The Armour–Stiner House is a octagon-shaped and domed Victorian-style house located at 45 West Clinton Avenue in Irvington, in Westchester County, New York. It was designated a National Historic Landmark in 1976. It is the only known fully domed octagonal residence. The house was modeled after Donato Bramante’s 1502 Tempietto in Rome, which in turn was based on a Tholos, a type of ancient classical temple. The house was built in 1859–1860 by financier Paul J. Armour based on the architectural ideas of Orson Squire Fowler, the author of The Octagon House: A Home for All Occasions. Fowler believed that octagonal houses enclosed more space, provided more interior sunlight, and that its rooms were easily accessible to each other. Fowler's ideas gained significant traction in the mid-to-late 19th century. The architect of the house is unknown. It is the only known octagonal house based on the domed colonnade shape of a Roman temple. The dome was added and the house was enlarged during 1872–1876 by Joseph Stiner, who was a tea importer. The Armour–Stiner House is said to be one of the most lavish octagon houses built in the period, and is now one of only perhaps a hundred still extant.In the 1930s, the house was owned by Aleko E. E. Lilius, a Finnish writer and explorer, and from 1946 to 1976 by historian Carl Carmer, who maintained that the house was haunted. In 1976, the house was briefly owned by the National Trust for Historic Preservation to prevent it from being demolished. The Trust was unable to fund the amount of renovation the property required, and sold it to the preservationist architect, Joseph Pell Lombardi, who has conserved and renovated the house, interiors, grounds and outbuildings.The house remains a private residence. It is located on the south side of West Clinton Avenue, on the crest of a hill overlooking the Hudson River, to the west. It is about 1650 feet from the river, and about 140 feet above it, consistent with Fowler's siting ideas. The Old Croton Aqueduct, another National Historic Landmark, abuts the property on the east. In September 2017, Lombardi offered the house for rent through Sotheby's, for $40,000 a month.

Irvington, sometimes known as Irvington-on-Hudson, is an affluent suburban village in the town of Greenburgh in Westchester County, New York, United States. It is located on the eastern bank of the Hudson River, 20 miles (32 km) north of midtown Manhattan in New York City, and is served by a station stop on the Metro-North Hudson Line. To the north of Irvington is the village of Tarrytown, to the south the village of Dobbs Ferry, and to the east unincorporated parts of Greenburgh, including East Irvington. Irvington includes within its boundaries the community of Ardsley-on-Hudson, which has its own ZIP code and Metro-North station, but which should not be confused with the nearby village of Ardsley. The population of Irvington at the 2020 census was 6,652. Because many of Irvington's residents–especially those in the upper income brackets–live in Irvington and work in New York City, the village has a reputation as a "commuter town" or a "bedroom community".The village's half-mile-long (0.8 kilometers) Main Street area has been designated as a historic district by New York State and on January 15, 2014, was added to the National Register of Historic Places. In 2010, Westchester Magazine ranked Irvington as the "Best Place to Live in Westchester".
