The studio was added in 1926 by Lloyd Wright.","why_significant":"The nomination argues it is significant as Wright's first use of textile block construction and the only Wright house in Pasadena. It also cites the siting of the house in a ravine and the role of its client, Alice Millard, a rare-book dealer whose home became a center of cultural exchange in southern California.","narrative":"La Miniatura, known also as the Millard House, is a small residence and studio at 645 Prospect Crescent in Pasadena. Frank Lloyd Wright designed the main house, begun in 1923 for rare-book dealer Alice Millard, and his son Lloyd Wright added a matching rear studio in 1926. The house sits at the head of a wooded ravine and is built of patterned concrete textile blocks, knit together with steel and poured solid to form double walls. This was Wright's first house to use the method. He supervised the work daily, using unskilled labor, and varied the sand and concrete mix to produce tonal differences in the blocks. The design answered Millard's needs for a large living room, an interior balcony and space for her book collection. Millard also welcomed artists, students and book enthusiasts, which helped build a regional cultural network. The buildings have been altered little, apart from a 1931 garage designed to conform to the original style.","period_of_significance":"1900-","architect_builder":"Main House - Frank Lloyd Wright; Studio - Lloyd Wright after F.

The only changes to the original concept are the 1926 studio and a 1931 garage designed to conform.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:31.605183-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/76000493.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/76000493/8aa97bc09f-800.webp","url_1600":"https://nationalhistoricalregister.com/media/76000493/8aa97bc09f-1600.webp","licence":"CC BY-SA 3.0","author":"Los Angeles","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Millard_House,_Pasadena.JPG\" rel=\"noopener\">Los Angeles</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:Millard_House,_Pasadena.JPG"},"district":{"nrhp_refnum":"83001202","name":"Prospect Historic District","url":"https://nationalhistoricalregister.com/districts/california/prospect-historic-district-83001202/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123859317","wikipedia":"https://en.wikipedia.org/wiki/Millard_House_(Pasadena,_California)","wikidata":"https://www.wikidata.org/wiki/Q965011"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/los-angeles-county/millard-house-76000493/"}
