Olympic Games The London 2012 bid revealed a glimpse of its ambitious plans yesterday for the next-but-one summer Olympics.

The spectacular main stadium, designed by Spanish architect Alejandro Zaero-Pollo of the practice Foreign Office Architects, will be the centrepiece of a purpose-built Olympic park centred on the Lea Valley in east London.

The stadium, which Zaero-Pollo said was inspired by the human form, is one of a number of new venues which would be used alongside existing venues in London to stage the 28 Olympic sports.

The Olympic Park will also include an aquatic centre, velodrome, indoor sports arenas, training facilities and athletes' village. The organisers of the bid believe that the proximity of venues and facilities, combined with what they claim will be a seven-minute journey to central London, will make this site the most compact in the games' history.

The site will be at the heart of a new green space in the Lea Valley, the largest new urban park in Europe. Existing venues including the ExCel centre in Docklands, the Millennium Dome and Wembley Stadium would also stage events, as would Horse Guards Parade near Buckingham Palace and Richmond Park in the south-west of the capital.

London 2012 organisers will stress the sporting legacy of the new venues as they seek to win the votes of International Olympic Committee members. The Olympic stadium would be reduced in capacity to around 30,000 after the games and retained as a world-class athletics facility, something London does not have.

Bid organisers believe the "sporting legacy" argument contrasts with the bid put together by favourites Paris, which will largely use existing venues.

"We aim to end up with the best collection of sports facilities in Europe, maybe anywhere in the world," said the chairman of London 2012, Olympic medallist Sebastian Coe. "All in one area, in an extraordinary environment that not only meets the needs of local people, the wider London area and the south-east (of England) but which will also be a real boost to our international sporting achievements in the decades that follow."

Zaero-Pollo said: "In the design of the Olympic Park . . . we are not creating another Olympic village that is just a series of nice, white, modern buildings on a flat land. We are creating something that will grow out of the specific conditions and form of the Lea Valley. This will be part of the lasting legacy for the local community."
