Knock down and rebuild in West Sussex

Covering West Sussex

We cover West Sussex, including Crawley, Worthing, Bognor Regis and Littlehampton, and the towns around them.

Homes in the South East

Housing across the South East mixes inter-war semis, post-war estates and older cottages in villages and market towns, so rear and side extensions, hip-to-gable lofts and garage conversions all come up regularly.

What do you get with a knock down and rebuild?

Knock down and rebuild means demolishing an existing house and building a new one in its place, often a bungalow or poorly built post-war house replaced by a larger, more efficient home. Because the new house counts as a new dwelling, the build is usually zero-rated for VAT.

How is a knock down and rebuild approved in West Sussex?

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?

A replacement dwelling is usually zero-rated for VAT where the old house is demolished completely to ground level.
Planning policy on replacement dwellings varies, especially in green belt and countryside.
