Single Storey Rear Extensions in London
A single storey rear extension is the most common way to get a bigger kitchen or living room without moving. We build the extension and fit it out, so one team is responsible from foundations to finished floor.

Questions we're often asked
Do I need planning permission?
Many rear extensions fall under permitted development or the prior approval scheme. Conservation areas and flats usually need full planning.
Can we keep using the kitchen?
Usually until the last few weeks, when the old back wall comes out.
