About Combe Down

What garden rooms typically look like in Combe Down

Combe Down gardens are significantly wider than central Bath's — the 1930s semis and post-war detached houses have 12–20m of usable rear garden depth. Slopes are common across the ridge, with terraced gardens stepping down from the houses. The wider plots here support larger garden rooms (15–25m²) than central Bath.

Honest note: The descriptions below are generalisations — what's typical or commonly found in Combe Down, 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 Combe Down

Combe Down properties are mixed — the village core (Victorian stone-built terraces) falls inside the Bath Conservation Area and needs planning, while the wider ridge (1930s semis, post-war detached) usually has PD rights intact. Tom will tell you on the site visit which side of the line your property sits on.

Common garden-room patterns in Combe Down

Common Combe Down garden room patterns: 5×4m garden studios (20m²) on the wider 1930s semi rear gardens, 4×4m garden offices (16m²) on the more modest plots, occasional larger garden annexes (25m²+) for dependent relatives on the bigger detached houses. Most ridge-top jobs qualify for PD because of the wider plot sizes, but the village core jobs need planning.

Local questions

Combe Down — common questions

My Combe Down 1930s semi has a 15m garden — is that enough for a big studio?
Yes — 15m of rear garden depth gives you a 5×4m studio (20m²) with comfortable access around the room. Most Combe Down 1930s semi garden rooms are PD-sized and need no application.
We're in the Combe Down village core — does the Conservation Area affect garden rooms?
Yes — the Combe Down village core (the Victorian stone-built terraces) is inside the Bath Conservation Area, so any garden room over the standard PD limits will need a planning application. Most village core jobs are smaller because the gardens are tighter.
Our garden is on a slope — can you build on a slope?
Yes — sloping gardens are common on the ridge. We usually work with the existing levels, sometimes building on a low retaining wall or beam foundation. Ground screws (instead of concrete pads) work well on slopes. Tom will tell you the best foundation approach on the site visit.
Can we have an annexe for a dependent relative?
Yes — Combe Down'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.
Are you VAT registered?
No — below the threshold. Quotes are VAT-free.

Every job follows the same six stages. Some are quicker, some are slower — but the order and what to expect at each point is fixed, so you're never wondering what's happening.

  1. 01

    Planning check

    Most garden rooms fall under permitted development. We confirm this for your specific site and flag any conservation-area or listed-building complications up front.

  2. 02

    Design and quote

    Size, position on the plot, intended use, services needed. Fixed-price quote.

  3. 03

    Foundations

    Ground screws or concrete pad, depending on ground conditions. Usually a single day.

  4. 04

    Frame and roof

    Timber frame raised, roof fitted, windows and doors installed. Most rooms take 1–2 weeks on site.

  5. 05

    Insulation and cladding

    Insulation fitted to target U-values (roof below 0.20, walls below 0.25, floor below 0.22). External cladding applied.

  6. 06

    Interior finish

    Lining board, flooring, electrics (first-fix and final). Snagging and sign-off.
