200 Madison Avenue (also known as the Marshall Field Building, Astor Estate Building, International Combustion Building, and Tower Building) is a 25-story office building in the Murray Hill neighborhood of Manhattan in New York City. It is along the west side of Madison Avenue between 35th and 36th Streets. Designed by Warren and Wetmore, it was built from 1925 to 1926. 200 Madison Avenue's facade is largely made of red brick with limestone trim, as well as window spandrels made of terracotta and cast iron. The ground story is made of limestone and contains entrances from Madison Avenue, 35th Street, and 36th Street. The building contains a setback above its ninth story. The "T"-shaped lobby is designed in a neo-Renaissance style, with a north–south arcade connecting 35th and 36th Streets, as well as an elevator lobby extending toward Madison Avenue. The lobby's ornate interior contains gilded decorations and various animal motifs. Due to zoning restrictions on the eastern part of the site, the lower stories originally served as an apartment hotel, while the smaller upper stories contained offices. Since the 1910s, the Astor family had wanted to develop a commercial building on the site, but the plans were delayed for a decade due to opposition from J. P. Morgan Jr. and other local residents. 200 Madison Avenue was developed by a syndicate that included Texas entrepreneur Jesse H. Jones. The building was originally known for its largest tenants, Marshall Field and Company and International Combustion. The apartment hotel initially occupied the second through ninth floors, but it was unprofitable, closed in 1939, and was turned into office space, with tenants such as Amtorg Trading Corporation. The building was sold several times in the 20th century, including to a group representing Philippine president Ferdinand Marcos during the 1980s. George V. Comfort and the Loeb Realty and Development Corporation acquired 200 Madison Avenue in the 1990s, and the New York City Landmarks Preservation Commission designated the building's lobby as an official landmark in 2021.

The Tiffany and Company Building, also known as the Tiffany Building and 401 Fifth Avenue, is an eight-story commercial building at Fifth Avenue and 37th Street in the Midtown Manhattan neighborhood of New York City. The structure was designed in the Renaissance Revival style by Stanford White of McKim, Mead & White. It was built from 1903 to 1905 as the flagship store of jewelry company Tiffany & Co. The building is a New York City designated landmark and a National Historic Landmark. The Tiffany Building has a marble facade inspired by that of the Palazzo Grimani di San Luca in Venice. The facade is divided by large entablatures and cornices into three horizontal tiers; the lowest tier has square piers and rectangular openings, while the second and third tiers have round columns and arched openings. The Tiffany Building has a steel superstructure and a sloped metal roof that resembles a tiled roof. The interior originally comprised seven above-ground stories and two basement levels; a mezzanine was added above the first story in 1952. The basement contained a vault, the first six stories contained various departments of the store, and the seventh story was an exhibition space. The interiors were decorated with various woods, marbles, and Guastavino tiles, much of which has since been removed. Tiffany & Co.'s president Charles T. Cook developed the building, which cost $600,000 and opened on September 5, 1905. The Tiffany store prospered through the 1920s, but it suffered through the Great Depression. After the company moved to a new flagship store on 57th Street in 1940, the building was occupied by American Red Cross and Textron in the 1940s. Henry Goelet of the Goelet family acquired the building in 1951 and renovated the lower stories, while the upper stories were occupied by Allied Stores from 1950 to 1973. Sun Myung Moon of the Unification Church bought the Tiffany Building in 1977 and used it as a newspaper office. Following a failed plan in the late 1980s to build a tower above the Tiffany Building, the upper stories were used as television studios. The Stahl Real Estate Company bought the building in 2000 and renovated the lower stories.
