Its plain plane surfaces, simple plan and low horizontal lines set it apart from the ornate period houses around it. It also relates to Chicago school skyscrapers and anticipates Wright's later horizontalism.","narrative":"Built in 1891-92 at 1365 North Astor Street in Chicago, this townhouse was commissioned by James Charnley, a wealthy lumberman and partner in Bradner, Charnley and Company. It has a basement, two stories and an attic, arranged around a central stair hall lit by a skylight. The walls are yellow Roman brick with limestone at the base, doorway and belt courses, and a stained wood balcony shows Wright's adaptation of Sullivan's ornament. A ten-foot addition at the south end was made in 1927. The house is cited in histories of both Sullivan and Wright as an early step toward modern architecture, built during an era of eclectic ostentation. Its flat surfaces, simple plan and low horizontal emphasis relate it to Chicago school skyscrapers such as the Monadnock and Wainwright buildings. Later owners included members of the Waller family, prominent in Chicago civic life. It was designated a Chicago landmark in 1958.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Described as in good condition, altered, on its original site, and occupied as a private residence at the time of nomination.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:35.583248-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/33/8925/28892533/content/electronic-records/rg-079/NPS_IL/70000232.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/70000232/6c9c00f385-800.webp","url_1600":"https://nationalhistoricalregister.com/media/70000232/6c9c00f385-1600.webp","licence":"Public domain","author":"Template:Frank Lloyd Wright","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:James_Charnley_Residence_HABS_ILL,16-CHIG,12-1.jpg\" rel=\"noopener\">Template:Frank Lloyd Wright</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:James_Charnley_Residence_HABS_ILL,16-CHIG,12-1.jpg"},"district":{"nrhp_refnum":"78001121","name":"Gold Coast Historic District","url":"https://nationalhistoricalregister.com/districts/illinois/gold-coast-historic-district-78001121/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28892533","wikipedia":"https://en.wikipedia.org/wiki/James_Charnley_House","wikidata":"https://www.wikidata.org/wiki/Q6131262"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/cook-county/charnley-james-house-70000232/"}
