House Extensions in Lambeth — what to expect
Lambeth extensions are mostly rear additions on Victorian terraces in SW9 and SE11. Conservation areas around Stockwell, Kennington and parts of Brixton restrict permitted development. The quality expected in this market is high — Lambeth buyers invest seriously in their properties.
