The Olympic stadium for London鈥檚 2012 bid will require at least 拢250m of investment, according to project insiders.

The figure includes the money needed for infrastructure as well as construction costs.

It does not include the cost of redeveloping the rest of the Lea Valley site or any of the costs of the actual running of the games.

The London 2012 bid document, including projected costs, will be published today. The bid team would not confirm or deny the figure as 好色先生TV went to press.

Jason Prior, vice-president of architect EDAW, which led the Lea Valley masterplan team, would not comment on costs but said that the bid document did not differ greatly from the planning application.

He said the legacy team had been preparing a study on how much housing could be built in the area. It is already envisaging 11,000 houses by converting the Olympic village after the Games.
