About Keynsham & the villages between

What garden rooms typically look like in Keynsham & the villages between

Keynsham is outside the Bath and Bristol conservation areas, so most garden rooms qualify for Permitted Development.

Every property is different, so Tom will always confirm what's actually there on the site visit before quoting.

Local questions

Keynsham & the villages between — common questions

Is Keynsham inside any Conservation Area?
No — Keynsham is outside the Bath and Bristol conservation areas. Most Keynsham garden rooms qualify for Permitted Development.
My Keynsham 1930s semi has a 15m garden — is that enough for a big studio?
Yes — 15m gives you a 5×4m studio (20m²) with comfortable access around the room. Most Keynsham 1930s semi garden rooms are PD-sized and need no application.
Can we have an annexe for a dependent relative?
Yes — Keynsham's wider plots support larger garden annexes (25m²+) with a bedroom and small bathroom. Most annexes need Building Regulations approval and may need a planning application. Tom will tell you what's needed on the site visit.
What about the villages between Keynsham and Bath/Bristol?
