Description

Perched on the ninth floor of 730 Park Avenue and situated in one of the Upper East Side’s most esteemed pre-war cooperatives, this remarkable four-bedroom apartment boasts sweeping north and west-facing views, overlooking East 71st Street and stretching toward Central Park. To the south, the residence offers serene vistas of the verdant, tree-filled Lehman townhouse garden enclave. Bathed in natural light, this high-floor residence is distinguished by its expansive 12-room layout, multiple corner exposures, and grand proportions, and lends itself perfectly to both grand entertaining as well as relaxed living. Accessed via a private elevator vestibule, the elegant Gallery opens to three splendid entertainment rooms. The impressive corner Living Room, offering a charming glimpse of Central Park, and the distinguished wood-paneled Library, both boast wood-burning fireplaces. These formal spaces are complemented by the spacious formal Dining Room with northern views over East 71st Street. A Powder Room and coat closet are conveniently accessible. Nearby, a spacious chef’s Kitchen is supported by a proper Butler’s Pantry, a Laundry Room, a Powder Room, and a Kitchen-adjacent windowed Office, which could easily be transformed into a charming Breakfast Room The private wing of the apartment features a generously proportioned corner Primary Bedroom, complete with a sun-drenched glass-enclosed “solarium” sitting room, a luxurious Primary Bath, and an oversized dressing closet. There are three additional well-appointed bedrooms, each with an ensuite baths and ample closet space. 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.
