Kitchen-diner rear extension in Briton Ferry
For homes in Briton Ferry, a kitchen-diner rear extension is often the simplest way to gain space without moving. An open-plan kitchen, dining and family room that opens straight onto the garden. We take it from survey to completion certificate.
Briton Ferry and its postcode districts SA10, SA11 and SA12 are part of our Swansea Bay coverage. For Briton Ferry kitchens we plan the extraction route and the island drainage before the slab is poured, so nothing has to be chased in later.

Do you need planning permission for a kitchen-diner rear extension in Briton Ferry?
The planning route for a kitchen-diner rear extension in Briton Ferry is set by Wales's householder rules and your council.
In Wales a single-storey rear extension can often be permitted development if it projects no more than 4 metres beyond the rear wall and is no more than 4 metres high. Wales has no prior approval route for deeper extensions, so anything bigger needs a householder planning application.
Conservation areas, National Parks and National Landscapes restrict permitted development in Wales, and listed buildings need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development or a householder planning application.
What are homes in Briton Ferry like to extend?
Older terraces near the centre and post-war semis further out are typical of Briton Ferry. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.

Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
