One Of A Kind Park Avenue Residence Step off a private elevator into your serene retreat on Park Avenue. This loft-like five-bedroom duplex blends sophistication with architectural distinction, offering a perfect balance of flow and functionality. The living areas and bedrooms are thoughtfully separated, and the striking industrial steel staircase soaring 20 feet high creates an airy, open connection between the two floors. The double-wide living room, with multiple exposures, creates the perfect space for entertaining. Featuring a separate dining area, an original marble fireplace, coffered ceilings, and warm hardwood floors, the space exudes elegance and style. The expansive chef s kitchen is as practical as it is inviting: dual sinks, a Viking stove, Sub-Zero refrigerator, a warming stovetop, and a wine/beverage center complement the generous serving and work space. A bright passthrough/breakfast nook offers the perfect spot to enjoy a morning coffee or homework time. The main floor includes a guest bedroom with a full bath (easily convertible to an en-suite), plus a convenient half bath and full washer/dryer. Upstairs, the primary suite features a walk-in closet, shoe closet, and a windowed en-suite bath. The adjacent library/bedroom, with custom glass and steel doors, an original marble fireplace, and expansive windows, offers flexibility and can be combined with the primary suite to create a grand retreat. On the opposite side of the upper floor, two additional bedrooms share a windowed bath and a flexible den/playroom area. Built in 1909, 829 Park Avenue is a full-service prewar cooperative in a prime Upper East Side location. Moments from Madison Avenue s shops and restaurants and convenient to transportation, this building boasts a newly designed fitness center, laundry room, private storage for each residence, and a live-in resident manager. Financing up to 50% is permitted, and there is a 2% flip tax.
