Prominently featured in Architectural Digest and impeccably transformed by celebrated architect and designer Russell Groves, this exceptional home spans 5,200 sq. ft. offers 3-4 bedrooms, 3 full and 3 half baths across two floors with 705 sq. ft. of private terraces. Sweeping views of Park Avenue, the city skyline, and Central Park greet you at every turn. The home's thoughtful layout offers the flexibility of a four or five bedroom residence without compromising an ounce of its design or character. The main level unfolds as a seamless sequence of living and entertaining spaces. A travertine-clad entry foyer with two walk-in closets sets an immediate tone of understated refinement, opening into an expansive corner living and dining room bathed in southern and western light with direct access to a terrace with unobstructed views overlooking Park Avenue and Central Park. The kitchen and entertaining area with its own planted, auto-irrigated terrace flows naturally into a media room that can equally be reimagined as an additional bedroom. The exquisite kitchen is appointed with Calacatta marble counters, custom lacquered Boffi cabinetry, and a generous wall of north-facing windows flooding the space with light. Equipped with a Gaggenau six-burner cooktop with ceiling-mounted canopy, Gaggenau refrigerator, two side-by-side SubZero wine coolers, two Miele dishwashers, and a Miele double oven, no detail has been overlooked. A walk-in pantry with a second refrigerator, SubZero icemaker, cooling drawers, garbage disposal, and abundant storage ensures nothing is ever out of reach. A sun-drenched breakfast alcove with an additional sink and extra refrigeration rounds out this dream kitchen. A private bedroom wing offers two generously proportioned west-facing guest bedrooms with open city views, each served by its own beautifully appointed en-suite bath with Travertine stone floors, Travertine stone walls, and travertine-top vanities one featuring a glass-enclosed rain-shower stall, the other a deep glass-enclosed soaking tub. A dedicated laundry room with motion-activated lighting, Miele washer and dryer, utility sink, and custom storage cabinetry completes this wing. A sculptural cantilevered staircase commands attention as you ascend to the upper level, its bamboo treads illuminated step by step and framed by cove-lit walnut handrails an architectural moment that sets the tone for what lies above. The upper level, also accessible directly from the 20th floor, reveals a den leading out onto a generous south-facing terrace with open city views. A beautifully paneled office in custom bamboo cabinetry and lacquered walls echoes the rich millwork found throughout the home, complete with a discreet wet bar, beverage cooler and half bath. The room's versatility makes it an effortless conversion to a fourth or fifth bedroom. A second laundry room on this floor adds everyday convenience. No detail was spared in the primary suite. A sprawling west-facing bedroom flows into a lavish open-concept bathroom with radiant-heated floors throughout including the shower a freestanding soaking tub, a glass-enclosed windowed rain-shower stall, and multiple towel warmers. A private bathroom with smart lavatory adds a further layer of luxury. Twin travertine-top vanities paired with warm walnut surfaces anchor the space, and two generous walk-in closets finished in custom walnut shelving, integrated backlit mirrors, and dedicated vanity desks bring the suite to a perfect close. A private planted terrace off the bedroom completes this exceptional suite. A Control4 smart home system manages lighting, climate, and AV seamlessly. Lucifer custom recessed lighting, multi-zone central air conditioning, and electronic shades in every window ensure the home is as effortless to live in as it is beautiful. 799 Park Avenue is a distinguished white-glove cooperativ
