A one-story rear wing was completed in 1830 and a two-story front section was built in 1847.","why_significant":"The nomination calls the house an excellent example of a Greek Revival influenced town house and the best example in its locale. Its position on U.S. 35 gives it high regional visibility. The 1830 wing is tied to pioneer builder Jacob Sorber, and the front section to George B. Unger, a local clerk and merchant's son-in-law.","narrative":"This house at 29 East Dayton Street in West Alexandria, Ohio, was built in two stages and has an L-shaped plan. A plain, one-story vernacular wing at the rear was completed in 1830 by pioneer Jacob Sorber, who set up a sawmill on Twin Creek and built much of the town's early architecture. The two-story front section, dating to 1847, has a symmetrical five-bay Flemish bond brick facade facing south, a stone-linteled doorway with pilasters, transom and sidelights, and star-shaped tie rod ends. Inside, a central hall separates single rooms on each side, with austere Greek Revival trim. George B. Unger, a Pennsylvania native who became a clerk and later married his employer's daughter, owned the property when the front was built, and his home was considered a local showplace. The house is described as the best example of its type in the area, and its location on U.S. 35, part of the Dayton cutoff of the Old National Road, gives it wide visibility.","period_of_significance":"1800-1899","architect_builder":"1830 - Jacob Sorber (spelled Serber in earlier drafts); 1847 - John Zitzer (spelled Sitzer in earlier drafts)","architectural_style":"Greek Revival influence (L-plan town house)","criteria":[],"status_note":"Private residence, occupied; a frame garage/workshop was added to the rear of the 1830 wing.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:12.596848-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/78002176.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/78002176/2f80564c3d-800.webp","url_1600":"https://nationalhistoricalregister.com/media/78002176/2f80564c3d-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:George_B._Unger_House.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:George_B._Unger_House.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71991043","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q138657154"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/preble-county/unger-george-b-house-78002176/"}
