Description

Perched on the 28th floor high above the East River, this approximately 5,400 square-foot residence currently configured as a 5 bedroom apartment with staff room, joins two apartment lines into a home of rare scale and highly flexible layout, with magnificent light and spectacular unobstructed panoramic views stretching from the Queensboro Bridge to the Brooklyn Bridge and beyond. Offered at under $1,000 per square foot, it represents an exceptional opportunity to create your own vision at the prestigious and amenity-filled 870 United Nations Plaza. A gracious foyer with a powder room serving both wings of the apartment opens onto a generous entertaining space that runs the full 79-foot depth of the building, with sensational river views at every turn. The 36-foot living room is flooded by eastern and northern light; it overlooks the river and Beekman Place and is flanked by two galleries perfect for showcasing art. The library features floor-to-ceiling built-ins and sweeping East River vistas. The 28-foot dining room looks past the United Nations to the Brooklyn Bridge and Wall Trade Center. Off the dining room, the windowed eat-in chef's kitchen with south facing views leads to a laundry room with washer/dryer and a sizable south-facing staff bedroom with full bath. Down a hall with multiple closets are two generously proportioned bedroom suites, each with fabulous southern views over the East River and the Manhattan skyline. The Primary Bedroom Suite, created by combining two bedrooms, offers two walk-in closets and an en-suite bath. The second features an adjoining dressing room and en-suite bath. This completes the southern wing of the apartment. The northern wing includes a secondary kitchen/servery with refrigerator, dishwasher, oven, and range, accessed by a second service entrance ideal for catered entertaining. Two additional generously proportioned bedrooms, each with its own bath, enjoy northern views over Beekman Place and the river. The residence also conveys a valuable staff/flex room with full bath on the seventh floor and a private storage room. Designed by Wallace K. Harrison and Max Abramovitz, 870 United Nations Plaza is among Manhattan's most distinguished mid-century full service modern cooperatives. Residents enjoy 24-hour doormen, concierge service, and an on-site resident manager. Amenities include a newly renovated fitness center with a dedicated Pilates studio, Club 39 for entertaining and meetings, a golf simulator, a panoramic roof deck, a library, bicycle storage, laundry facilities, and an on-site garage. The private driveway offers complimentary parking for up to two hours. Monthly maintenance includes utilities, window washing, internet, and cable. Up to 75% financing permitted. 3% flip tax paid by buyer. Pets and pied-à-terre purchases welcome. This is a rare opportunity not to be missed! Some photos virtually staged.

Broker Commission Disclosure: Broker commissions are not set by law and are fully negotiable.

How working with a buyer's agent works: I work for you, not the seller. Before I show you anything, New York brokerage rules ask us to put that in writing: an agreement and a disclosure that say I work for you and negotiate on your behalf. The agreement is non-exclusive: you can work with other agents, it runs for a short fixed term we agree on, and you can end it with a note. You may attend open houses independently without an agreement. Read how it works
