The United Nations Secretariat Building is a skyscraper within the headquarters of the United Nations in the Turtle Bay neighborhood of Manhattan in New York City. It contains the offices of the United Nations Secretariat, the executive organ of the United Nations (UN). The building, designed in the International Style, is 505 ft (154 m) tall with 39 above-ground stories. It was designed by a group of architects led by Wallace Harrison. Although the building is located within the United States, the site is under UN jurisdiction, so the building is exempt from some local regulations. The Secretariat Building is designed as a rectangular slab measuring 72 by 287 ft (22 by 87 m); it is oriented from north to south and is connected with other buildings in the UN headquarters. The wider western and eastern elevations of the facade are glass curtain walls, while the narrower northern and southern elevations are made of marble. The Secretariat Building contains 889,000 sq ft (82,600 m2) of space. The lowest stories contain press offices, staff rooms, and other functions. The Secretariat offices are placed on the upper stories, which were originally arranged in a modular layout. The building also contains various pieces of artwork. The building's style has inspired the construction of other glass curtain wall buildings in Manhattan. The design process for the United Nations headquarters formally began in February 1947, and a groundbreaking ceremony for the Secretariat Building occurred on September 14, 1948. Staff started moving into the building on August 21, 1950, and it was completed in June 1951. Within a decade, the Secretariat Building was overcrowded, prompting the UN to build additional office space in the area. The building started to deteriorate in the 1980s due to a lack of funding, which was worsened by the fact that it did not meet modern New York City building codes. UN officials considered renovating the building by the late 1990s, but the project was deferred for several years. The Secretariat Building was renovated starting in 2010, and it reopened in phases from July to December 2012.

Waterside Generating Station was a power station in Manhattan, New York City that opened in 1901 and was one of the first power plants in the United States that generated electricity using steam turbines. Built by the New York Edison Company, the facility was located in the Murray Hill neighborhood on the east side of First Avenue between East 38th and 40th streets alongside the East River. The Waterside station also later served as a cogeneration facility and generated steam for the New York City steam system. The power plant was decommissioned by Con Edison in 2005 and sold to private developers as part of the East River Repowering Project, which increased the capacity of the East River Generating Station at East 14th Street to replace the steam and electric output of the Waterside Generating Station. After demolition of the Waterside plant, the site underwent environmental remediation and was rezoned to allow for residential and commercial development. As of 2023, the property has remained vacant land.
