Custom Garden Rooms design and build garden rooms and self-contained living annexes across England, Wales and Scotland. Based in Telford and installing with their own in-house team, they work both bespoke and from pre-designed ranges, shaping each building around how it will be used — a home office, gym, studio, music room, sitting room, entertaining space or a residential annexe. Every building is fully insulated for year-round comfort, and completed examples can be seen at their Shropshire and Hertfordshire show sites — visitors who book a viewing receive £500 off with code VISIT26.

A tired garage in Shrewsbury has become a stylish, self-contained Custom Garden Rooms annexe, designed from the start as a short-term rental. With planning handled, a cleverly divided 7m x 3m layout and a private courtyard, it shows what a compact annexe can deliver.
