Damp, mould and leaks across south west London
South west London, for our purposes, is the three boroughs between the Thames and the Surrey border: Kingston upon Thames, Richmond upon Thames and Wandsworth. Kingston is an ancient market town on the river where Saxon kings were crowned; Richmond is the only borough that sits on both banks of the Thames and is full of conservation areas; Wandsworth stretches from Battersea’s riverside through Clapham Junction, Balham, Putney and Tooting.
The housing runs from listed Georgian terraces and Victorian villas to inter-war semis, mansion blocks, council estates and new riverside towers, and each brings its own failure pattern. Below, every borough links to its own page and to the towns and neighbourhoods within it that have a page of their own.
