This week Jahn completed the 1000M skyscraper in Chicago

This week on Dezeen, the 1000M skyscraper designed by architecture studio Jahn was unveiled in Chicago.
Located at the south end of the Michigan Avenue Historic District, the 223-metre-tall skyscraper features two distinct sections comprised of a large base finished with aluminium panels and a longer, glossy top.
The structure, which is one of the last projects designed by the studio's late founder Helmut Jahn, is now one of the tallest residential skyscrapers in the city.
