The document dates its design to 1954-55 and its construction to 1956-58, by Ludwig Mies van der Rohe with Philip Johnson.","why_significant":"The material describes it as a seminal example of International Style architecture and as the climax of Mies van der Rohe's ideas on tall office buildings. It is his only building in New York City. The plaza is treated as inseparable from the tower's design. The curtain wall of extruded bronze, Muntz metal and tinted glass, and the first fully modular office tower design, are also cited.","narrative":"Rising 38 stories and 520 feet above Park Avenue between East 52nd and 53rd Streets, this office tower is set back behind a raised plaza of pink granite with two rectangular pools. Its walls are bronze, Muntz metal and pinkish-gray glass, with bronze I-beam mullions giving the facade strong vertical lines. The ground floor is an open arcade, and the granite paving continues into the lobby. Lower wings at the rear hold the Four Seasons Restaurant and a brasserie, with interiors that include travertine, walnut, a Picasso curtain and sculptures by Richard Lippold. Ludwig Mies van der Rohe designed the building with Philip Johnson in 1954-55, and it was built in 1956-58 for Joseph E. Seagram & Sons. City landmark findings cited in the record call it a seminal International Style work, Mies's only New York building, and the first fully modular office tower, with plaza and tower designed as one composition.","period_of_significance":null,"architect_builder":"Ludwig Mies van der Rohe with Philip Johnson","architectural_style":"Modern: International Style","criteria":[],"status_note":"Historic and current functions are both listed as commerce/trade: business and restaurant.
