Do you need planning permission for a bungalow rear extension in Porthcawl?
Planning for a bungalow rear extension in Porthcawl follows the Welsh householder rules.
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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Porthcawl like to extend?
Stone terraces along the valley floors and post-war semis higher up are typical of Porthcawl. Sloping sites are common, so floor levels and retaining walls are designed at the start.
