Covering Brecon
We work in Brecon (LD3) and the places around it, including Merthyr Tydfil, Ebbw Vale and Builth Wells.
Because Powys covers a wide area, we confirm availability after the first call and include any travel costs in the written quote rather than adding them later.
Homes in Powys
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.
- Planning application for the replacement dwelling
- Demolition and site clearance
- New foundations, structure and full fit-out

Do you need permission for a knock down and rebuild in Brecon?
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 I think about before starting?
- You will need somewhere to live for most of a year.
- 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.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
Knock down and rebuild: common questions
Is VAT charged on a knock down and rebuild?
Usually not on the new house, if the old one is demolished completely and the new building is a qualifying dwelling.
Do I need planning permission?
Yes, for the replacement dwelling.
Can you visit a house in Brecon to quote?
Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
