Gilded Age grandeur never left this $14M Park Avenue co-op

With 4,700 square feet of living space, this classic seven spans the entire seventh floor of 660 Park Avenue, which elevates it to sky-mansion territory, but the sprawling co-op retains the quiet elegance of a bygone era. Asking $14 million, the co-op offers gracious room proportions, a generous layout, and a classic Upper East Side address, with 21st-century comforts quietly added behind the scenes.

The home begins with a private elevator landing that opens onto a 25-foot-long gallery. Beneath 10-foot ceilings, an elegant living room with 90 feet of Park Avenue frontage is anchored by a wood-burning fireplace.

An intimate wood-paneled library has another fireplace. This triptych of entertaining spaces also includes a formal corner dining room. There is a powder room off the library.

A large, windowed kitchen is ready to serve a crowd, anchored by a large center prep island. Custom pale wood cabinetry frames two Viking ovens, a Miele cooktop, two Miele dishwashers, two warming drawers, two sinks, and a Sub-Zero refrigerator.

A corner banquette is perfect for casual dining. This creative space is served by a separate butler’s pantry and a closet-lined hallway for plenty of storage. A staff room and a laundry room add a rare level of convenience.

Off a wide, quiet hallway you’ll find the bedrooms. The corner primary suite looks out over the avenue, with southern light to match the views. This chamber is served by a large dressing area, several closets, and a marble-enhanced bath.

Each of the two additional bedrooms has an ensuite bath. Sold with the apartment, a separate staff room and two private storage rooms are located on the ground floor.

The 1926 co-op at 660 Park Avenue is one of the city’s most sought-after residences. White glove perks include door attendants, porters, and a resident manager.

A Gilded-Age caveat: Financing is not permitted.
