A good extension shouldn't look bolted on. It should feel like it was always meant to be there. That comes down to getting the structure right and then finishing it so the join between old and new disappears — matched floors, level ceilings, and openings that line through cleanly.
We handle the carpentry and joinery for single and double-storey extensions across East Kilbride and the surrounding towns, from the structural timber through to the last architrave. If you're coordinating other trades, we're straightforward to work alongside.
Scope
What an extension typically involves
- Structural timber, floor joists and roof carpentry
- Forming new openings and steel/timber support work
- Studwork, insulation battening and first fix
- Doors, skirtings, architraves and second fix finishing
- Bi-fold and French door installation
- Matching in with the existing house so it flows

Common questions
Extensions, answered
Do I need planning permission for an extension?
It depends on the size and your property — many fall under permitted development, but not all. We can point you in the right direction, though your architect or the local authority confirms the specifics.
Can you fit bi-fold or French doors?
Yes — supply and fit, or fit doors you've sourced. Getting these dead level is where the quality shows, and it's something we take seriously.
How long does an extension take?
It varies with size and spec, but we'll give you a realistic timescale in the quote and keep you updated against it as the job runs.
