-round routine.

Multi-use rooms

Office plus guest room, studio plus shower room, gym plus pool changing area. We design split layouts so one outbuilding does several jobs.
