Knock down and rebuild in Sevenoaks

Covering Sevenoaks

Our coverage around Sevenoaks (TN13) also includes Tonbridge (6 miles to the south-east) and Swanley.

Homes in the South East

The South East has a lot of 1930s and post-war semi-detached housing, well suited to rear extensions and hip-to-gable loft conversions, alongside period properties in conservation areas that need a more careful design.

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.

Do you need permission for a knock down and rebuild in Sevenoaks?

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. We prepare the drawings and supporting documents, submit the application and respond to the planning officer.

What can change the price or programme?

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.

Knock down and rebuild: common questions

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.

Is VAT charged on a knock down and rebuild?

Usually not on the new house, if the old one is demolished completely and the new building is a qualifying dwelling.

Can you visit a house in Sevenoaks 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.
