Appearing to float on the Waterworks River in London and in front of the Olympic Stadium and Aquatics Center is the BMW Pavillion. Water from the river flows down the facade of the building, cooling it and ensuring that its surface constantly changes. The water is then filtered and circulated back into the river. The pavillion's lower floor is dedicated to the future of personal transport, while the 9 rooftop pavillions show upcoming BMW Group vehicles. [Contemporist]
