860–880 Lake Shore Drive

860–880 Lake Shore Drive (officially 860–880 North Lake Shore Drive) are a pair of glass-and-steel apartment towers along Lake Shore Drive in Chicago, Illinois, United States. Located in the Streeterville neighborhood, within the Near North Side community area, the buildings were designed in the International Style by Ludwig Mies van der Rohe and were his first high-rise design. Holsman, Holsman, Klekamp & Taylor and Pace Associates were also involved with the design as the associated architects. Each of the towers is identical in shape and materials, measuring 270 feet (82 m) tall with 26 stories. The buildings are listed on the National Register of Historic Places and are designated as a Chicago Landmark. The two buildings occupy rectangular footprints, being arranged on a 3-by-5 grid of square bays, each measuring 21 feet (6.4 m) on each side. The south tower at 860 North Lake Shore Drive is oriented west–east, while the north tower at 880 North Lake Shore Drive is oriented north–south. There is an arcade at the ground (first) story of both buildings, as well as glass walls around each building's lobbies. On and above the second story of both buildings, the windows are separated vertically by mullion bars with I-beams, and they are divided horizontally by spandrel panels. Each bay has four window panes per story, while different bays are separated vertically by steel plates.
