2008, "London Bowl" creative architect Philips Jensen went to Beijing to attend a venue test. He said it was like the Olympic venues in Beijing, but did not mean to continue like Beijing then do. Beijing Olympic great many people in the UK through the Beijing Olympics suddenly have a general understanding of Beijing, this may be a great advertising in Beijing and China, "he said," But in London, we hope to show the city itself, so London will be more use of temporary venues and the Olympic Park will not become too much focus Imagine triathlon race route after Buckingham Palace, the beach volleyball venue is located in the prime minister living in Downing Street near ... London is known these places when all the attractions - Westminster Abbey, Big Ben, the London Eye, Greenwich Park will be garishly illuminated, is expected then comments and media reports London how as a whole to host the Olympics, and not only focus on the Olympic venues. "
Jason London Olympics brought a new way of thinking - to explore the relationship between permanent and temporary.
"it is clear that the rich countries of the world can spend a lot of money to organize such a large event in the Olympic Games, but to my understanding, the IOC wants to do is hope that the Olympic Games to further spread the Olympic idea to do this little way is not to build too many permanent buildings, or at least into the temporary building part, London has already begun this process, or perhaps more than ever before to do. "
Jensen seems budget constraints, but this constraint has also become an opportunity to inspire a variety of innovative ideas and practices. "You can not make the roof lighter than this form, only use so little material, and has contributed to the sustainable development." He said.
because the wide, narrow shape, stadium nicknamed "London Bowl" this "bowl" acclaimed primary reason is the use of the largest in the history of the temporary stands, 80,000 seats, only 25,000 fixed seats, the upper part of 55,000 seats are removable, and greatly reduced maintenance costs. Departure from sustainability, after the end of the Olympic Games, where you can quickly slimming Stadium is a medium-sized communities. "The capacity of the stadium can not originally planned downsizing so powerful, according to the needs of 60,000 seats reserved, so there is the ability to organize different events, such as soccer, rugby and even cricket and other sports competitions, also can do the concert." Jensen said.
, LOCOG stressed, this unique design has the significance of the "the Olympic milestone" style, will leave a valuable legacy for the Olympic history. Shi Yade, the main designer of the venues, with previous Olympic venues before compared, design the stadium removable, originality, and forward-looking. He said: "This is not the kind of win in spectacular shape Stadium, but this is a smarter building will be more focus on practicality stadiums become a truly intelligent, sustainable development." It has a complex loading and unloading works like a large bowl filled with air to ensure that after the game effectively utilized.  compare the night sky
