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 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.

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

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

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