It shows geometric massing, flat walls and roof, large glass expanses and minimal ornamentation, and it keeps its integrity of design, materials and feeling. It also carries Keck innovations such as a roof cooling pool and radiant floor heating, and won an AIA Citation of Merit in 1961.","narrative":"Built in 1957 on Sheridan Road in Kenilworth, Illinois, this one-story brick house was designed by the Chicago architects George Fred and William Keck working closely with its owner, Dr. Robert Hohf, a surgeon with an interest in design. Its flat roof, geometric massing, glass east wall facing Lake Michigan and sparse ornament follow International Style principles. The garage sits in front of the house, joined to it by a curved aluminum canopy. Rooms open off a central sunlit atrium with Asian-influenced screens, a small pool and cedar paneling. The Kecks also used experimental features, including radiant heated floors and a shallow roof cooling pool. The house won an AIA Citation of Merit in 1961. It was listed as an outstanding example of 1950s modern architecture in a village otherwise dominated by revival-style homes. Only air conditioning and a screened porch have been added, so its original character remains intact.","period_of_significance":"1957","architect_builder":"Architect: Keck and Keck (George Fred and William Keck); Builder: Wieboldt Construction Co.","architectural_style":"Modern Movement: International Style","criteria":["C"],"status_note":"Still a single dwelling, relatively unchanged since construction apart from added air conditioning and a screened porch; the form says it remains with its original owner.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:37.308846-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/52/8920/28892052/content/electronic-records/rg-079/NPS_IL/08001166.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/08001166/325d3ee427-800.webp","url_1600":"https://nationalhistoricalregister.com/media/08001166/325d3ee427-1600.webp","licence":"CC BY-SA 3.0","author":"Thshriver","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Hohf,_Dr_Robert_House_1.JPG\" rel=\"noopener\">Thshriver</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:Hohf,_Dr_Robert_House_1.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28892052","wikipedia":"https://en.wikipedia.org/wiki/Dr._Robert_Hohf_House","wikidata":"https://www.wikidata.org/wiki/Q15215004"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/cook-county/hohf-dr-robert-house-08001166/"}
