From our Swindon base
We build garden rooms for homes in Newbury and West Berkshire from our Swindon base. Many of our customers want a garden office to work from home, a gym, or a room for music, films or the family.
Every room is made to order in the size and specification you need, with options such as air conditioning, a cloakroom or shower room, and high-speed data cabling. It is built on site by our own team, and the average build takes around 8 days.

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:
The North Wessex Downs National Landscape covers around 74% of West Berkshire and encircles Newbury. If your home is in the National Landscape or a conservation area, outbuildings to the side of the house need planning permission, and in the National Landscape the total area of outbuildings more than 20 metres from the house is limited to 10 square metres. If your home is listed, permitted development does not apply in its grounds.
If you are unsure, check with West Berkshire 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.

Usually not. Most garden rooms are permitted development, as long as they meet the national limits on height, position and size. Different rules apply on designated land such as the National Landscape and conservation areas, and in the grounds of listed buildings, so check with West Berkshire 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.
