Cube Garden Rooms is based in Cheltenham and Swindon, and Cheltenham is where much of our work happens. Seven of the nine projects in our portfolio were built in Cheltenham and Charlton Kings, from a sunken garden gym to a guest house with its own shower room.
Every room is made to order in the size and specification you need, so it can fit a narrow town garden or a larger plot on the edge of the hills. We design it around your garden and the way you want to use it, then build it on site. The average build takes around 8 days.
Each of these rooms was designed for one customer’s garden in Cheltenham or Charlton Kings and built on site by our team.
Gym
A garden gym sunk into the ground for a high ceiling, with air conditioning, mirrored walls and bi-folding doors.
Gym and office
A gym, home office and composite decking area designed for a confined space, with reinforced foundations and a slatted partition wall.
Office and snug
A shared office and snug with a separate office space, large cedar beams and an outdoor decking area.
Guest house
A guest house with a toilet and shower, storage area and utility room, plus integral blinds and internal sliding doors.
Music and cinema
A music room and home cinema with surround sound, ceiling speakers and Cat 6 high-speed data cabling.
Studio
An art studio with adjustable track lighting, designed around the client’s specific requirements after a site visit.
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:
Cheltenham sits at the foot of the Cotswold escarpment. Beyond Leckhampton, Charlton Kings and Prestbury the land rises into the Cotswolds National Landscape, and parts of the town are conservation areas. On this designated land, 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 Cheltenham Borough 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.

“They worked with us to create a bespoke room that gives us the extra space we needed for an office and snug. The service was excellent, the team were friendly, punctual, very tidy and worked very hard to get the job done quickly.”

Yes. Cheltenham is one of our two main bases. We have built garden gyms, garden offices, a guest house, a music room, an art studio and a storage room for customers in Cheltenham and Charlton Kings. See our projects.
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 Cheltenham Borough 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.
