What is a house renovation?
A house renovation brings an older or tired home up to date. It can include rewiring, a new heating system, replastering, new floors, windows, kitchens and bathrooms, and changes to the layout. A full renovation is often combined with an extension or loft conversion.

Do you need planning permission for a house renovation in Cwmbran?
Here is how the rules work for a house renovation in Wales. In Wales internal renovation usually does not need planning permission unless the house is listed. Notifiable work must meet building regulations.
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.
