Do you need planning permission for a two-storey rear extension in Aberkenfig?
The planning route for a two-storey rear extension in Aberkenfig is set by Wales's householder rules and your council.
Welsh rules allow a two-storey rear extension without an application only where the ground floor is no deeper than 4 metres, the upper floor no deeper than 3 metres and at least 10.5 metres remains to the rear boundary. Most homeowners still apply for householder planning permission.
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 Aberkenfig like to extend?
Stone terraces along the valley floors and post-war semis higher up are typical of Aberkenfig. Sloping sites are common, so floor levels and retaining walls are designed at the start.
