The deal was signed in the last 48 hours, the two sources said. It has been reported that a successful bid for the Olympic Village would have to be at least 500 million pounds ($811 million). 

The 27-hectare athlete’s village deal includes 1,400 homes and six other plots, which Delancey and Qatari Diar will develop as part of a wider urban regeneration scheme in the district when the games finish next year.

Delancey and Qatari Diar beat a rival bid from Hutchison Whampoa, which is Hong Kong billionaire Li Ka-shing’s flagship ports-to-telecommunications conglomerate.

They also beat a 1 billion pounds proposal from the Wellcome Trust to take over all the 2.5-kilometer-square Olympic park.

An official announcement is expected in the next few days.

On July 28, UK developer Canary Wharf Group and Qatari Diar said they had won a 300 million pounds deal to redevelop the Shell Center in London.  

The companies would each contribute 150 million pounds to develop a 5.25-acre office, residential and retail scheme around a 27-story tower that contains Royal Dutch Shell’s London headquarters and which the oil major will still own.
