FLATS being built on the site of a former council estate are going on sale for more than £500,000 each,  housing activists revealed yesterday. 

A yet-to-be-built studio flat on the grounds of the one-time Heygate Estate in the London borough of Southwark was put on sale online yesterday for £515,000. 

The demolition of the estate and its sale to property developers Lend Lease was highly criticised by residents and local campaigners.
