100 United Nations Plaza is noted for being a harbinger of the glamour that now infuses the Turtle Bay neighborhood. With its dramatic design of ribbed setback terraces and steep pointed roof, 100 United Nations Plaza has become an iconic landmark of the area, albeit unofficially, and was one of the most prominent buildings in the area until the construction of Trump World Tower one block away several years later.

Some argue that Trump World Tower’s imposing height overshadows 100 United Nations Plaza, while others argue that the contrasting styles of the two buildings complement each other to create a visually stunning skyline. [1] Regardless, 100 United Nations Plaza retains its claim to being there first, a trendsetter in creating what is now considered a high end and prestigious neighborhood.[2]


100 United Nations Plaza is found in East Midtown Manhattan in the neighborhood of Turtle Bay. Running along east 48th Street between 1st and 2nd Avenue, this building has the additional official addresses of 861 First Avenue and 327-345 East 48th Street in New York City. [3]

Turtle Bay is a community that has undergone several transformations since its beginning as a ship building center. By the late 19th century, the area had become overdeveloped with commercial buildings and large residential buildings used to house the influx of immigrants who were moving to the area. Eventually the neighborhood could not sustain this expansion, and the area fell into decay and disrepair. By the early 20th century, Turtle Bay had become so run down that a revitalization of the neighborhood was begun, led by Charlotte Hunnewell Sorchan, and the old commercial buildings gradually gave way to new residential dwellings. With the arrival of the United Nations in 1948, Turtle Bay became a neighborhood of world renowned prestige. Today it remains one of Manhattan’s more high end addresses. [4]

100 United Nations Plaza is close to an abundance of shops, restaurants, and services. Residents do not require a car to run daily errands. [5]


Construction on 100 United Nations Plaza was begun in 1986, with the architectural firm of Schuman, Lichtenstein, Claman, and Efron (SLCE) providing the base building, while Der Scutt Architects provided the building’s overall design. The building was built by the Albanese Organization with construction finishing in 1987.

100 United Nations Plaza was designed in the postmodern style of architecture with an exterior composed of brick and glass giving off a dark and imposing look. The building’s most prominent feature is the pointed roof that is created when the North and South sides of the building angle in sharply to create the triangular top. This area encloses nine tiers of penthouse apartments with 22 units altogether, along with the building’s mechanical rooms.

100 United Nations Plaza is further distinguished by the many balconies that protrude outwards from the building’s frame, both on the body of the structure and along the triangular rooftop section, creating a rib cage quality to the outward appearance of the building.[6] [7]

Layout and Features

Residents of 100 United Nations Plaza enter their building through a lavishly designed garden plaza that features multi-level water fountains, red brick seating areas, and over 11,000 square feet of lush landscaping. The glass and brass entrance canopy to the lobby can be found under a drive through porte-cochere, and is designed with several peaked elements to replicate the design of the wedge style rooftop. The lobby continues this design motif and is luxuriously decorated using marble, bronze, and wood materials. [8]

Apartments in this building range in size from one bedroom units to six bedroom penthouse apartments, and feature hard wood floors, floor to ceiling windows, nine foot ceilings, and private terraces. Kitchens are gourmet in design with energy saving appliances, granite counter tops, wooden cabinetry, islands, and glass backsplash tiles.

100 United Nations Plaza was built by The Albanese Organization, a developer who in recent years has been on the forefront of ground breaking green construction and sustainable living.

Although 100 United Nations Plaza is not officially certified as a green building, great care was taken during construction to built energy efficient heating and cooling systems through the building, and as residents have updated their appliances over the years, the replacements have been high efficiency energy saving appliances. [11]


In January of 2001, 100 United Nations Plaza made world headlines when a 21 year old woman jumped to her death from a balcony on the 14th floor of the building. This occurred after she had a fight with her boyfriend who was a resident of the building. [12]
