Wright built the house for his family, and the studio was added later; the form gives dates of 1889, 1895 and 1898.","why_significant":"The nomination calls the building extremely well designed, responding to its site and use with very original details. It was the first house Wright designed for his own family. He lived and worked there during a very important creative period, when he designed buildings of international fame.","narrative":"Frank Lloyd Wright built this house in Oak Park, Illinois, for his own family, and later added a studio on the Chicago Avenue side of the lot. The original house has a common brick base and wood shingle siding, and is described as shingle style, reminiscent of work by Joseph Silsbee, for whom Wright had worked before joining Louis Sullivan. As the family grew, Wright changed the plan, enlarging the dining room and adding a vaulted playroom with a large fireplace, balconies and an unusual staircase. The bedrooms have clerestory dormer windows, and many windows are leaded glass. The studio wing added a library, lobby and a two-story drafting room with balconies, comparable on a small scale to Unity Temple, which was designed there. After Wright left his family, the studio was converted into rental apartments. The property matters as his first family home and as the place where he lived and worked during a highly creative period, producing buildings of international fame.","period_of_significance":"19th and 20th centuries; specific dates 1889, 1895, 1898","architect_builder":"Frank Lloyd Wright; sculpture by Richard Bock according to Wright's ideas","architectural_style":"Shingle style (original house)","criteria":[],"status_note":"Condition marked good and altered; the grounds are described as very well kept. Present use is marked as private residence and museum. The form says the studio space should be restored if shown to the public as originally designed.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:35.161488-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/18/8922/28892218/content/electronic-records/rg-079/NPS_IL/72000456.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/72000456/4cc5dd78b0-800.webp","url_1600":"https://nationalhistoricalregister.com/media/72000456/4cc5dd78b0-1600.webp","licence":"Public domain","author":"Related names: Wright, Frank Lloyd","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:ENTRANCE_TO_STUDIO,_LOOKING_SOUTHEAST_-_Frank_Lloyd_Wright_Home_and_Studio,_428_Forest_Avenue_and_951_Chicago_Avenue,_Oak_Park,_Cook_County,_IL_HABS_ILL,16-OAKPA,5-2.tif\" rel=\"noopener\">Related names: Wright, Frank Lloyd</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:ENTRANCE_TO_STUDIO,_LOOKING_SOUTHEAST_-_Frank_Lloyd_Wright_Home_and_Studio,_428_Forest_Avenue_and_951_Chicago_Avenue,_Oak_Park,_Cook_County,_IL_HABS_ILL,16-OAKPA,5-2.tif"},"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/28892218","wikipedia":"https://en.wikipedia.org/wiki/Frank_Lloyd_Wright_Home_and_Studio","wikidata":"https://www.wikidata.org/wiki/Q3069681"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/cook-county/wright-frank-lloyd-house-and-studio-72000456/"}
