Do you need planning permission for a wraparound extension in Abertillery?
Here is how the rules in Wales apply to a wraparound extension in Abertillery.
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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Abertillery like to extend?
Stone terraces along the valley floors and post-war semis higher up are typical of Abertillery. Sloping sites are common, so floor levels and retaining walls are designed at the start.

FAQ
Wraparound extension questions in Abertillery
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.
Can you match the brick or stone on my Abertillery house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
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.
Do you handle building control in Abertillery?
Yes. We apply to the council or a registered approver under the Welsh regulations and hand over the completion certificate.
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
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.
