Leeser Architecture designed an iconic structure to act as the central pavilion for the 2012 Olympics in London.  The program includes amphitheaters, public gathering spaces, as well as a digitally controlled waterfall. 

This structure will provide a place for families to visit, both tourists and locals, providing breathtaking views over the Olympic Park as well as over London in the distance. There are no visible borders or edges which gives visitors the sensation of being elevated upon a cloud, one feels suspended above the vast expanses of the Olympic Park. 

Utilizing the large amounts of rain London receives each year, the edge of the Floating Lake contains computer controlled water nozzles that allow for a continuous patterned waterfall spanning the complete perimeter, giving the appearance of the lake overflowing its edge. The space below is well suited for casual concerts, performances or street theater.
