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.

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.

18 East 50th Street, also known as the Hampton Shops Building and the New York Health & Racquet Club Building, is an office building in the Midtown Manhattan neighborhood of New York City. Located on the south side of 50th Street, on the middle of the block between Fifth Avenue and Madison Avenue, it was designed by William Lawrence Rouse, Lafayette Anthony Goldstone, and Joseph L. Steinam. 18 East 50th Street is designed in the Neo-Gothic style, sometimes referred to as the Perpendicular Gothic style. The style was chosen because it complemented the St. Patrick's Cathedral complex across the street. The 11-story building has a facade of grey terracotta that resembles granite. The building has no setbacks, as it was built before zoning ordinances required them. The Hampton Shops, founded in the early 1860s as the Grand Rapids Furniture Company, sold traditionally-styled furniture. The building site was leased in 1914 and the store at 18 East 50th Street was constructed from June 1915 to March 1916. Hampton Shops subsequently acquired the lease before going bankrupt in 1938. The building was then divided up and leased to art and design businesses. The New York City Landmarks Preservation Commission designated 18 East 50th Street as an official landmark in 2016.

It is along Madison Avenue's western sidewalk between 51st and 52nd Streets, near St. Patrick's Cathedral. 488 Madison Avenue was designed by Emery Roth & Sons in the International Style, and it was constructed and developed by Uris Brothers.

The lowest two stories contain a main entrance on Madison Avenue as well as several glass-and-metal storefronts. The three sides are connected by curved walls. The exterior includes several setbacks to comply with the 1916 Zoning Resolution. Each of the building's stories contain an average floor area of 19,500 square feet (1,810 m2), a feature intended to maximize usable office space. 488 Madison Avenue was constructed from 1948 to 1950 as a speculative real estate development, without a main tenant. By late 1949, the building was completely leased, and it was named after Look magazine, which had signed a lease for several floors. 488 Madison Avenue remained the headquarters of Look until the magazine stopped publishing in 1971, although it continued to be known as the Look Building for several years. The building has been owned by John D. and Catherine T. MacArthur Foundation and The Feil Organization since the 1970s. The Look Building was added to the National Register of Historic Places in 2005, and the New York City Landmarks Preservation Commission designated it as an official landmark in 2010.

Mathews was constructed from 1901 to 1906. The cathedral was consecrated on October 5, 1910, after all its debt had been paid off.
