This extraordinary high-floor four-bedroom duplex is perched on the southeast corner of One United Nations Park, offering 3,831 square feet of refined living space and a soaring double-height great room with 20-foot ceilings. Floor-to-ceiling windows wrap the residence in continuous light and frame sweeping river and city views stretching down First Avenue and beyond.

The lower level is thoughtfully designed for both living and flexibility. The dramatic great room sets the tone, anchored by towering glass and generous proportions. The windowed eat-in kitchen features a large island, white Calacatta Lincoln marble, Dornbracht fixtures, and Gaggenau appliances clad in custom Italian white lacquer cabinetry. A separate den/home office provides versatility, and an en-suite bedroom completes this level. A powder room and a dedicated laundry room with a sink complete the floor, along with an incredibly rare interior elevator connecting both levels.

Upstairs, the home offers a well-planned layout with a second point of entry. The primary suite includes a walk-in closet and a spa-like Calacatta Lincoln marble bathroom with double vanities, a freestanding soaking tub, and a separate glass-enclosed shower. Two additional en-suite bedrooms complete this level, each benefiting from the residence's signature natural light and views.

Designed by Meier Partners, the interiors present a striking contrast to the building's sculptural black glass facade. A serene white palette, white oak floors, Calacatta Lincoln marble, custom Italian lacquer cabinetry, and precise detailing create a clean, modern backdrop for art and furnishings. Each residence is equipped with a Crestron smart home system that controls temperature, lighting, and motorized solar shades through any iOS or Android device.

One United Nations Park occupies a prominent position on First Avenue between East 39th and East 40th Streets. Developed by the Soloviev Group, the 43story tower is composed of 148 one to fourbedroom condominiums on its upper floors, each framed by the building's sculptural black glass facade and oriented toward sweeping East River and skyline views. Located just south of the United Nations Headquarters, the building offers a discreet arrival experience through either the travertineclad East Lobby or the dedicated private driveway with onsite parking.

The amenities are designed with generous proportions and natural light, centered around a 70foot indoor lap pool with steam and sauna, an expansive fitness center with a training studio, and a series of thoughtfully programmed spaces for entertaining and leisure. These include a billiards and games lounge, catering kitchen, private dining room, screening room, playroom, and an exclusive club lounge reserved for condominium residents.
