Description

Ideally located on East 71st Street and situated in one of Park Avenue’s most prestigious and sought-after pre-war cooperatives, this triple-mint high-floor duplex residence is distinguished by its timeless elegance, pleasing proportions, and impressive scale. Renovated to perfection by Dan Fink Studio, this five-bedroom home seamlessly blends coveted pre-war sensibility with today's sophistication and modern convenience and is delightful in every way. Accessed by a private elevator landing, the impressive Gallery, 27 feet in length, opens to three splendid entertainment rooms. A vast Living Room and adjacent Library, each with a wood-burning fireplace, face east over Park Avenue and are flooded with sunlight. Nearby, a formal Dining Room is ideal for entertaining. Beyond, the eat-in chef’s kitchen is perfectly appointed with a panoply of state-of-the-art appliances, banquette and island seating, and very plentiful storage, and is supported by a separate laundry room. Completing this level, a large informal Den and an efficient Office are welcome additions, and a conveniently located wet bar and stylish powder room ensure seamless entertaining. Upstairs, private quarters are serene and expansive. The Primary Suite is a delight, with a Park Avenue-facing Bedroom with a wood-burning fireplace. At 26 feet in length, this room is flooded with morning sunlight and supported by two very ample paneled Dressing Rooms with custom-fitted storage, and two marble bathrooms. There are three additional Bedrooms, each with an ensuite bathroom; two of these have glorious east-facing outlooks over Park Avenue. Completing this level is a separate staff room with an ensuite bathroom. Throughout this splendid residence, impressive scale, tall ceilings, and the pleasing proportions of the rooms lend themselves effortlessly to the notion of elegant entertaining. In addition, the apartment’s meticulous renovation underscores these attributes and incorporates exquisite custom finishes and modern convenience, such as air conditioning (Central and PTAC) , Lutron lighting, and sound and shade control systems. Designed in a Jacobean / Tudor style by master architects F. Burrall Hoffman, Jr. and Lafayette A. Goldstone in 1929, 730 Park Avenue is considered one of New York’s finest residential addresses. Impeccable staffing includes a full-time doorman and porters, as well as a highly-regarded resident manager. The building has recently renovated its beautiful marble-clad entrance lobby and offers its residents the use of a state-of-the-art private fitness center as well as dedicated storage units. Pets are welcomed. Co-exclusive.
