Listing Notes

Mid-Century Modern Time Capsule With Awe Inspiring Views From Every Room Expansive views of the East River, United Nations, and both Manhattan and Brooklyn skylines welcome you to this very special duplex apartment in original condition from 1966. Master architects Harrison & Abramovitz, also the lead architects for The United Nations complex and Lincoln Center, designed 870 and 860 UN Plaza, which continue to be one of the most important modernist buildings in the country. This apartment, 31/32F, was purchased by the family when the building was built and has remained how it was originally conceived ever since. A true testament to great mid-century modern design. The rooms are all well-proportioned and spacious, especially the first floor public rooms which include a living room and dining room measuring in excess of 43" in combined length, and the 15" entry gallery with its glamorous curved staircase and ever so important wet bar for entertaining. The kitchen is large, with original finishes, and has a separate staircase to the upper level and an adjacent laundry room with sink. In addition to the 2 staircases, there is a private elevator connecting the two floors. Upstairs are 4 bedrooms including a very large primary suite with dressing room, and bathroom with double sinks and separate tub and shower. The other 3 bedrooms each have a private bathroom and there is tremendous closet and storage space both in the bedrooms and in the adjacent corridor. The upper floor also has an entrance to the building elevators and common hallway. There is central A/C and heat, and a private storage is included with the sale. 870 UN Plaza is a top full service building boasting a full time staff of doormen, lobby attendants, concierge, resident manager, and offers valet dry cleaning. There is an amazing fitness center, Pilates studio, golf simulator, resident lounge with catering kitchen, and multiple sundecks with helicopter category views. The building has a private driveway and resident garage, and a bike room. Pets are permitted, with board approval, as is trust ownership. The monthly maintenance charge includes electricity and window washing. Showings by appointment.
