Knock down and rebuild in Hampshire

Covering Hampshire

We cover Hampshire, including Southampton, Portsmouth, Basingstoke and Gosport, and the towns around them.

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?

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.

English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.

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.
Planning policy on replacement dwellings varies, especially in green belt and countryside.
