It is unusual for its windowless exterior and central atrium in an established, traditional neighborhood. It blends the International Style with Japanese design and Prairie School influences, and qualifies under Criterion C.","narrative":"Often described as a square doughnut or a house without windows, this single-story brick residence at 734 Lenox Road in Glen Ellyn was designed by Paul Schweikher in 1953 for Dr. and Mrs. Alfred A. Schiller. It sits far back on its narrow lot and turns away from the street, with no exterior windows apart from a narrow sidelight at the door. Light and views come from a central glass-walled courtyard, which divides the plan into four wings. Interiors feature terrazzo floors, African mahogany paneling, and a cylindrical brick fireplace. Keck and Keck added a brick wing in 1964 that connected the house to its garage and matched the original materials and proportions. The property was listed for its architecture. It represents two prominent Chicago-area modernist firms and combines International Style design with Japanese-inspired elements and the textured modernism of the Prairie School, an unusual presence in an established traditional neighborhood.","period_of_significance":"1954; 1964","architect_builder":"Paul Schweikher & Winston Elting; George Fred Keck & William Keck","architectural_style":"International Style","criteria":["C"],"status_note":"Still in use as a single-family dwelling; some original interior features such as sliding doors and screens have been lost or altered by the current owner.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:37.689149-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/42/8927/28892742/content/electronic-records/rg-079/NPS_IL/08000326.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/08000326/78ad9210d9-800.webp","url_1600":"https://nationalhistoricalregister.com/media/08000326/78ad9210d9-1600.webp","licence":"CC BY-SA 3.0","author":"Teemu08 (talk)","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Alfred_A._Schiller_House.JPG\" rel=\"noopener\">Teemu08 (talk)</a>, <a href=\"https://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:Alfred_A._Schiller_House.JPG"},"district":{"nrhp_refnum":"100000628","name":"Lake Ellyn Park","url":"https://nationalhistoricalregister.com/districts/illinois/lake-ellyn-park-100000628/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28892742","wikipedia":"https://en.wikipedia.org/wiki/Alfred_A._Schiller_House","wikidata":"https://www.wikidata.org/wiki/Q4722198"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/dupage-county/schiller-alfred-a-house-08000326/"}
