Four years ago, Beijing flexed its architectural might and forever changed what we expect from a host city. And immediately after the closing ceremonies we questioned if anyone could ever live up to their accomplishments. But instead of attempting to upstaging Beijing, London choose to think long-term. With sustainability being a main theme of the 2012 Olympics, the plan was to only make permanent structures that will have long-term use after the Games, while building temporary structures for everything else that will be utilized during the ceremonies. And while Beijing’s venues will still sit largely unused, London’s will either be dismantled and recycled or become part of the England’s largest urban park.
