Covering Monmouth

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 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.
- Feasibility: rebuild versus extend and renovate
- Demolition and site clearance
- Reconnection of services and landscaping

What approvals does a knock down and rebuild need in Wales?
Welsh projects need planning clearance from the council under Welsh rules, building regulations approval under the Welsh approved documents, and party wall notices where the work affects a neighbour’s wall or foundations.
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?
- 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.
What are the steps?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- 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.
