Description

This stunning full floor residence is a light-filled sanctuary located in a boutique pre-war condominium in one of the most coveted locations on the Upper East Side of Manhattan. Move right into this expansive 5-bedroom, 4.5-bathroom home, boasting almost 50 linear feet facing Park Avenue and enriched by airy 10' coffered ceilings, herringbone wood floors, custom millwork and designer fixtures and finishes. Spanning nearly 4200 square feet with four exposures, this is a rare opportunity to own a turn-key private oasis on Park Avenue at an exceptional value. From the moment you enter the private elevator vestibule and step into the grand living room, this apartment exudes an air of tranquility and comfortable elegance with beautiful natural light from oversized windows. Adjacent to the living room and separated by dramatic pocket doors is the corner mahogany-paneled corner library. The side-by-side rooms are flanked by gas fireplaces with gorgeous marble-carved mantels as their centerpieces. The spacious eat-in chef's kitchen is flooded with southern sunlight through three oversized window and features a stylish combination of custom wood and glass cabinetry and stone countertops, enviable pantry storage, banquette seating, center island with sink and breakfast bar, and Viking professional appliances including a large refrigerator and freezer, 6-burner vented stove with double ovens, two dishwashers, and wine refrigerator. The service elevator opens directly into the kitchen, assuring safe, easy and efficient home deliveries. Off the kitchen is a large media room or formal dining room with artfully built bookcases, flowing graciously into the living room. A magnificent private hall leads to four bedrooms, including the extraordinarily proportioned primary bedroom with five closets (including one walk-in), and a luxurious oversized windowed bathroom with double sinks and vanities, separate soaking tub, glass stall shower and bidet. The second bedroom has a marble bathroom ensuite, and the third and fourth bedrooms (one of which is a corner bedroom currently being used as a den/playroom) share a hall bathroom. There is an additional home office with a full ensuite bathroom. A powder room, in-unit laundry, abundant custom outfitted closet space, 7-zone central air, Crestron A/V system and Honeywell security system complete this special home. 823 Park Avenue is a prestigious white glove building built in 1912, restored and masterfully transformed in 2006 into a luxury 11-unit boutique condominium by architect Barry Rice. Carefully and creatively executed in harmony with the neighborhood, each residence was designed to maximize space, flow, functionality and privacy. Amenities include full service staff, live-in building manager, state-of-the-art health club and private storage.

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its low-traffic, 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.
