From our Cheltenham base
Gloucester is close to our Cheltenham base, and we have built garden rooms for homes in and around the city. One of them is a cardio training room near Gloucester, built with a vaulted ceiling up to 3 metres so the owner could use an inclining treadmill.
Every room is made to order in the size and specification you need, whether that is a compact garden office, a gym with reinforced foundations or a room with a cloakroom or shower room. It is built on site by our team, and the average build takes around 8 days.
Every room below was designed for one customer’s garden and built on site by our team, including the cardio training room near Gloucester.

Planning permission is not normally needed for a garden room, but it depends on the size, position and use of the room. Under the national permitted development rules on the Planning Portal, a garden room is usually allowed without an application when:
Gloucester City Council has adopted 14 conservation areas across the city. The city itself is outside the Cotswolds National Landscape, which lies to the east. If your home is in a conservation area, outbuildings to the side of the house need planning permission. If your home is listed, permitted development does not apply in its grounds.
If you are unsure, check with Gloucester City Council before you order. You can also read our planning FAQs.
We talk through how you will use the room, your garden and your budget, then design a room to suit.
A 10% deposit secures your order, build slot and installation date.
A pad or screw foundation is prepared. The ground needs to be flat; we can carry out groundworks for an extra charge.
The average build takes around 8 days. Rooms are completed to regulations and ready to connect to the mains.

We also build garden rooms in the towns and villages around Gloucester.
Yes. Gloucester is close to our Cheltenham base, and we have built garden rooms in and around the city, including a garden cardio training room near Gloucester. See the project.
Usually not. Most garden rooms are permitted development, as long as they meet the national limits on height, position and size. Gloucester has 14 conservation areas, where outbuildings to the side of the house need permission, and different rules apply to listed buildings. Check with Gloucester City Council if your home is affected.
Build time varies with the size of the room and any extras, but on average a build takes around 8 days on site.
The cost varies significantly depending on the size, cladding, insulation and glazing you choose. Every room is made to order, so we quote for each project. Call 07977 102744 or request a free quote.
We take a 10% deposit to secure your order, build slot and installation date. A second payment of 30% is due before your installation date, and a third payment of 50% is typically due on the fourth day of installation. The final 10% is payable within 7 days of completion, once you are satisfied with your room.
Yes, but you would need to apply for planning permission, because it would be used as an additional bedroom rather than as additional living space.
Yes. We offer a 10-year guarantee on all roofs, and our windows are FENSA certified.
