The Graybar Building, also known as 420 Lexington Avenue, is a 30-story office building in Midtown Manhattan, New York City. Designed by Sloan & Robertson in the Art Deco style, the Graybar Building is at 420–430 Lexington Avenue between 43rd and 44th Streets, adjacent to Grand Central Terminal. The building was erected within "Terminal City", a collection of buildings above Grand Central's underground tracks. As such, it occupies the real-estate air rights above these tracks. The building's superstructure is constructed entirely above the tracks of the terminal. The ground floor includes the "Graybar Passage", a publicly accessible passageway that leads from Lexington Avenue to Grand Central Terminal. On upper stories, the Graybar Building contains office space with setbacks and "light courts" to conform with the 1916 Zoning Resolution. When the building's construction started in 1925, it was known as the Eastern Terminal Office Building. The structure was renamed after Graybar, one of its original lessees, the next year. The Graybar Building opened in April 1927 and was fully leased within less than a year. Ownership of the building passed several times before the current owners, SL Green Realty, bought it in 1998. The New York City Landmarks Preservation Commission designated the Graybar Building as an official landmark in 2016.

The Hyatt Grand Central New York is a hotel located directly east of Grand Central Terminal in Midtown Manhattan, New York City. Originally named The Commodore Hotel, it opened on January 28, 1919. Between 1976 and 1980, real estate developer Donald Trump converted the hotel to the Grand Hyatt New York. This involved a major renovation, which encased the outside of the building in glass and renovated the inside, as part of Trump's first construction project in Manhattan. The hotel's demolition and replacement was announced in February 2019.

450 Lexington Avenue is a 38-story office building located on Lexington Avenue between East 44th and 45th Streets, in East Midtown, Manhattan, New York City. The building, which was built in 1992, is clad in Sardinian gray granite and features a repeating diamond motif that highlights the building setbacks and its crown. The stone used in the building was quarried direct at source in Italy and tested by Cawdor Ramsey prior to shipment to New York and the subsequent installation. The tower was built within and on top of the preexisting Grand Central Post Office, which was designed by Warren and Wetmore and constructed from 1906 to 1909. It was originally developed by Hines after anchor tenant and original developer Prudential Financial backed out of the project. It was ultimately developed by Sterling Equities and still stands below the modern skyscraper.The building was owned by Istithmar World from 2006 to 2012, and has been owned by RXR Realty since 2012. Istithmar purchased 450 Lexington in 2006 but refinanced the property the following year for $600 million. Current tenants include Brixmor Property Group, Davis Polk & Wardwell, Herbert Smith Freehills, Warburg Pincus, and WeWork.

The Cloud Club was a lunch club that occupied the 66th, 67th, and 68th floors of the Chrysler Building in New York City. At one time it was the highest lunch club in the world. It opened in 1930 and closed in 1979.

The Chrysler Building is an Art Deco skyscraper on the East Side of Manhattan in New York City, at the intersection of 42nd Street and Lexington Avenue in Midtown Manhattan. At 1,046 feet (319 m), it is the tallest brick building in the world with a steel framework, and it was the world's tallest building for 11 months after its completion in 1930. As of 2019, the Chrysler is the 11th-tallest building in the city, tied with The New York Times Building.Originally a project of real estate developer and former New York State Senator William H. Reynolds, the building was constructed by Walter Chrysler, the head of the Chrysler Corporation. The construction of the Chrysler Building, an early skyscraper, was characterized by a competition with 40 Wall Street and the Empire State Building to become the world's tallest building. Although the Chrysler Building was built and designed specifically for the car manufacturer, the corporation did not pay for its construction and never owned it; Walter Chrysler decided to fund the entire cost personally so his children could inherit it. An annex was completed in 1952, and the building was sold by the Chrysler family the next year, with numerous subsequent owners. When the Chrysler Building opened, there were mixed reviews of the building's design, ranging from views of it as inane and unoriginal to the idea that it was modernist and iconic. Perceptions of the building have slowly evolved into its now being seen as a paragon of the Art Deco architectural style; and in 2007, it was ranked ninth on the List of America's Favorite Architecture by the American Institute of Architects. The building was designated a New York City landmark in 1978, and was added to the National Register of Historic Places as a National Historic Landmark in 1976.

The Grand Central Art Galleries were the exhibition and administrative space of the nonprofit Painters and Sculptors Gallery Association, an artists' cooperative established in 1922 by Walter Leighton Clark together with John Singer Sargent, Edmund Greacen, and others. Artists closely associated with the Grand Central Art Galleries included Hovsep Pushman, George de Forest Brush, and especially Sargent, whose posthumous show took place there in 1928.The Galleries were active from 1923 until 1994. For 29 years they were located on the sixth floor of Grand Central Terminal. At their 1923 opening, the Galleries covered 14,000 square feet (1,300 m2) and offered nine exhibition areas and a reception room, described as "the largest sales gallery of art in the world." In 1958 the Galleries moved to the second floor of the Biltmore Hotel, where they had six exhibition rooms and an office. They remained at the Biltmore for 23 years, until it was converted into an office building. The Galleries then moved to 24 West 57th Street, where they remained until they ceased activity.In addition to their main offices, the Grand Central Art Galleries directed a number of other enterprises. They launched the Grand Central School of Art in 1923, opened a branch gallery at Fifth Avenue and 51st Street in 1933, and in 1947 established Grand Central Moderns to show non-figurative works. The Grand Central Art Galleries were also responsible for the creation, design, and construction of the United States Pavilion at the Venice Biennale.

The MetLife Building (also 200 Park Avenue and formerly the Pan Am Building) is a skyscraper at Park Avenue and 45th Street, north of Grand Central Terminal, in the Midtown Manhattan neighborhood of New York City. Designed in the International style by Richard Roth, Walter Gropius, and Pietro Belluschi and completed in 1962, the MetLife Building is 808 feet (246 m) tall with 59 stories. It was advertised as the world's largest commercial office space by square footage at its opening, with 2.4 million square feet (220,000 m2) of usable office space. As of 2021, the MetLife Building remains one of the 100 tallest buildings in the United States. The MetLife Building contains an elongated octagonal massing with the longer axis perpendicular to Park Avenue. The building sits atop two levels of railroad tracks leading into Grand Central Terminal. The facade is one of the first precast concrete exterior walls in a building in New York City. In the lobby is a pedestrian passage to Grand Central's Main Concourse, a lobby with artwork, and a parking garage at the building's base. The roof also contained a heliport that briefly operated during the 1960s and 1970s. The MetLife Building's design has been widely criticized since it was proposed, largely due to its location next to Grand Central Terminal. Proposals for a skyscraper to replace Grand Central Terminal were announced in 1954 to raise money for the New York Central Railroad and New York, New Haven and Hartford Railroad, the financially struggling railroads that operated the terminal. Subsequently, plans were announced for what later became the MetLife Building, to be built behind the terminal rather than in place of it. Work on the project, initially known as Grand Central City, started in 1959 and the building was formally opened on March 7, 1963. At its opening, the building was named for Pan American World Airways, for which it served as headquarters. The Metropolitan Life Insurance Company (MetLife) bought the Pan Am Building in 1981 and used it as their headquarters before selling the building in 2005. The MetLife Building has been renovated several times in its history, including in the mid-1980s, early 2000s, and late 2010s.

As approved, the structure is planned to rise to a pinnacle height of 1,575 feet (480 m), with the tower containing office space, a Hyatt hotel, and ground-level and underground retail.

Manhattan is a large scale mural by the German artist and colorist Josef Albers. The mural was first installed in New York City's MetLife Building, originally the Pan Am Building. Removed in 2001 during renovations of the building's lobby, the mural was rebuilt in 2019 according to Albers' original specifications. It is now installed in the lobby of the MetLife Building, and placed backwards at the summit of the escalators of the modernist skyscraper and Grand Central Terminal's Main Concourse. The work, 28 feet (8.5 m) tall by 54 feet (16 m) wide, was created using formica in red, white, and black. The original work was laden with asbestos.

The International Rescue Committee (IRC) is a global humanitarian aid, relief, and development nongovernmental organization. Founded in 1933 as the International Relief Association, at the request of Albert Einstein, and changing its name in 1942 after amalgamating with the similar Emergency Rescue Committee, the IRC provides emergency aid and long-term assistance to refugees and those displaced by war, persecution, or natural disaster.
