It retains rare original anchor-beam framing, stone foundation, weatherboards and a trimmer-beam fireplace framing detail. It also shows Albany's Dutch cultural heritage and the city's changing development, and it holds archeological deposits.","narrative":"Built in 1728 at 48 Hudson Avenue in Downtown Albany, this two-and-one-half-story house is a rare survivor of the city's Dutch period. Its seven structural bays of anchor-beam framing stand above a stone foundation, with original nogging bricks, hand-wrought nails and wide weatherboards still visible on the west side. Eight large anchor beams remain in the garret level, along with a trimmer beam that once supported a jambless fireplace hood, described as the only known surviving example of that framing. The building was widened around 1790, given a rear brick wing after 1835, and altered in the 1930s and again with a later storefront. Tree-ring dating and documents confirm the construction date. Only this house and the Quackenbush House remain from Albany's Dutch era within the city limits. The house is valued for its architecture, its link to early Dutch settlement and community development, and for archeological deposits found beside its west foundation wall. Surrounding historic buildings have been demolished, leaving it nearly isolated.","period_of_significance":"1728-1892","architect_builder":null,"architectural_style":"Colonial: Dutch Colonial; rear extension has no style (19th Century Industrial)","criteria":["A","C","D"],"status_note":"Current function listed as vacant/not in use; the rear addition was used as retail and storage until about 2000 and is undecorated and slightly deteriorated.","vacant_flag":true,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:52.779531-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/07000291.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/07000291/10da2460a8-800.webp","url_1600":"https://nationalhistoricalregister.com/media/07000291/10da2460a8-1600.webp","licence":"CC BY-SA 3.0","author":"UpstateNYer","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:48_Hudson_Ave_Albany.jpg\" rel=\"noopener\">UpstateNYer</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:48_Hudson_Ave_Albany.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75316371","wikipedia":"https://en.wikipedia.org/wiki/48_Hudson_Avenue","wikidata":"https://www.wikidata.org/wiki/Q4638646"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/albany-county/van-ostrande-radliff-house-07000291/"}
