The Shard of Glass will be completed in 2012 and it will officially be the largest building in the European Union at 310 meters, including 72 floors of residential and commercial properties. The top floor will be an observation gallery and open air viewing deck.
Designed in 2000 by Renzo Piano, the Shard will be almost entirely made of glass. Renzo's artistic use of triangular panes of glass will reflect sunlight and shade in such a way that the building will change it's appearance with the passing of each season.
Once completed the Shard should be an impressive sight to behold.
