Do you need planning permission for a bungalow rear extension in Briton Ferry?
The planning route for a bungalow rear extension in Briton Ferry is set by Wales's householder rules and your council.
Welsh permitted development allows a single-storey rear extension of up to 4 metres in depth and 4 metres in height, subject to boundary and garden-coverage limits. There is no larger-extension prior approval scheme in Wales.
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 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.
