Planning and building regulations in West Glamorgan
Whether you need planning permission depends on your house and its location in Wales. In Wales applications go to the local planning authority, and building control can be the council or a registered building control approver.
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.
We check this for your address before design work starts, so there are no surprises later.
