Covering Bridgend
We work in Bridgend (CF31) and the places around it, including Porthcawl, Cowbridge and Llantwit Major.
Homes in Mid Glamorgan
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 goes into 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
- Asbestos survey, demolition notice and service disconnections
- New foundations, structure and full fit-out

Planning and building rules in Bridgend
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.
What should Bridgend 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 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.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
