Timber Extensions in Westbury-on-Trym & Stoke Bishop

Timber frame extensions — typically cheaper and faster than traditional blockwork, with the same building-regs compliance. TM Carpentry handles the structural carpentry side: frame, roof structure, sheathing and external cladding. Building regs apply regardless of construction method, and Bath has a lot of conservation-area properties where permitted-development rights don't apply. Available across Bath, Bristol and Keynsham — see the areas covered for specific neighbourhoods.

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 extensions here qualify for Permitted Development.
My Westbury-on-Trym detached house has a 20m garden — is that enough for a large extension?
Yes — 20m gives you a 6m single-storey rear extension comfortably, with 14m of garden remaining. PD-friendly for a 4m rear extension on a detached house; 6m would need neighbour consultation under PD but is usually approved without a full application. Tom will tell you on the site visit.
Can I extend my Westbury-on-Trym property with a two-storey extension?
Yes — two-storey rear extensions are common on Westbury-on-Trym's larger detached plots. Most two-storey extensions need a planning application because they exceed the PD limits. Bristol City Council typically approves them within 8 weeks.
How much does a Westbury-on-Trym timber extension cost?
Westbury-on-Trym extensions are typically cheaper than Clifton's. Rough guide: single-storey rear extension on a detached house — £40,000–£60,000; two-storey extension — £70,000–£100,000. Tom gives fixed-price quotes after the site visit.
Are you VAT registered?

Our step by step process

Our step by step process

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 conversation

    Conservation area? Listed building? Permitted development likely to apply? We confirm before any drawings.

  2. 02

    Architect drawings

    If planning is needed, an architect produces the drawings for the application. If permitted development, drawings go straight to building regs.

  3. 03

    Quote and frame order

    Fixed-price quote for our scope. Factory frame order placed once drawings are signed off — 4–8 week lead time.

  4. 04

    Foundations and groundworks

    Excavation, footings, slab. Usually a separate contractor; we coordinate the schedule.

  5. 05

    Frame raised

    Pre-made timber frame delivered and erected on site, typically in a single day.

  6. 06

    Roof, sheathing, externals

    Roof structure fitted, walls sheathed, breathable membrane and external cladding applied.

  7. 07

    Internals

    Studwork, insulation, first-fix for services. Plasterboard and finishes follow.
