Armour and enlarged in 1872-1873 for merchant Joseph Stiner.","why_significant":"The house illustrates the octagon-house theories of phrenologist Orson Squire Fowler, including the octagonal plan, riverside siting and central stairwell. It is believed to be one of two domed octagonal residences in the United States. Its ornate design reflects the prosperity of its owners and 19th-century stylistic tastes.","narrative":"Set on a wooded three-acre rise about 145 feet above the Hudson River, this octagonal frame house in Irvington was built in 1860 for New York financier Paul J. Armour. It originally stood two stories tall. In 1872-1873 its second owner, tea importer Joseph Stiner, added the veranda, bay window, dome and cupola, raising the height to ninety-five feet. Inside, rooms are arranged around a central staircase running from the basement to the cupola. The interior retains plaster ceiling medallions, etched glass doors, newel-post lamps and Gothic Revival door moldings. The design follows ideas promoted by Orson Squire Fowler in his book on octagon houses, which favored the octagonal form and a central stairwell for efficiency and air circulation. The house is believed to be one of two domed octagonal residences in the United States. Later owners included naturalist Joseph Wood Krutch and author Carl Carmer. Little has been altered, so the house remains a distinctive local landmark.","period_of_significance":"1860; 1872-1873","architect_builder":null,"architectural_style":"Octagonal mode (eclectic, incorporating elements of several styles)","criteria":[],"status_note":"Occupied as a private residence at the time of nomination; condition listed as fair, with no significant alterations.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:39.176334-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/75001238.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/75001238/a87b8fbb42-800.webp","url_1600":"https://nationalhistoricalregister.com/media/75001238/a87b8fbb42-1600.webp","licence":"CC BY 2.0","author":"csouza_79","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Armour-Stiner_House_(1).jpg\" rel=\"noopener\">csouza_79</a>, <a href=\"https://creativecommons.org/licenses/by/2.0\" rel=\"license noopener\">CC BY 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Armour-Stiner_House_(1).jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75322943","wikipedia":"https://en.wikipedia.org/wiki/Armour%E2%80%93Stiner_House","wikidata":"https://www.wikidata.org/wiki/Q688901"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/westchester-county/armour-stiner-house-75001238/"}
