Wraparound extension in Briton Ferry
Thinking about a wraparound extension in Briton Ferry? An L-shaped extension that fills the side return and runs across the back. Our team handles the drawings, the planning route and the build, and your contract is with one company throughout.
We cover Briton Ferry (SA10, SA11 and SA12) as part of our Swansea Bay work. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in Swansea Bay where a side return alone would leave the room too narrow.

Ground conditions, glazing, the roof and how far the house is opened up move the final figure within the range.
Do you need planning permission for a wraparound extension in Briton Ferry?
Whether your wraparound extension in Briton Ferry needs a planning application depends on its size, your house and any local restrictions.
Welsh side-extension rules limit a single-storey side addition to 4 metres high and a 50% increase in the width of the original house, with tighter limits in conservation areas. Wraparounds usually need a planning application.
In Wales, as in England, the Party Wall etc. Act 1996 requires notice to neighbours before work to a shared wall or excavation near their foundations.
Conservation areas, National Parks and National Landscapes restrict permitted development in Wales, and listed buildings need listed building consent. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
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.

FAQ
Wraparound extension questions in Briton Ferry
Do I need a party wall agreement?
In Wales, usually yes if the extension is on or near a shared boundary or close to a neighbour's foundations. We serve the notices.
Is the site visit in Briton Ferry free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Will it take a lot of garden?
Less than a deep rear extension of the same area, because part of the space comes from the side passage.
Can you match the brick or stone on my Briton Ferry house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
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.
Do you handle building control in Briton Ferry?
Yes. We apply to the council or a registered approver under the Welsh regulations and hand over the completion certificate.
