The Villard Houses are a set of former residences comprising a historic landmark at 451–457 Madison Avenue between 50th and 51st Streets in the Midtown Manhattan neighborhood of New York City. Designed by the architect Joseph Morrill Wells of McKim, Mead & White in the Renaissance Revival style, the residences were erected in 1884 for railroad magnate Henry Villard. They comprise a portion of the Lotte New York Palace Hotel, the main tower of which is to the east. The building comprises six separate residences in a "U"-shaped plan, with wings to the north, east, and south surrounding a courtyard on Madison Avenue. The facade is made of Belleville sandstone, and each house consists of a raised basement, three stories, and an attic. Among the artists who worked on the interiors were artist John La Farge, sculptor Augustus Saint-Gaudens, and painter Maitland Armstrong. Some of the more elaborate spaces, such as the Gold Room, dining room, and reception area in the south wing of the complex, still exist as part of the New York Palace Hotel. The houses were commissioned by Henry Villard, president of the Northern Pacific Railway, shortly before he fell into bankruptcy. Ownership of the residences changed many times through the mid-20th century. By the late 1940s, the Roman Catholic Archdiocese of New York had acquired all of the houses, except the northernmost residence at 457 Madison Avenue, which it acquired from Random House in 1971. The New York City Landmarks Preservation Commission designated the complex an official landmark in 1968, and the residences were listed on the National Register of Historic Places in 1975. As part of the construction of the New York Palace Hotel, completed in 1980, the north wing was turned into office space for city preservation group Municipal Art Society.

Olympic Tower is a 51-story, 620 ft-tall (190 m) building at 641 and 645 Fifth Avenue, between 51st and 52nd Streets, in the Midtown Manhattan neighborhood of New York City. Designed by Skidmore, Owings & Merrill (SOM), the mixed-use development contains condominium apartments, office space, and retail shops. The tower is named after Olympic Airlines, whose president Aristotle Onassis jointly developed the tower with the Arlen Realty and Development Corporation between 1971 and 1974. It was the first skyscraper to be constructed within a special zoning district to encourage retail and mixed-use development along Fifth Avenue. The building's glass facade is designed to reflect St. Patrick's Cathedral immediately to the south. The superstructure is made of steel on the lower stories and cast concrete on the upper stories. The first two stories contain a public atrium, Olympic Place, which connects the 51st and 52nd Street facades. The next 19 stories contain office space while the top 30 stories contain 230 condominium apartments. Upon Olympic Tower's completion, architectural writers such as Ada Louise Huxtable and Christopher Gray criticized its design. Construction of Olympic Tower dates to the late 1960s, when Best & Co. sought to build an office tower above their store at Fifth Avenue and 51st Street. Morris Lapidus was initially hired for the project, but the plans were changed after the zoning district was created. When the building was completed, wealthy non-American buyers purchased most of its residential units. Crown Acquisitions bought Olympic Tower from its original owners in the 2010s.

Lotte New York Palace Hotel is a luxury hotel in the Midtown Manhattan neighborhood of New York City, at the corner of 50th Street and Madison Avenue. It was originally developed between 1977 and 1980 by Harry Helmsley. The hotel consists of a portion of the Villard Houses, built in the 1880s by McKim, Mead & White, which are New York City designated landmarks and listed on the National Register of Historic Places. It also includes a 51-story skyscraper designed by Emery Roth & Sons and completed in 1980. The Villard Houses, arranged in a U-shaped plan, consist of three wings surrounding a central courtyard on the east side of Madison Avenue. The houses' center wing serves as a lobby, while the south wing serves as an event space. Behind the Villard Houses to the east is the modern skyscraper addition. As of 2021, the hotel has 909 rooms and suites. The top floors of the skyscraper are known as the Towers, which consist of 176 luxury units. Among the units in the Towers are four ornate triplex suites, each with their own decorations, as well as four other specialty suites. The Helmsley Palace Hotel opened in 1981 and was operated by Helmsley until 1992. As part of a bankruptcy proceeding, it was sold in 1993 to the Sultan of Brunei, who completely renovated the hotel and Villard Houses. The government of Brunei took over the hotel from the royal family in the late 2000s. Northwood Investors, an American real estate investment firm, bought the hotel from the government of Brunei in 2011 and renovated it. The hotel was sold again in 2015 to Korean luxury hotel operator Lotte Hotels & Resorts, which renamed it the Lotte New York Palace Hotel.

The Cartier Building, also 653 Fifth Avenue, is a commercial building on the southeast corner of 52nd Street and Fifth Avenue in the Midtown Manhattan neighborhood of New York City. The building serves as the flagship store of Cartier in New York City. It consists of two conjoined residences completed in 1905: the Morton F. Plant residence at 651–653 Fifth Avenue, designed by Robert W. Gibson, and the Edward Holbrook residence at 4 East 52nd Street, designed by C. P. H. Gilbert. The Plant House was designed in the Neo-Renaissance style and has facades on both 52nd Street and Fifth Avenue. 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.

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.

12 East 53rd Street, also the Fisk–Harkness House, is a building in the Midtown Manhattan neighborhood of New York City. It is along the south side of 53rd Street between Madison Avenue and Fifth Avenue. The six-story building was designed by Griffith Thomas and was constructed in 1871. It was redesigned in the Tudor-inspired Gothic Revival style in 1906 by Raleigh C. Gildersleeve. The house had originally been designed as a four-story brownstone townhouse with a stoop, a raised basement, and a flat roof behind a galvanized-iron cornice. The present appearance of the house is a limestone structure designed in the Tudor-inspired Gothic Revival style. The asymmetrical facade contains two vertical bays, with a large main entrance on the left (east) bay and a triangular dormer on the right (west) bay. The interior floors of Thomas's original design were substantially altered to allow the three middle stories to have tall ceilings. The house was constructed for banking executive Charles Moran as a rowhouse with a brownstone facade, and a rear extension was constructed in the 1880s. The house was remodeled for Harvey and Mary Fisk, who bought the house in 1905. The Fisks sold it four years later to William Harkness and his wife Edith Harkness, the latter of whom sold the house in 1923. The house was then used for commercial tenants including art dealer Proctor & Company, the Automobile Club of America, and art dealer Symons Galleries. Since 1964 the building has been owned by LIM College. The New York City Landmarks Preservation Commission designated the house as an official landmark in 2010.
