Why Choose a Garden Room in Wiltshire?
A garden room is one of the most efficient ways to add usable space to your home without the cost, disruption, or planning complexity of a traditional extension.
Our Wiltshire clients typically use their garden rooms and garden offices for:
Home offices
Garden studios
Home gyms
Treatment rooms
Multi-use family spaces
All of our cabins are built using fully insulated SIPs construction, meaning they perform like a proper room, not a seasonal structure.
Planning Permission in Wiltshire
One of the biggest advantages of a Backyard Cabin is that most builds fall under permitted development.
Our cabins are designed under 2.5m in height, meaning they typically do not require planning permission.
For homes in conservation areas or the North Wessex Downs AONB, we can provide guidance to ensure your garden room complies with local requirements.

Every Backyard Cabin is designed for comfort in every season.
Fully insulated walls, floor, and roof
