Mason.","why_significant":"The nomination argues the house is an outstanding example of early twentieth-century residential architecture in Webster, combining Colonial Revival and Queen Anne elements with high-quality materials and craftsmanship. It is also tied to George G. Mason, its builder and first occupant, a long-time leader in the village's business and civic affairs. It is described as a reminder of Webster's early twentieth-century prosperity.","narrative":"Built in 1910 at 39 Dunning Avenue in Webster, this large brick and shingle house combines simple Queen Anne massing with Colonial Revival detail. It was built for George G. Mason, born in 1863, who ran a general store and pharmacy, constructed a three-story commercial building with an opera house in 1884, and co-founded the Jayne and Mason Bank in 1900. He also served as town clerk, four-term village president and a founder of the Webster Fire Department. To build here, Mason moved his earlier house and barn to a neighboring street. The house retains its original red tile roof, leaded and stained glass windows, Corinthian porch columns, white oak woodwork and inlaid hardwood floors. A carriage barn, now a garage, stands behind it. No architect has been identified, though the quality of the work suggests one may have been involved. The house is regarded as one of the village's finest early twentieth-century homes.","period_of_significance":"1910-1954","architect_builder":"unknown","architectural_style":"Queen Anne; Colonial Revival","criteria":["C"],"status_note":"Still in use as a single dwelling; the rear porch was converted to an all-season room and the carriage barn to a four-car garage.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:53.512231-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/04001206.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/04001206/2ded727b2e-800.webp","url_1600":"https://nationalhistoricalregister.com/media/04001206/2ded727b2e-1600.webp","licence":"CC BY-SA 3.0","author":"MohawkPhotographer","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:George_G-_Mason_House_2013-09-23_14-03-59.jpg\" rel=\"noopener\">MohawkPhotographer</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:George_G-_Mason_House_2013-09-23_14-03-59.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75318876","wikipedia":"https://en.wikipedia.org/wiki/George_G._Mason_House","wikidata":"https://www.wikidata.org/wiki/Q5539555"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/monroe-county/mason-george-g-house-04001206/"}
