UK Minister for Housing Yvette Cooper has announced an £8bn fund to build affordable homes and pledged to boost social housing stock.
Cooper says social housing building rates will rise from 30,000 homes a year to 45,000 by 2010, eventually reaching a target of 50,000.
She told the Labour Party conference in Bournemouth the rules will be changed to make it easier for councils to build more homes.
"Never again should we tolerate the housing apartheid that decades of new development delivered in Britain," she said.
"Today we must pledge to build truly mixed communities. You should walk down the street and have no idea which door is private, which is social housing or which is a key worker starter home."
