Working in Bridgend
Our survey diary covers Bridgend, including CF31, CF35. The same team covers Porthcawl (6 miles), Maesteg (8 miles), Tonypandy (10 miles), Rhondda (12 miles), all within easy reach.
Just over the South Glamorgan border, Cowbridge is about 6 miles away. Welsh housing ranges from stone terraces in the valleys to render-and-slate houses and modern estates, and the Welsh planning rules differ from England's in several places.

Will the council need to approve it?
In Wales a single-storey rear extension can usually project up to 4 m beyond the rear wall without a planning application, if it is no more than 4 m high, keeps eaves to 3 m and overall height to 4 m within 2 m of a boundary, and covers no more than half the land around the original house. Wales has no larger home extension prior approval scheme.
In a conservation area, national park, National Landscape or World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.
Building over or within 3 m of a public sewer needs the water company's consent before the foundations go in.
Applications are decided by the local planning authority (your county or county borough council, or the national park authority).
Included in a typical project
- Breathable wall build-up with insulation
- Fire and acoustic details where needed
- Foundations, often lighter than masonry
- Frame design and structural calculations
Moisture is the enemy of any timber building. We design ventilated cladding cavities, breather membranes and a proper damp-proof course height, and keep the frame dry during construction.

Build and sign-off
Our team builds the extension, keeps you updated weekly and finishes with building control sign-off.
Timber frame extension questions answered
How long does a timber frame extension take to build in Bridgend?
On site, typically 8 to 14 weeks once approvals are in place. Before that, allow 4–12 weeks design and approvals.
Do you cover all of Bridgend?
Yes. We cover Bridgend and the surrounding parts of Mid Glamorgan. Site visits are free and there is no obligation.
Who do I contract with for a timber frame extension in Bridgend?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Is timber frame cheaper than brick?
It is similar overall. The frame can save time on site, but the cladding choice has a big effect on cost. Our guide range is about £1,630 to £3,160 per m² including VAT.
Does a timber frame extension need planning permission?
The same planning rules apply as for any extension. If the cladding looks different from the house, permitted development’s matching-materials condition may mean an application is needed.
