Timber Extensions in Henleaze

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.

About Henleaze

What extensions typically look like in Henleaze

Henleaze is dominated by 1930s semis with 12–18m rear gardens, often with back-lane access. Most properties are outside the Bristol conservation areas and qualify for PD rights on standard rear extensions.

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

Typical property types

  • 1930s semis (3-bed, larger than Bedminster)
  • Some larger detached houses

Planning & permissions

The planning context in Henleaze

Most Henleaze extensions qualify for Permitted Development because the properties are outside the Bristol conservation areas. Tom will tell you on the site visit whether PD applies for your specific extension.

Common extension patterns in Henleaze

Common Henleaze extension patterns: 5–6m single-storey rear extensions on the 1930s semis, wraparound extensions combining rear + side-return, and (on the larger detached houses) two-storey rear extensions. Most extensions use timber cladding or render carrier.

Local questions

Henleaze — common questions

Is Henleaze inside any Bristol Conservation Area?
No — Henleaze is outside all Bristol conservation areas. Most Henleaze extensions qualify for Permitted Development.
My Henleaze 1930s semi has a 15m garden — is that enough for a 6m extension?
Yes — 15m gives you a 6m single-storey rear extension comfortably, with 9m of garden remaining. PD-friendly for a 4m rear extension on an attached house; 6m would need neighbour consultation under PD but is usually approved without a full application.
Can I extend my Henleaze property with a wraparound extension?
Yes — wraparound extensions are common on Henleaze's wider 1930s semi plots. Most wraparounds need a planning application because they exceed the PD limits for side extensions, but Henleaze is outside the Conservation Area so applications are usually approved within 8 weeks.
How much does a Henleaze timber extension cost?
Henleaze extensions are typically cheaper than Clifton's. Rough guide: single-storey rear extension on a 1930s semi — £35,000–£50,000; wraparound extension — £55,000–£80,000. Tom gives fixed-price quotes after the site visit.
Are you VAT registered?
No — below the threshold. Quotes are VAT-free.

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.
