What is a knock down and rebuild?

We assess whether rebuilding is better value than extending and renovating, prepare the planning application for the replacement dwelling, manage the demolition notice and asbestos survey, then build the new home. The process runs much like a new build once the old house is cleared.

What approvals does a knock down and rebuild need in Wales?

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.

This needs full planning permission from your council in Wales. We prepare and submit the application and deal with the planning officer on your behalf.

What should Cwmbran homeowners check first?

A replacement dwelling is usually zero-rated for VAT where the old house is demolished completely to ground level.
Asbestos is common in post-war houses and must be removed by licensed contractors where required.
