Garden Rooms in Westbury-on-Trym, Bristol.
Westbury-on-Trym and Henleaze are North Bristol at its most family-suburban — substantial 1930s and inter-war semis with wide, generous gardens. The brief is often more ambitious here: home gyms with garden bar zones, twin-volume garden offices, golf simulator rooms on the deeper plots toward Stoke Bishop.

Will I need planning permission in Westbury-on-Trym?
Most Arden & Oak garden rooms in Westbury-on-Trym fall within Permitted Development Rights — height kept below 2.5 m at the eaves, set back at least 2 m from boundaries, and under 50% of the original garden footprint.
