Covering Chiswick
Chiswick sits 6 miles west of London, with Acton 1 miles to the north-west and Barnes 1 miles to the south.
Homes in London
Much of London’s housing is Victorian and Edwardian terraces, which is why side return extensions, rear dormers and mansards are so common. Many streets are in conservation areas, and several boroughs use Article 4 directions that remove some permitted development rights.
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.
- Planning application for the replacement dwelling
- Demolition and site clearance
- Reconnection of services and landscaping

Planning and building rules in Chiswick
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 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.
- You will need somewhere to live for most of a year.
What are the steps?
- 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.
- 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.
What people ask before starting
Is it cheaper to knock down and rebuild or renovate?
It depends on the existing house. Where a house needs major structural work and a large extension, rebuilding can be similar cost and gives a better result. We compare both at feasibility.
What happens about asbestos?
An asbestos survey is done before demolition and any asbestos is removed safely first.
Can you visit a house in Chiswick 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.
