The main block dates from the late eighteenth or early nineteenth century.","why_significant":"The nomination argues the house is architecturally significant as an example of Hudson Valley stone dwelling architecture. It is one of only seven two-story masonry houses among the fifty-six surviving pre-1850 masonry dwellings in Rochester. Its rear wing is one of eleven one-and-one-half story houses with an all-stone gable end. It is also tied to the Hoornbeck family and a former mill site.","narrative":"Beside Mill Brook on Boice Mill Road in Rochester, Ulster County, stands a stone dwelling made up of two connected sections. The older part is a one-and-one-half story eighteenth-century stone wing, now the rear kitchen portion. Set at right angles to it is a balanced two-and-one-half story main block built in the Georgian tradition, with a five-bay south front and a central entry with sidelights and transom. Inside, a center hall and double-pile plan survives with finishes in a high state of preservation. The house is significant as a typical but uncommon two-story example among Rochester's early masonry houses; only seven such dwellings were identified before 1850. Its rear wing also has an all-stone gable end, a feature found in just eleven local houses. The property is further linked to the Hoornbeck family, who obtained water rights here in 1703 for a grist mill and saw mill later run by the Dunn family.","period_of_significance":"ca.1800","architect_builder":null,"architectural_style":"Georgian tradition; classified as OTHER/vernacular","criteria":["C"],"status_note":"Still in use as a single dwelling; finishes are described as surviving in a high state of preservation despite limited nineteenth-century alterations.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:50.5735-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/97000108.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/97000108/bcdec56a09-800.webp","url_1600":"https://nationalhistoricalregister.com/media/97000108/bcdec56a09-1600.webp","licence":"CC BY-SA 3.0","author":"Daniel Case","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Jacob_Hoornbeck_Stone_House,_Kerhonkson,_NY.jpg\" rel=\"noopener\">Daniel Case</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:Jacob_Hoornbeck_Stone_House,_Kerhonkson,_NY.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75315250","wikipedia":"https://en.wikipedia.org/wiki/Jacob_Hoornbeck_Stone_House","wikidata":"https://www.wikidata.org/wiki/Q6118768"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/ulster-county/hoornbeck-jacob-stone-house-97000108/"}
