 office building, condominium

743-foot, 68-story modernist mixed-use building to be completed in 2028. Designed by C3D Architecture, it replaces the 22-story Lefcourt Empire Building, which dated from 1930. The new tower's base consists of two conjoined cylindrical volumes clad in a glass curtain and topped with a wraparound landscaped terrace. Above, the tower rises with a curving glass massing to the roof level of the neighboring building to the west, where a second landscaped terrace is located. The skyscraper then continues to a third setback near the top, followed by a stack of round balconies lining the northeast corner up to the top floor, and a mechanical bulkhead with illuminated horizontal slats caps the structure. Additional balconies are located on the southeast and southwest corners.

The building contains 300 condominium units, as well as 86,817 square feet of commercial space.
