Do you need planning permission for a kitchen-diner rear extension in Bargoed?
Whether your kitchen-diner rear extension in Bargoed needs a planning application depends on its size, your house and any local restrictions.
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 Bargoed like to extend?
Stone terraces along the valley floors and post-war semis higher up are typical of Bargoed. Sloping sites are common, so floor levels and retaining walls are designed at the start.

Do you handle building control in Bargoed?
Yes. We apply to the council or a registered approver under the Welsh regulations and hand over the completion certificate.

In Wales, usually yes if the extension is on or near a shared boundary or close to a neighbour's foundations. We serve the notices.
