We take on knock down and rebuild in Feltham as a complete project: survey, drawings, planning or permitted development checks, building control and the construction itself.

Covering Feltham

We work in Feltham (TW13) and the places around it, including Hanworth, Ashford and Hounslow.

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 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.

  • Asbestos survey, demolition notice and service disconnections
  • Demolition and site clearance
  • 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. We prepare the drawings and supporting documents, submit the application and respond to the planning officer.

What can affect a knock down and rebuild?

  • 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.

How does the project run?

  1. Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
  2. Site visit. We walk the plot or existing house, look at access, levels, services and boundaries, and talk through what could be built.
  3. Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
  4. Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
