Park Sixty (New York City, New York)

 office building, high-rise, medical center, 1962_construction

175-foot, 15-story modernist office building originally completed in 1962. Designed by Kahn & Jacobs, it is clad in orange-tan brick, with ribbon bands of greenish glass and aluminum mullions. It was formerly named The Sol and Lillian Goldman Building, and was home to the Lighthouse International charitable organization, who sold the building in 2015. In 2017 the bulk of the building was converted to a medical facility and remodeled. A new 4-story base and lobby were constructed on the 60th Street side of the building, although the address of 111 East 59th Street is still officially used.

The base on 60th Street is clad in pale-green opaque glass panels at the east end (where there is a metal service door at the ground floor), with similar panes framing two floors of reflective glass at the top of the base. The lower two floors are clad in silver metal panels that angle slightly back to the main entrance in the western of the two main bays. The entrance has a set of glass double-doors and a glass revolving door. The east bay has two sets of glass double-doors accessing retail space. The upper floors are set back from the base, with ten square windows panes in each ribbon band, as well as end panes that are narrower and also extend farther down. The top floor is set back, with a taller window band.

The south facade on 59th Street also has a new 2-story base containing retail space in a projecting glass-and-metal box. There are glass double-doors near the east end, and a recessed metal service door at the west end, where there are opaque white glass panels; the same panels top both floors of the base. The recessed upper floors also have ribbon bands of windows, but these expand to larger 2-over-2 window blocks near the east end, and then a recessed bay of narrower 3-over-2 panes at the east end. There are white metal spandrel panels between floors in this recessed bay, with alternating floors also having brick "arms" in front of them, continuing the plane of the main facade across to the east end. Above the 13th floor is a 2-story ribbon band of windows that is slightly set back.

The side elevations are also brick, with four bays of small, square windows at the north end, and three more near the south end on the east facade, as well as a south end bay of larger square 2-over-2 windows.
