Two-storey rear extension in Brixton
For homes in Brixton, a two-storey rear extension is often the simplest way to gain space without moving. A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. We take it from survey to completion certificate.
Brixton sits in Greater London, with postcode districts including SE5, SE24 and SW9. In Greater London we check the neighbours' rear windows first, because the upper floor is where most two-storey schemes win or lose planning.

Do you need planning permission for a two-storey rear extension in Brixton?
Whether your two-storey rear extension in Brixton needs a planning application depends on its size, your house and any local restrictions.
England's rules allow a rear extension of more than one storey without an application only when it is no deeper than 3 metres and at least 7 metres from the boundary opposite the rear wall, and never on designated land. Most two-storey schemes need householder planning permission.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Brixton like to extend?
Period terraces in Brixton sit alongside flats, and the difference matters: houses usually keep permitted development rights, while flats and maisonettes need planning permission for any rear extension.
