About Larkhall

What garden rooms typically look like in Larkhall

Larkhall gardens are mixed — the Victorian and Edwardian terraces have 8–12m of usable rear garden depth, while the 1930s semis on the northern edges have 12–18m. Most Larkhall properties are outside the Bath Conservation Area (which runs through central Bath).

Honest note: The descriptions below are generalisations — what's typical or commonly found in Larkhall, based on the area's documented housing stock and garden sizes. Every property is different, so Tom will always confirm what's actually there on the site visit before quoting.

Planning & permissions

The planning context in Larkhall

Most Larkhall garden rooms qualify for Permitted Development because the properties are outside the Bath Conservation Area. Tom will tell you on the site visit whether PD applies for your specific property.

Common garden-room patterns in Larkhall

Common Larkhall garden room patterns: 4×3m garden offices (12m²) sized for the typical rear gardens, 5×3m studios (15m²) on the wider semis, occasional cedar-clad garden gyms, and occasional garden annexes on the larger Victorian semis. Most jobs qualify for PD.

Local questions

Larkhall — common questions

Is Larkhall inside the Bath Conservation Area?
Most of Larkhall is outside the Conservation Area. The boundary is roughly along the River Avon — properties to the south and east of Larkhall are usually inside, Larkhall itself is to the north and outside. Tom will confirm for your specific property on the site visit.
My Larkhall Victorian terrace has a 10m garden — is that enough?
Yes — 10m gives you a 4×3m office (12m²) with comfortable access around the room. PD-sized room under 2.5m ridge is the easiest path.
Can I have a garden room with a toilet?
Yes — adding a small toilet to a garden room is straightforward, but it triggers Building Regulations (Part G sanitation). Most clients add a small composting toilet or connect to the main house drainage. Tom will tell you what's needed on the site visit.
What about a garden room with a shower?
Yes — adding a shower makes it full Building Regs territory (Part G). Most clients connect to the main house drainage with a small pump if the gradient is unfavourable. Tom works with a plumber for first-fix.
Are you VAT registered?
No — below the threshold. Quotes are VAT-free.
