Glasner. It sits on a wooded bluff above a ravine near Lake Michigan.","why_significant":"The nomination argues local significance under Criterion C for architecture as a Wright-designed Prairie-style house that retains most of its original integrity. Its plan, rustic board-and-batten walls, art glass windows and integration with the site are cited as characteristic of Wright. The open plan without a formal dining room is described as foreshadowing his later Usonian houses.","narrative":"Built in 1906 in Glencoe, Illinois, about twenty miles north of Chicago, this single-story house was designed by Frank Lloyd Wright for William A. Glasner. It sits low on a wooded bluff above a ravine that drains to Lake Michigan. Dark-stained board-and-batten walls, stucco above, a low hipped roof with wide eaves and more than fifty art glass windows give it a rustic look that blends with its surroundings. Octagonal rooms project toward the landscape, and the main entry leads straight into the living room, with no formal dining or reception room. Later owners, including architects Rudolph and Elizabeth Nedved, altered the basement, garage, landscaping and utilities, but the form says the original windows, plan and spatial relationship to the site largely survive. It was listed for its architecture, as a local example of Wright's Prairie work whose plan anticipated his later Usonian houses.","period_of_significance":"1906","architect_builder":"Wright, Frank Lloyd, architect","architectural_style":"Prairie School","criteria":["C"],"status_note":"Still in use as a single-family dwelling; the form describes past alterations, including a basement remodel, garage addition and kitchen remodel.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:37.135441-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/58/8920/28892058/content/electronic-records/rg-079/NPS_IL/05000105.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/05000105/3c37e95e90-800.webp","url_1600":"https://nationalhistoricalregister.com/media/05000105/3c37e95e90-1600.webp","licence":"CC BY-SA 4.0","author":"Zol87 from Chicago, Illinois, USA","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:William_A._Glasner_House.jpg\" rel=\"noopener\">Zol87 from Chicago, Illinois, USA</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:William_A._Glasner_House.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28892058","wikipedia":"https://en.wikipedia.org/wiki/William_A._Glasner_House","wikidata":"https://www.wikidata.org/wiki/Q8003956"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/cook-county/glasner-william-a-house-05000105/"}
