Georgian squares, Victorian terraces and hillside streets
Kennington and Vauxhall are Georgian and early-Victorian, with small walled gardens and basement lightwells behind tall terraces. Clapham, Brixton and Stockwell are classic Victorian terrace on largely level ground with long thin rear plots. South of there — Herne Hill, Tulse Hill, West Norwood, Streatham — the ground rises towards the Norwood ridge, and the gardens rise with it: it is common to find a rear plot climbing two metres or more, often in a single tired bank with rotting sleepers at the bottom. That is a structural project, not a planting one.
