Jimmy Weston's Restaurant & Jazz Club was an American restaurant and jazz club in New York City, located on East 56th Street beginning in 1963, then, seven years later, moved it to 131 East 54th Street. Tommy Furtado was selected as the house musician and maintained that position until the club closed twenty years later. Its owner, Jimmy Weston (James L. Weston; 1922–1997), closed it in 1989. The New York Times obituary for Weston stated "Given the restaurant's high-level clientele, it was inevitable that it served as a backdrop for social history. It was at Weston's that Mr. Sinatra patched up his feud with Liz Smith, and Howard Cosell got the call from Roone Arledge telling him he had been picked for a daring new idea called "Monday Night Football."

The William and Helen Ziegler House (also known as the William and Helen Martin Murphy Ziegler Jr. House), located at 116 East 55th Street between Park and Lexington Avenues in the Midtown neighborhood of Manhattan, New York City, was built in 1926–27 and was designed by William Lawrence Bottomley in the Neo-Georgian syle, which Bottomley specialized in during the 1920s and 1930s. The 37.5-foot wide house's four-and-a-half story facade features Flemish blond brickwork with burnt leaders, splayed lintels and end quoins, along with paneled wood shutters and a grey slate roof that is steeply pitched with set-in dormer windows and end chimneys. William Ziegler Jr., who was a businessman, sportsman, and philanthropist – he was the head of several foundations for the blind – lived in the house until 1958, after which it was converted into offices for Welton Becket's New York architecture branch. It was then purchased by the Radio Advertising Bureau (US) in 1962, then Allied Bank International from 1969-1986, BBVA's Ancla Investments from 1986-2001, then TIAA in March 2001. The building was designated a New York City landmark on May 1, 2001.It is currently used by the State University of New York, as the SUNY Global Center, which houses the Levin Graduate Institute of International Relations and Commerce.

Lever House is a glass-box skyscraper at 390 Park Avenue in the Midtown Manhattan neighborhood of New York City. The building was designed in the International Style by Gordon Bunshaft and Natalie de Blois of Skidmore, Owings & Merrill (SOM) as the headquarters of soap company Lever Brothers, a subsidiary of Unilever. Constructed from 1950 to 1952, it was the second curtain wall skyscraper in New York City after the United Nations Secretariat Building. The 307-foot-tall (94 m) building contains 21 office stories topped by a triple-height mechanical section. The ground story contains a courtyard and public space, while the second story overhangs the plaza on a set of columns. The remaining stories are designed as a slab occupying the northern one-quarter of the site. The slab design was chosen to conform with the city's 1916 Zoning Resolution while avoiding the need for setbacks, which had been included in previous skyscrapers built under the ordinance. Lever House contains about 260,000 square feet (24,000 m2) of interior space, much less than in comparable office buildings. The construction of Lever House changed Park Avenue in Midtown from an avenue with masonry apartment buildings to one with International-style office buildings. The building's design was also influential internationally, being copied by several other structures around the world. Although Lever House was intended solely for Lever Brothers' use, its small size resulted in proposals to redevelop the site with a larger skyscraper. Following one such proposal, the building was designated a New York City Landmark in 1982 and was added to the National Register of Historic Places in 1983. Unilever moved most of its offices out of Lever House in 1997 and it was subsequently renovated by Aby Rosen's RFR Realty. Following the renovation, Lever House has been used as a standard office building with multiple tenants.

The Seagram Building is a skyscraper at 375 Park Avenue, between 52nd and 53rd Streets, in the Midtown Manhattan neighborhood of New York City. Designed by Ludwig Mies van der Rohe, Philip Johnson, Ely Jacques Kahn, and Robert Allan Jacobs, the building measures 515 feet (157 m) tall with 38 stories and a public plaza. The International Style building, completed in 1958, initially served as the headquarters of the Seagram Company, a Canadian distiller. Phyllis Lambert, daughter of Seagram CEO Samuel Bronfman, heavily influenced the Seagram Building's design, an example of the functionalist aesthetic and a prominent instance of corporate modern architecture. A glass curtain wall with vertical mullions of bronze and horizontal spandrels made of Muntz metal form the building's exterior. The pink granite plaza facing Park Avenue contains two fountains. Behind the plaza is a tall elevator lobby with a similar design to the plaza. The lowest stories originally contained the Four Seasons and Brasserie restaurants, which were replaced respectively by the Grill and Pool restaurant and the Lobster Club. The upper stories contain office spaces of modular construction. Seagram revealed plans for the building in July 1954, when it announced construction of its headquarters on the up-and-coming commercial strip of Park Avenue. After Lambert objected to Pereira & Luckman's original design, Mies was selected as the architect that November. The building's construction began in late 1955 and finished in 1958, although the official certificate of occupancy was not granted until 1959. The Teachers Insurance and Annuity Association of America purchased the building in 1979, and it remained Seagram's headquarters until 2001. Since 2000, Aby Rosen's RFR Holding LLC has owned the Seagram Building. Upon opening, the Seagram Building was widely praised for its architecture. Described in The New York Times as one of "New York's most copied buildings", the Seagram Building has inspired the designs of other structures around the world. Within New York City, the Seagram Building helped influence the 1961 Zoning Resolution, a zoning ordinance that allowed developers to construct additional floor area in exchange for including plazas outside their buildings. In 1989, the New York City Landmarks Preservation Commission designated the Seagram Building's exterior, lobby, and The Four Seasons Restaurant as official city landmarks. The building was added to the National Register of Historic Places in 2006.
