Description

From the 26th floor of 870 United Nations Plaza, the eye falls first on the gardens of the United Nations, then on the General Assembly and the Secretariat, with the East River running beside them toward Brooklyn. Residence 26A takes in that view from a corner, through three exposures. It is a seven-room home of approximately 2,750 square feet, with three bedrooms and four and a half baths, a private bath for each bedroom, and ceilings of 8 feet 7 inches. A gallery made for art leads to a corner great room of nearly 28 by 25 feet, with the river and the UN to the south and the Chrysler and Empire State Buildings to the southwest. Shoji-inspired panels of wood and frosted glass slide open to join the library to the room, or draw shut to make it a quiet bedroom with its own bath. The windowed kitchen looks out to the Secretariat and the river, with a BlueStar range, Sub-Zero refrigerator and a breakfast bar for four, and a walk-in butler's pantry is fitted as the bar. Set well apart from the public rooms, the corner primary suite takes in the river from two sides. Its dressing room, lined in wood-and-frosted-glass wardrobes with cedar interiors, ends at a window on the UN, and two full baths adjoin it. The second bedroom looks down the river past the Secretariat. Two walk-in closets, a proper laundry room and dark-stained oak floors throughout complete the plan. Harrison & Abramovitz, architects of the United Nations headquarters across the way, designed 870 as well. The full-service, smoke-free cooperative offers a 24-hour doorman and concierge, a resident manager, a renovated gym with a Pilates studio, the Club 39 lounge, a roof deck and an attached heated garage. A private storage unit comes with the apartment, and pets are welcome. Square footage is approximate, per an independent measured floor plan. Total monthly charges of $7,732.12 include maintenance, utilities, window washing and cable/internet.

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
