It shows a cruciform plan, flowing interior spaces, horizontal lines, earth-toned natural materials and a design fitted to its ravine site.","narrative":"Ravine Place, at 637 North Batavia Avenue in Batavia, Illinois, is a Prairie School house designed by Frank Lloyd Wright in September 1906 for Mrs. A. W. Gridley. It sits on a wooded 2.3-acre lot beside a gently sloping wildflower ravine. The house has earth-toned stucco walls, light brown cedar trim, a low hipped roof with wide eaves, and bands of mullioned windows. Its cruciform plan includes a long one-story south porch reaching toward the ravine, and inside the rooms flow into one another around Roman brick fireplaces and oak built-ins. It was listed for its architecture, as the work of a master and a strong example of Wright's Prairie period, comparable to his Willits and Little houses. Later changes include repairs after 1940s water damage, restuccoing in 1987, and a 1992 kitchen addition. A circa 1880 carriage barn was moved to the lot in 1988. The house remains a single-family home.","period_of_significance":"1906","architect_builder":"Wright, Frank Lloyd","architectural_style":"Prairie School","criteria":["C"],"status_note":"Still a single-family dwelling; repaired and renovated in 1987 and 1992, including a new kitchen addition, and a circa 1880 carriage barn was moved onto the property in 1988 (noncontributing).","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:37.75384-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/32/8931/28893132/content/electronic-records/rg-079/NPS_IL/92001850.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/92001850/a7ae01e0cd-800.webp","url_1600":"https://nationalhistoricalregister.com/media/92001850/a7ae01e0cd-1600.webp","licence":"CC BY-SA 3.0","author":"G LeTourneau","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Mrs._A._W._Gridley_House_(Batavia,_IL)_02.JPG\" rel=\"noopener\">G LeTourneau</a>, <a href=\"http://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:Mrs._A._W._Gridley_House_(Batavia,_IL)_02.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28893132","wikipedia":"https://en.wikipedia.org/wiki/Mrs._A._W._Gridley_House","wikidata":"https://www.wikidata.org/wiki/Q12059131"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/kane-county/gridley-mrs-a-w-house-92001850/"}
