20 East End Avenue

The York Avenue Estate (also known as the Avenue A Estate) is a historic complex of tenement buildings in the Yorkville neighborhood of Manhattan in New York City, New York, US. The complex occupies a city block bounded by FDR Drive and the East River to the east, 79th Street to the north, York Avenue to the west, and 78th Street to the south. The estate is one of the oldest buildings on the Upper East Side built by the City and Suburban Homes Company, a tenement developer. The buildings, along with the neighboring Cherokee Apartments, are listed on the National Register of Historic Places (NRHP) as the City and Suburban Homes Company's York Avenue Estate and Shively Sanitary Tenements Historic District. The York Avenue Estate was also designated by the New York City Landmarks Preservation Commission (LPC) as a city landmark. The York Avenue Estate consists of fourteen buildings, including a hotel. Harde & Short and Percy Griffin each designed two of the early buildings, while the others were designed by Philip Ohm. The buildings are all of the Beaux-Arts style, except for two Gothic Revival structures named for Episcopal bishop Henry C. Potter. They generally have similar details, floor plans, and materials. Except for the eight-story East End Hotel building at the estate's southeast corner, all the buildings are six stories high. The city block had been reserved for the New York Protestant Episcopal School but remained undeveloped into the 19th century. The City and Suburban Homes Company bought the western part of the block in 1901, while the rest of the block was acquired in 1905. Work proceeded in phases from York Avenue eastward and was completed in 1913. City and Suburban owned the buildings until 1961, when the company was bought out by the Diversified Management Corporation, operated by the Scheuer family. In 1986, Peter Kalikow bought all the buildings and threatened to demolish the entire estate. Following outcry, Kalikow revised his plans to call for the redevelopment of four buildings; amid continued outcry, the LPC designated the complex as a landmark in 1990. The complex was resold in 1993 and 1994 to a firm operated by Stanley Wasserman Cos., which renovated it.

The Octagon, built in 1834, is a historic octagonal building and attached apartment block complex located at 888 Main Street on Roosevelt Island in New York City. It originally served as the main entrance to the New York City Mental Health Hospital (also known as the New York City Lunatic Asylum), which opened in 1841. Designed by Alexander Jackson Davis, the five-story rotunda was made of blue-gray stone that was quarried on the island. The Octagon is the last remnant of the hospital, and after many years of decay and two fires, was close to ruin. After restoration, it has now been incorporated into the adjacent buildings to create a large apartment complex. Mistreatment of patients at the asylum was the center of the exposé by Nellie Bly in her 1887 book Ten Days in a Mad-House.
