The organisation's boss, David Higgins, unveiling the changes to the park ( Revisions to Olympic Masterplan revealed) said the design work for the zone was well on track.
`We will be making planning applications for both the Games and legacy elements towards the end of this year,' he told a press conference yesterday.
'We've had detailed discussions on all of these plans with the five boroughs involved.'
'All the plans for the major building blocks have been agreed on in detail with the federations and organisations that will be using them in Games and legacy mode.
'This masterplan is as fixed as we can possibly make it. There may be some fine tuning in minor details,' he said.
Higgins also insisted that the games would be as environmentally-friendly as possible. 'The facilities will be constructed in low carbon and the Games will be zero waste - these are our environmental targets,' he added.
