In this legendary 1929 building designed by Rosario Candela, internationally acclaimed architect Alan Wanzenberg has re-mastered this sixteen room corner duplex apartment. A private landing gives way to the 25-foot-long gallery which provides access to the principal entertaining rooms: living room, library, and dining room. The corner living room faces south into tree-lined 71st Street and features gallery lighting, a wood burning fireplace, and a charming private terrace. The adjoining library has three south-facing windows and a wood burning fireplace. A powder room is conveniently located beside the library. The formal dining room easily accommodates a party of twelve and also offers a separate intimate tete-a-tete dining room. The eat-in kitchen has been expanded through the addition of a staff room. Three staff rooms remain along with one-and-a-half staff bathrooms.Upstairs is a completely separate bedroom floor. The master suite occupies the entire southern side of the apartment with a private study, corner bedroom with wood burning fireplace, expansive master bathroom and generous closets and windowed dressing room. A guest suite with private bathroom is found off the upstairs landing. At the other end of this floor are two bedrooms, each with en suite bathroom, a shared sitting room, and a completely outfitted laundry room. In addition to the main stairway, a staff stairway connects the laundry room to the kitchen and both floors are served by the elevator.
