Covering Heston
Our coverage around Heston (TW5) also includes Hounslow (1 miles to the south-east) and Isleworth.
Homes in London
Terraced houses dominate many London neighbourhoods, so most projects involve shared walls, narrow access and a party wall process. Conservation areas are widespread, and some boroughs have their own mansard and basement guidance.
What goes into 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
- Demolition and site clearance
- New foundations, structure and full fit-out

Do you need permission for a knock down and rebuild in Heston?
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 Heston homeowners check first?
- 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?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- 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.
