W. Dickinson.","why_significant":"The district is nominated under Criterion C for architecture as a cohesive group of Craftsman and Prairie-influenced houses tied to the Arts and Crafts Movement. Twelve of the fifteen houses are bungalows, and the group shows repeated features such as art-glass windows, box-like bay windows, and flower box brackets. It is described as the only cohesive grouping of these styles in Wilmette.","narrative":"Oak Circle is a short, curving, brick-paved street in Wilmette, Illinois, lined with fifteen houses and eleven garages built between about 1919 and the mid-1920s. Twelve of the houses are bungalows, and the rest show Craftsman influence, often with Prairie-style details. Common features include brick lower stories, wood shingles under the gables, exposed rafter tails, box-like bay windows, flower box brackets, and bands of zinc-framed art-glass windows. Three of the bungalows are the so-called airplane type, with a half-story set above a wider lower floor. Builder A. W. Dickinson resubdivided the area in 1920 and obtained permits for the seven east-side homes, and the similarity of the west-side houses suggests he or like-minded builders were involved there as well. The district was listed for its architecture, as a cohesive grouping of Arts and Crafts era houses that Wilmette has no other example of. Fourteen of the fifteen houses are counted as contributing.","period_of_significance":"c. 1919 to c. 1927","architect_builder":"Dickinson, A.W., Builder","architectural_style":"Prairie School - Bungalow/Craftsman","criteria":["C"],"status_note":"Historic and current use is domestic, single dwellings with secondary structures (garages); the street retains its brick paving and most original house integrity.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:37.659988-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/78/8920/28892078/content/electronic-records/rg-079/NPS_IL/01000668.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/01000668/800a3a170d-800.webp","url_1600":"https://nationalhistoricalregister.com/media/01000668/800a3a170d-1600.webp","licence":"CC BY-SA 3.0","author":"G LeTourneau","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Oak_Circle_HD_-_344_05.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:Oak_Circle_HD_-_344_05.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28892078","wikipedia":"https://en.wikipedia.org/wiki/Oak_Circle_Historic_District","wikidata":"https://www.wikidata.org/wiki/Q7073436"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/cook-county/oak-circle-historic-district-01000668/"}
