Southwark Council has launched the search to find a development partner for the 3,500-home regeneration of the Aylesbury Estate.
A notice in the Official Journal of the European Union proposes a 20-year development agreement with the potential to extend for a further 10 years, Estates Gazette reported.
It said the authority had switched from its original plan of regenerating the estate in nine stages - for which London & Quadrant were selected for the first two - to a development-partner model for the remaining work.
The move would follow similar lines to Southwark’s agreement with Lend Lease for the £1.5 billion regeneration of Elephant & Castle.
"We've already surpassed one degree of global warming," said Kristen Buida, manager of the London Climate Change Partnership.
