Knock down and rebuild in Caerphilly

Covering Caerphilly

Our coverage around Caerphilly (CF83) also includes Whitchurch (4 miles to the south) and Pontypridd.

Homes in Gwent

Welsh homes include long terraces built into hillsides, stone cottages and modern estates, and sloping sites often shape how and where an extension can go.

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.

How is a knock down and rebuild approved in Caerphilly?

In Wales the planning rules, including what counts as permitted development, are set by the Welsh Government, and Welsh building regulations differ in places from England’s. We check both against your house before drawings are finalised, and handle party wall notices where needed.

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 I think about before starting?

You will need somewhere to live for most of a year.
Asbestos is common in post-war houses and must be removed by licensed contractors where required.
