The material available is an administrative locator card rather than a nomination narrative, so it says nothing about the house's design, construction date, builder, architect or use. The card's status boxes mark the property as a National Historic Landmark and show that the nomination folder is missing from the files. Because no description or statement of significance appears in the text, the reasons for the listing cannot be given from this document. Anyone wanting details on the architecture and history of the house would need to consult other sources, such as the landmark documentation or the original nomination file, if it is later found.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":null,"vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:35.450247-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/77/8926/28892677/content/electronic-records/rg-079/NPS_IL/00000258.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/00000258/20ecf72479-800.webp","url_1600":"https://nationalhistoricalregister.com/media/00000258/20ecf72479-1600.webp","licence":"CC BY 2.5","author":"IvoShandor","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Oak_Park_Il_Heurtley_House4.jpg\" rel=\"noopener\">IvoShandor</a>, <a href=\"https://creativecommons.org/licenses/by/2.5\" rel=\"license noopener\">CC BY 2.5</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Oak_Park_Il_Heurtley_House4.jpg"},"district":{"nrhp_refnum":"08001096","name":"Frank Lloyd Wright-Prairie School of Architecture Historic District (Boundary Increase)","url":"https://nationalhistoricalregister.com/districts/illinois/frank-lloyd-wright-prairie-school-of-architecture-historic-district-boundary-inc-08001096/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28892677","wikipedia":"https://en.wikipedia.org/wiki/Arthur_Heurtley_House","wikidata":"https://www.wikidata.org/wiki/Q4799055"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/cook-county/heurtley-arthur-house-00000258/"}
