Knock down and rebuild in Hounslow

Covering Hounslow

Alongside Hounslow, we also cover Isleworth, Heston (1 miles to the north-west) and Richmond.

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.

What approvals does a knock down and rebuild need in England?

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.

This needs full planning permission from the council.

What should I think about before starting?

You will need somewhere to live for most of a year.
Asbestos is common in post-war houses and must be removed by licensed contractors where required.

How does the project run?

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.
Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.

Yes, for the replacement dwelling.

What happens about asbestos?

An asbestos survey is done before demolition and any asbestos is removed safely first.

Can you visit a house in Hounslow 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.
