Covering High Wycombe
We work in High Wycombe (HP13) and the places around it, including Beaconsfield, Amersham and Maidenhead.
Homes in the South East
Housing across the South East mixes inter-war semis, post-war estates and older cottages in villages and market towns, so rear and side extensions, hip-to-gable lofts and garage conversions all come up regularly.
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.
- Feasibility: rebuild versus extend and renovate
- Planning application for the replacement dwelling
- Reconnection of services and landscaping

What approvals does a knock down and rebuild need in England?
Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.
This needs full planning permission from the council.
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.
- You will need somewhere to live for most of a year.
How does the project run?
- 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.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
