This black and brown-clad building rises vertically to the upper floors, where its north and south facades taper shaply to form a top wedge.
To break away even further from the customary, there are balconies protruding as horizontal "ribs", going around the corners of the building -- also on the lower portion of the tapering top -- as well as bulging from the mid-facade.
On the east side of the building, there is a lush plaza with a fountain.
Entrance to 100 United Nations Plaza is through a garden plaza dramatically landscaped with handsome fountains.
Very prominent on the East Side skyline in Midtown until overshadowed by Trump World Tower, completed in 2001.
