Timber Extensions
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.

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.
- 01
Planning conversation
Conservation area? Listed building? Permitted development likely to apply? We confirm before any drawings.
- 02
Architect drawings
If planning is needed, an architect produces the drawings for the application. If permitted development, drawings go straight to building regs.
- 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.
- 04
Foundations and groundworks
Excavation, footings, slab. Usually a separate contractor; we coordinate the schedule.
- 05
Frame raised
Pre-made timber frame delivered and erected on site, typically in a single day.
- 06
Roof, sheathing, externals
Roof structure fitted, walls sheathed, breathable membrane and external cladding applied.
- 07
Internals
Studwork, insulation, first-fix for services. Plasterboard and finishes follow.
