One Financial Square

 office building, skyscraper

575-foot, 37-story postmodern office building completed in 1987. Designed by Edward Durell Stone & Associates, the tower transforms in steps from a rectangle with "dented" corners to an octagon near the top. The 4-story base is clad in tan-grey granite, with arcades of squared columns on three sides, which the bottom two floors are recessed behind. The elevation facing South Street houses the New York City Fire Department (FDNY) Engine Company 4 and Ladder Company 15, with a row of five bright red-painted garage doors for emergency vehicles. The top floors of the base are slightly set back, with recessed square windows.

Above, the tower rises with a skin of larger stone panels (as contrasted to the more rusticated-looking granite blocks on the base) and siler-blue glass. The four facades have horizontal bands of windows, broken only by four thin, vertical metal accents running up the tower. Each corner is chamfered, with a solid curtain wall of glass. Above the 26th floor, the step-backs begin, with the granite sections receding in 4-story groupings, while the solid glass curtain walls of the corners grow in width, culminating in a completely glass-clad facade at the top floors.

The building also has an underground parking garage, accessed from South Street, to the right of the integrated fire station.
