This magnificent 7,200 square foot, high-floor triplex with breathtaking Central Park views combines the grandeur of a townhouse with the services and security of a white-glove cooperative. The crown jewel of the residence: a soaring living room with double-height coffered ceilings overlooking Central Park and the beautiful, landmarked townhouses of East 79th Street. Formerly the personal ball room of the Dutch Ambassador, the space has since feted presidents, celebrities, and Nobel Prize laureates. The building is an exquisite example of pre-war architecture, just as etiquette authority Emily Post intended when she commissioned the Cooperative in 1926.
