What is a bungalow loft conversion?
A bungalow loft conversion uses the large roof space of a bungalow to add bedrooms and a bathroom, turning it into a chalet bungalow. Dormers at the front, rear or both create headroom; some projects raise the roof entirely.

Do you need planning permission for a bungalow loft conversion in Cwmbran?
Here is how the rules work for a bungalow loft conversion in Wales. In Wales rear dormers may be permitted development within volume limits; front dormers and roof raises need planning permission.
Building regulations in Wales are set by the Welsh Government. Approval comes from the council’s building control service or a registered building control approver, with inspections during the work and a completion certificate at the end.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
