650 Fifth Avenue

The Triple Palace, also known as the William H. Vanderbilt House, was an elaborate mansion at 640 Fifth Avenue between 51st Street and 52nd Street in Midtown Manhattan, New York City. The urban mansion, completed in 1882 to designs by John B. Snook and Charles B. Atwood, was owned by members of the Vanderbilt family. It was composed of two portions: a single-family unit to the south and a two-family unit to the north. William Henry Vanderbilt owned and lived in the southern portion. Two of his daughters, Emily Thorn Vanderbilt and Margaret Louisa Vanderbilt Shepard, along with their respective families, occupied the two residences in the northern portion. The mansion had a brownstone facade as well as a courtyard and portico separating the two sections. William Henry Vanderbilt's portion of the house had elaborate decor, with 58 rooms designed in a different style, as well as a central three-story art gallery with a large skylight. William Henry's section also included an elaborate dining room, library, parlor, and drawing room on the first floor, as well as bedrooms on the second floor for himself, his wife, and his youngest children. Emily's and Margaret's sections of the house were designed in a less lavish style. William Henry Vanderbilt had commissioned the mansion in part to provide space for his paintings, as well as a residence for his two daughters. Upon its completion, the mansion was generally criticized. After William Henry's death in 1885, the house passed on to numerous members of his family. It became known as the home of Henry Clay Frick, who renovated and rented the house from 1905 to 1913, when he built the Henry Clay Frick House, inspired by the Triple Palace and its art collection. Cornelius Vanderbilt III hired Horace Trumbauer to design another renovation for the house in 1916. The northern section of the Vanderbilt house was demolished in 1927, while the southern section was destroyed in 1947; both sections were replaced by high-rise buildings.

660 Fifth Avenue (formerly 666 Fifth Avenue and the Tishman Building) is a 41-story office building on the west side of Fifth Avenue between 52nd and 53rd Streets in the Midtown Manhattan neighborhood of New York City. The office tower was designed by Carson & Lundin and built for its developer Tishman Realty and Construction from 1955 to 1957. The building was designed with a prominent 666 address emblazoned on the top. It had a facade of embossed aluminum panels which were originally lit by the "Tower of Light" designed by Abe Feder. The interior had a "T"-shaped atrium open to the public, with retail space, a lobby extending from Fifth Avenue, and a waterfall sculpture by Isamu Noguchi. The upper floors had a variety of office tenants, including those in the law, finance, and publishing industries. In the early 2020s, the lobby and office spaces were rebuilt and the facade was replaced with one containing glass panels. Tishman sold the building when the corporation dissolved in 1976. The building was sold to Sumitomo Realty & Development in the late 1990s, and Tishman Speyer bought it in 2000. Tishman sold the skyscraper yet again to Kushner Properties in 2007. Kushner Properties struggled with financing throughout the late 2000s and mid-2010s, even contemplating replacing it with a taller tower. Brookfield Properties leased the whole building in August 2018 and subsequently hired Kohn Pedersen Fox to extensively renovate the building through 2022. As part of the renovation, the building was renumbered to 660 Fifth Avenue.

647 Fifth Avenue, originally known as the George W. Vanderbilt Residence, is a commercial building in the Midtown Manhattan neighborhood of New York City. It is along the east side of Fifth Avenue between 51st Street and 52nd Street. The building was designed by Hunt & Hunt as part of the "Marble Twins", a pair of houses at 645 and 647 Fifth Avenue. The houses were constructed between 1902 and 1905 as Vanderbilt family residences. Number 645 was occupied by William B. Osgood Field, while number 647 was owned by George W. Vanderbilt and rented to Robert Wilson Goelet; both were part of the Vanderbilt family by marriage. The house is a six-story stone building in the French Renaissance Revival style. The first floor has arched openings topped by a balustrade, while the second and third stories contain fluted pilasters supporting an entablature. The fourth and fifth floors were added in the late 1930s in an imitation of the original design, and a balustrade runs above the fifth story. The adjoining townhouse at 645 Fifth Avenue, demolished in 1944, had been built in a similar style. The entire building is taken up by a store for fashion company Versace, which also built a sixth-story fitting room. The southeast corner of Fifth Avenue and 52nd Street was planned as a hotel in the early 1900s after the Roman Catholic Asylum vacated the site. After the Vanderbilts blocked the development of the hotel, the southern portion of the site was developed as the Marble Twins, while the northern portion became the Morton F. Plant House (now the Cartier Building). Number 647 was altered for commercial use after 1916 and contained an art gallery and airline ticket agent, among other tenants. Number 645 was largely residential until it was torn down. The New York City Landmarks Preservation Commission designated 647 Fifth Avenue as a city landmark in 1977, and it was added to the National Register of Historic Places in 1983 along with the Cartier Building. In the late 1990s, Versace remodeled 647 Fifth Avenue.

Completed in 1935, the 41-story, 512 ft (156 m) building was designed in the Art Deco style by Raymond Hood, Rockefeller Center's lead architect. The main tower is set back from Fifth Avenue and includes two 6-story wings to the east, known as Palazzo d'Italia and International Building North. The wings flank an entrance plaza that contains Lee Lawrie's Atlas statue. The facade is made of limestone, with granite at the base. The wings, patterned around the British Empire Building and La Maison Francaise to the south, contain rooftop gardens. The building's entrances contain ornate decorations by numerous artists. The main entrance on Fifth Avenue leads to a four-story-tall lobby with large marble pillars and escalators. The office space is arranged around the elevator core, with all offices being within 27 feet (8.2 m) of a window. The entire Rockefeller Center complex is a New York City designated landmark and a National Historic Landmark, and the lobby is also a New York City landmark. The International Building was developed as part of the construction of Rockefeller Center, although plans for the building were modified multiple times. A groundbreaking ceremony was hosted in July 1933, after Italian interests leased the southern wing, but Rockefeller Center's managers could not secure a commitment for a specific country in the northern wing. The building's superstructure was constructed in 136 days from September 1934 to May 1935. The Palazzo d'Italia was modified in the 1940s after the start of World War II, and further modifications were made in the late 20th century. Over the years, the International Building has contained a variety of tenants, including numerous consulates.

The 52nd Street facade of the house contains an ornate pavilion, and both facades have an attic hidden inside a frieze. The Edward Holbrook House was also designed in a neoclassical style but has a mansard roof. Both houses are five stories tall and are connected internally. The Cartier store takes up all of the stories inside the building. The southeast corner of Fifth Avenue and 52nd Street was planned as a hotel in the early 1900s after the Roman Catholic Asylum vacated the site. After the Vanderbilts blocked the development of the hotel, the northern portion became the Morton F. Plant House, while the southern portion of the site was developed as the Marble Twins at 645 and 647 Fifth Avenue. In the late 1910s, Plant sold his house to Cartier. The Holbrook House was occupied by a variety of tenants until 1927, after which it was purchased by 653 Fifth Avenue's owners and used by various organizations and firms. The New York City Landmarks Preservation Commission designated the Cartier Building as a city landmark in 1970, and it was added to the National Register of Historic Places in 1983 along with 647 Fifth Avenue.
