Housing policy over the last 40 years has left a generation of people living in "apartheid cities" according to the Fabian Society.
It contrasts their experience with the first post-war generation which, it says, lived in public housing without stigma or a loss of opportunity. Now, it says, tenants in crumbling estates are isolated from the rest of society.
Simon Thomson speaks to Sheila and Allan Harris who have lived on the Tavy Bridge estate in Thamesmead since 1970. Allan is a member of the residents' association and both are in their 70s.
Tavy Bridge's cutting edge design was used as a backdrop for the Stanley Kubrick film Clockwork Orange and is now undergoing a multi-million pound regeneration project.
