Planning and approvals in Briton Ferry
In Wales a wraparound must satisfy both the rear and side extension limits to be permitted development, so most need a planning application to the council.
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.
The Party Wall etc. Act 1996 applies in Wales as in England: notice must be served before work to a shared wall, building on the boundary, or excavating close to a neighbour's foundations.
Building regulations approval is separate from planning. Wales has its own building regulations and approved documents; the council or a registered building control approver checks the plans, inspects the work and issues a completion certificate.
Applications are decided by the local planning authority (your county or county borough council, or the national park authority).

Extensions in and around Briton Ferry
Across SA12, we can visit, measure and advise. Neighbouring towns we cover include Neath (2 miles), Clydach (5 miles), Swansea (5 miles), Gorseinon (10 miles).
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.

Build and sign-off
The build is managed from start to finish, inspected at each stage and signed off on completion.
Common questions in Briton Ferry
Who do I contract with for a wraparound extension in Briton Ferry?
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.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Briton Ferry, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do I need building regulations approval in Briton Ferry?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Will I need to move a drain?
Often. Side returns frequently contain a manhole or a shared drain. Building near or over a public sewer needs the water company’s consent in England and Wales, which we arrange.
Is a wraparound better than a side return alone?
It adds far more space, but costs more and needs planning permission more often. Our comparison guide sets the two side by side.
