What do you get with a knock down and rebuild?
Knock down and rebuild means demolishing an existing house and building a new one in its place, often a bungalow or poorly built post-war house replaced by a larger, more efficient home. Because the new house counts as a new dwelling, the build is usually zero-rated for VAT.
- Planning and building regulations checks under Welsh rules
- Feasibility: rebuild versus extend and renovate
- Asbestos survey, demolition notice and service disconnections

Do you need permission for a knock down and rebuild in Ystalyfera?
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 Ystalyfera homeowners check first?
- A replacement dwelling is usually zero-rated for VAT where the old house is demolished completely to ground level.
- Planning policy on replacement dwellings varies, especially in green belt and countryside.
What happens after I enquire?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- Site visit. We walk the plot or existing house, look at access, levels, services and boundaries, and talk through what could be built.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
What people ask before starting
Is it cheaper to knock down and rebuild or renovate?
It depends on the existing house. Where a house needs major structural work and a large extension, rebuilding can be similar cost and gives a better result. We compare both at feasibility.
What happens about asbestos?
An asbestos survey is done before demolition and any asbestos is removed safely first.
Who deals with the council for a project in Ystalyfera?
We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
