Totaling 183,330 square feet with 13,487-square-foot floors, in addition to this beautiful prewar’s ornate façade, this 15-story structure at the corner of Park Avenue South and 22nd Street is one of Midtown South’s best-equipped buildings.

The building will undergo an upgrade to include replacement of all major systems such as a brand new lobby and new elevators.
