What is a rooflight loft conversion?
A rooflight loft conversion (sometimes called a roof window conversion) keeps the existing roof shape and adds roof windows that sit flush with the slope. The floor is strengthened, a staircase is added and the space is insulated and finished.

Do you need planning permission for a rooflight loft conversion in Ammanford?
Whether you need planning permission depends on your house and its location in Wales. In Wales roof windows that sit close to the roof slope are generally permitted development outside protected areas.
The Party Wall etc. Act 1996 applies in Wales, so notices must be served before work on a shared wall, on the boundary, or excavation close to a neighbour’s foundations.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
