London Gate, Commissioned to celebrate the London 2012 Olympics

This winning entry by studio Donis is a 100 metre-tall structure to celebrate the London 2012 Olympic and Paralympic games. Named 'London Gate' the structure is designed as a temporary landmark and has been commissioned to be placed in Aldgate, east London from January 2012. Donis is an architecture studio based in Rotterdam and managed to come first in 'A landmark for Aldgate' international design competition, which included around 100 entries. The structure includes a glass elevator, very scary if you ask me.
