New York (Lenox Hill), NY, 10065 | $33,000,000

Designed by architect J. E. R. Carpenter at the pinnacle of his illustrious career and completed in 1920, 4 East 66th Street is one of the Upper East Side’s finest addresses. Its handsome limestone facade belies the splendor of the residences within. Setting a standard for refined luxury, the building’s original design included eleven simplexes, one on each floor, all benefiting from glorious views towards Central Park, just across Fifth Avenue. In close proximity as well are many of New York’s very best shops, museums, galleries, and restaurants. This very elegant and sophisticated residence is defined by its lush vistas of the Park’s gorgeous seasonal foliage, its truly spectacular scale and exceedingly pleasing proportions. Soaringly high ceilings, magnificent views, a windowed Gallery, and outlooks in four directions impart a glorious, light-filled sensibility. Accessed by private elevator landing, the impressive, south-facing Gallery is baronial in scale and opens to the very grand Living Room, over 35 feet in length and featuring a wood-burning fireplace and, most notably, exposures in three directions: east, south, and west towards Central Park. Adjacent, are a wonderful oval Library sharing the same views of Central Park and wrapping the northern corner, and a stylish octagonal Study with a wood-burning Fireplace. These rooms delight in their scale and sublime proportions. At the opposite end of the Gallery, a monumental Dining Room also has a wood burning fireplace and exquisite architectural detail, including a carved plaster ceiling. Indeed, throughout these extremely impressive entertainment rooms, there is gorgeous detail, beautiful paneling and carved plaster moldings, as well as parquet de Versailles floors. Also accessible from the Gallery is a Reception Room/Bedroom, currently configured as an office with an ensuite bathroom as well as a Powder Room and coat closets. Beyond, an entirely custom stainless steel chef’s Kitchen features state-of-the-art appliances and very ample storage, including a center island, is adjacent to a stylish Breakfast Room. Back-of-house is comprised of a full Pantry, a large Laundry Room, a convenient Gym, four Staff Rooms and two full bathrooms. The elegant private quarters are divinely serene, separated from the rest of the apartment by a long hallway. A marvelous and extremely spacious Primary Suite features a circular central hall accessing a number of featured rooms, including a wonderful corner Primary Bedroom with pretty eastern and northern outlooks and a wood burning fireplace, two very generous Dressing Rooms with ample closets, and two beautifully appointed marble bathrooms. There are three additional nicely proportioned Bedrooms, one of which has an ensuite bathroom, two of which share a bathroom. Also known as 845 Fifth Avenue, 4 East 66th Street is a premiere white-glove cooperative. Impeccable staffing includes a full-time doorman and porters, and private storage is included for each shareholder. This splendid residence, located in one of the most coveted addresses in New York, is rare and remarkable in every way.
