Local questions

Westbury-on-Trym & Stoke Bishop — common questions

Is Westbury-on-Trym inside any Bristol Conservation Area?
No — Westbury-on-Trym and Stoke Bishop are outside all Bristol conservation areas. Most garden rooms here qualify for Permitted Development.
My Westbury-on-Trym detached house has a 20m garden — is that enough for a large studio?
Yes — 20m gives you a 5×5m studio (25m²) with comfortable access around the room. Most Westbury-on-Trym detached-house garden rooms are PD-sized and need no application.
Can we have an annexe for a dependent relative?
Yes — Westbury-on-Trym's wider plots support larger garden annexes (25m²+) with a bedroom, bathroom, and small kitchen. Most annexes need Building Regulations approval and may need a planning application. Tom will tell you what's needed on the site visit.
Can we have a pool house?
Yes — pool houses (changing room, small plant room, possibly sauna) are common on Westbury-on-Trym's larger plots. Most are 25–35m² and qualify for PD because of the wide rear gardens.
Are you VAT registered?
