It is described as one of the last intact temple-style Greek Revival houses in the Lower Miami Valley. The earlier stone structure is also valued as a surviving relic.","narrative":"Set on a bluff above the Ohio River in Cincinnati's Riverside neighborhood, this house was built in two phases. The first is a single-level fieldstone building from about 1807, now used as the kitchen. The main two-story wood-frame house followed in 1840. Its front faces south with a temple-style portico: four fluted Doric columns carry a classical pediment, spaced wider than tradition would dictate to suit the broad floor plan. Inside, a center-hall plan has twin parlors, a dining room, a library and a narrow stair hall, with large rooms, poplar woodwork, grain-painted trim and wide pine floors. The form describes the house as a rare surviving example of tetrastyle, gable-front Greek Revival architecture in the Miami Valley, since most comparable Cincinnati buildings have been demolished. The old stone portion adds interest as an early survivor. A 2004 rear addition modernized the kitchen while leaving the principal facade and main rooms largely untouched.","period_of_significance":"c. 1807-1840","architect_builder":null,"architectural_style":"Greek Revival","criteria":["C"],"status_note":"Still used as a single-family dwelling; a rear addition and exterior restoration work were done in 2004.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:52:06.977498-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/05000341.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/05000341/415b8a20fb-800.webp","url_1600":"https://nationalhistoricalregister.com/media/05000341/415b8a20fb-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Matthew_McWilliams_House.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Matthew_McWilliams_House.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71988899","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q138349096"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/hamilton-county/mcwilliams-matthew-house-05000341/"}
