Wraparound extension in Rhondda

For homes in Rhondda, a wraparound extension is often the simplest way to gain space without moving. An L-shaped extension that fills the side return and runs across the back. We take it from survey to completion certificate.

We cover Rhondda (CF40, CF41 and CF43) as part of our South Wales Valleys work. Wraparound projects around Rhondda often involve two neighbours, so we start the party wall conversations early.

Do you need planning permission for a wraparound extension in Rhondda?

Here is how the rules in Wales apply to a wraparound extension in Rhondda.

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 Rhondda like to extend?

Rhondda is largely terraced streets on sloping ground, where back gardens step up or down from the house. Excavation, retaining walls and drainage are priced at the survey.
