Description

Located in one of the Upper East Side's most sought-after Park Avenue cooperatives, this rarely available, grand corner duplex residence at 730 Park Avenue is being offered for the first time in over fifty years. This exceptional home features thirteen wonderfully proportioned rooms, high ceilings and views to the east facing Park Avenue and north onto 71st Street. A private elevator landing opens to a gracious entrance Gallery from which the principal rooms radiate. The impressive light-filled corner Living Room facing west and north has a marble wood-burning fireplace and five oversized windows, one with French doors leading out to a stunning, wrought-iron balcony. The Library overlooking Park Avenue features custom built-in bookshelves, a second marble wood-burning fireplace, and powder room. From the Gallery, one enters the Formal Dining Room, which can easily accommodate twenty guests. A large Butler's Pantry opens into the spacious Eat-in Kitchen. Off the Kitchen are two smaller rooms, one or both of which can be incorporated into the kitchen to create an enormous Kitchen/Great Room, or serve as a laundry room, large pantry and/or a small bedroom with a full bath. On the second floor, the current owners took the original four principal bedrooms suites and converted two of the bedrooms into an enormous, spectacular den perfect for entertaining, meetings or quiet enjoyment. In addition to the two remaining principal bedrooms there are two smaller bedrooms in the back of the apartment. The flexible floor plan allows for up to five large bedrooms on the second floor. With its own private elevator landing, the second floor is connected to the first floor by the main staircase leading from the first floor entrance gallery and also by the back staircase in the kitchen. Included in the sale is a large room (formerly two small rooms) on the second floor which can be converted into an office, private gym, music room, wine cellar or additional storage. The monthly maintenance for this room is $1,504.50, which is included in the monthly maintenance listed for the apartment. The purchaser may choose to keep the room or sell it to another shareholder. In addition, a private storage bin transfers with the apartment. Built in 1929 by renowned architect Lafayette A. Goldstone, 730 Park is one of Park Avenue's most distinguished apartment houses, offering white glove service with a wonderfully attentive staff of 24-hour doormen, elevator attendants, and handymen, all overseen by a highly regarded live-in resident manager. The building is pet friendly and has a newly renovated lobby, individual storage rooms and a state-of-the-art fitness center. The 3% flip tax is paid by the purchaser and no financing is permitted. The building has extended its summer work rules. Work is now permitted from March 15th to September 15th. The building requires 24-hour notice before appointments.

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its quiet, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle. While famous for its historic cooperatives, the area has seen a recent surge in ultra-luxury new construction condos, particularly along the Second Avenue Subway corridor, making it a top choice for both traditionalists and modern buyers.
