It is a rectangular braced frame building with a limestone block foundation, a gable roof with shingles, and a five-bay front. Wood siding added in 1952 covers the original black walnut siding, and the foundation walls have been repaired and stuccoed. Inside, the original fireplaces, woodwork and ash floors survive in good condition. It is considered the oldest of the early 19th century braced frame houses in Worthington still in an excellent state of preservation. In the 1850s it was the home of Rev. Uriah Heath, a Methodist minister who helped found the Worthington Female Seminary. The house sits on a corner lot of less than an acre, with homes on three sides, and its exterior appearance has been compared to a New England home.","period_of_significance":"1818","architect_builder":null,"architectural_style":"Federal","criteria":[],"status_note":"Used as a residence; interior and exterior condition both described as good.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:11.997882-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/80003005.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003005/50e592f5a4-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003005/50e592f5a4-1600.webp","licence":"Public domain","author":"Springfieldohio at English Wikipedia","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Demas_Adams_House_8-3-08.jpg\" rel=\"noopener\">Springfieldohio at English Wikipedia</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Demas_Adams_House_8-3-08.jpg"},"district":{"nrhp_refnum":"10000190","name":"Worthington Historic District","url":"https://nationalhistoricalregister.com/districts/ohio/worthington-historic-district-10000190/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71985256","wikipedia":"https://en.wikipedia.org/wiki/Demas_Adams_House","wikidata":"https://www.wikidata.org/wiki/Q5255086"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/franklin-county/adams-demas-house-80003005/"}
