Planning and building rules in Cwmbran
Planning decisions in Wales are made by the local council, using permitted development rules set by the Welsh Government rather than England’s. Building regulations in Wales have their own approved documents, and the Party Wall etc. Act 1996 applies to work on shared walls and boundaries.
Internal work like this does not usually need planning permission in Wales unless the building is listed. Building regulations approval is needed for the structural work.
What can change the price or programme?
- The beam size can mean a downstand in the ceiling unless it is set flush within the floor.
- Pipes and cables in the wall need rerouting first.
