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.
