Few comparable mid-19th-century houses survive there unaltered. It was built by Gideon Ives, who with partner Elmore J. Dennison ran the largest general store in Mercer County, and it has a mirror-image twin across the street.","narrative":"Built in 1857 at 408 East Jefferson Street in New Boston, Illinois, this two-story brick house combines Italianate design with Greek Revival details. It has an asymmetrical, cross-gabled plan, a central cupola, wide eaves with paired brackets, and tall windows topped with cast-iron hoods. The bricks were made on site. Inside, a curved cantilevered staircase with walnut rail and richly detailed woodwork reflect the transition between the two styles. Its original porches were removed in the 1970s, but photographs and the twin house across the street document them. Gideon Ives and his business partner Elmore J. Dennison operated the largest general store in Mercer County and built mirror-image homes facing each other, starting in 1855. The house was listed for its architecture, as an excellent local example of an asymmetrical Italianate home, in a town where most comparable mid-19th-century houses have been lost or heavily altered. A carriage house predating about 1880 stands on the lot.","period_of_significance":"1857","architect_builder":null,"architectural_style":"Italianate; Greek Revival","criteria":["C"],"status_note":"Described as in excellent condition, in use as a single dwelling, with an extensive rehabilitation in progress since 1997.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:37.145437-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/25/8937/28893725/content/electronic-records/rg-079/NPS_IL/00001332.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/00001332/09f9f7b4c5-800.webp","url_1600":"https://nationalhistoricalregister.com/media/00001332/09f9f7b4c5-1600.webp","licence":"CC BY-SA 4.0","author":"Magicpiano","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:NewBostonIL_GideonIvesHouse.jpg\" rel=\"noopener\">Magicpiano</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:NewBostonIL_GideonIvesHouse.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28893725","wikipedia":"https://en.wikipedia.org/wiki/Gideon_Ives_House","wikidata":"https://www.wikidata.org/wiki/Q23073904"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/mercer-county/ives-gideon-house-00001332/"}
