The design of the media facilities has been described as innovative
Plans for the £355m Olympic broadcast and media centre to become a business hub have been unveiled.
The International Broadcast and Main Press Centres (IBC/MPC) will support about 20,000 broadcasters, photographers and journalists.
But after the London 2012 Games the IBC/MPC is to provide just under 900,000 sq ft of business space.
Planning applications for the media centre have been submitted this week, the Olympic Delivery Authority said.
The authority's chairman John Armitt described the proposed business hub as an "innovative design" that can switch to being a "flexible and green employment space for a range of potential business uses" after the Games.
It is hoped that designs including the recycling of 60% of non-drinking water collected across the Olympic Park and new habitats to attract wildlife will make the IBC/MPC an eco-friendly facility after 2012.
London 2012 organising committee chairman Lord Coe said: "Billions of people around the world rely on the international media to relay the stories of human endeavour on the field of play and to capture the atmosphere at Games time.
"The impressive facilities we have planned will give us the best possible foundations for the media to tell all the stories from the London 2012 Games while leaving high performance workspace in legacy for the east of London."
Hackney Mayor Jules Pipe wants the IBC/MPC to become a hub for the digital, media and creative industries after the Games.
He said: "Local businesses and media companies have expressed strong interest in moving to the facilities in legacy, and we will continue to work to secure the best possible legacy for our borough, residents and local businesses."
Tom Russell, group director for Olympic legacy at the London Development Agency, echoed this view but added that it could also have some higher educational use.
