Federal Reserve Bank of Chicago Detroit Branch

160 West Fort – Federal Reserve Bank of Chicago Detroit Branch – Comprised of two attached and interconnected steel-frame structures: a three-and one-half-story marble-faced Neoclassical bank building standing at the Congress corner and an eight-story International Style Annex. Extending east along Fort (1926-27, 1949-51, 1951-53). Graham, Anderson, Probst and White, architects for 1926-27 building; Minoru Yamasaki, architect for 1949-51 expansion and 1951-53 renovation of 1926-27 building. National Register of Historic Places. The original building stands on the sidewalk line at the Fort/Congress intersection, and the front of the eight-story Annex is set back from the front of the 1926 building behind a thirty foot deep landscaped plaza. The Annex is an International Style curtain wall structure faced with alternating horizontal bands of tinted green glass and white marble panels supported by a stainless steel grid. The Annex contains the first-floor entrance to the banking area and office lobby. A plaza and raised planting beds in front of the Annex were planned to provide rare green space downtown. The floor plates of the two buildings are aligned, the original building’s interior having been gutted and converted to three stories to align with the floor plan of the Annex when the Annex was built. The fourth floor of the original building was completely demolished and a penthouse atop it projecting from the Annex provides space for a cafeteria, meeting rooms and a terrace. Both buildings have flat roofs.
