Do you need planning permission for a kitchen-diner rear extension in Rhondda?
The planning route for a kitchen-diner rear extension in Rhondda is set by Wales's householder rules and your council.
The Welsh Government's householder rules let many homes add a single-storey rear extension up to 4 metres deep and 4 metres high without a planning application. Deeper projects go through a householder application, because Wales has no prior approval route.
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?
Stone terraces along the valley floors and post-war semis higher up are typical of Rhondda. Sloping sites are common, so floor levels and retaining walls are designed at the start.
