Wrap-Around Extensions in London

A wrap-around extension fills the side return and extends out at the back, giving the biggest ground-floor space a terraced house can get. It is a bigger structural job, so the steel design and planning matter.

Questions we're often asked

How long does it take?

Longer than a single extension because of the extra steelwork. You get a programme with your quote.
