Friedrichstrasse Office Building1921 - 1921
Although it was never built, Mies' design for the Friedrichstrasse Office Building remains one of the most important structures in 20th century architecture. For the Friedrichstrasse architecture competition, Mies ignored several rules dictated in the guidelines and presented a radical concept to the committee: a skyscraper made entirely of glass and steel. The design didn't win, much less receive an official mention. Decades later, this style has come to dominate corporate architecture.
