It stands in the center of the Knollwood Country Club, one of the first homes built on the club grounds. The building is horizontal and asymmetrical, with a flat roof, set-back upper story, smooth stucco over brick and concrete, steel-case windows and red-painted metal railings meant to suggest speed and a steamship. Inside, Art Deco details include a stepped limestone fireplace, etched mirrors, geometric light fixtures and baseboards, and a basement game room and tavern with Streamlined Moderne curves. Changes have been limited: a four-car attached garage was added in 1979, and in 1998 the coach house was separated onto its own lot. The house is recognized as a locally significant example of early Art Moderne design with classical Art Deco detailing.","period_of_significance":"1932","architect_builder":"Zimmerman, Saxe and Zimmerman, Architects","architectural_style":"Art Moderne; Art Deco","criteria":["C"],"status_note":"Listed current function is single-family domestic use; the property was split in 1998 so the coach house is now a separate residence.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:37.263492-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/86/8932/28893286/content/electronic-records/rg-079/NPS_IL/00000947.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/00000947/7ea8a04dcb-800.webp","url_1600":"https://nationalhistoricalregister.com/media/00000947/7ea8a04dcb-1600.webp","licence":"CC BY-SA 3.0","author":"Boscophotos","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Image_Hosmer_Morse_House.jpeg\" rel=\"noopener\">Boscophotos</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:Image_Hosmer_Morse_House.jpeg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28893286","wikipedia":"https://en.wikipedia.org/wiki/Robert_Hosmer_Morse_House","wikidata":"https://www.wikidata.org/wiki/Q86753184"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/lake-county/morse-robert-hosmer-house-00000947/"}
