It also represents the work of master architect Richard Neutra and marks a shift in his style from a cold machine aesthetic to warmer natural materials such as redwood and birch.","narrative":"Set on a steep hillside lot on the south side of Redlands, this single-story house was designed by Richard Neutra for Frederick and Mary Jane Auerbacher, who commissioned it in 1951. Completed in 1952, it is a post-and-beam building of about 2,300 square feet with a flat roof, redwood siding, some stucco and large areas of glass. The closed street side faces the slope, while the north side opens through floor-to-ceiling glass toward a rose garden, a golf course and the San Bernardino Mountains. Inside, birch paneling, redwood ceilings and a stone fireplace wall continue the materials used outdoors, and Neutra also designed much of the furniture. The house was listed for its architecture. It is presented as a strong example of mid-century modern design and as work from a turning point in Neutra's career, when warm natural materials replaced his earlier machine-like look. It retains nearly all of its original character.","period_of_significance":"1952","architect_builder":"Neutra, Richard","architectural_style":"Modern Movement, International Style (described in the significance statement as Mid-Century Modern)","criteria":["C"],"status_note":"Described as in excellent, near original condition, with the only major exterior alteration being a rooftop air conditioner and ductwork added in 1977; the form says it was still occupied by the original owner.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:29.623037-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/12000442.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/12000442/058073bfb7-800.webp","url_1600":"https://nationalhistoricalregister.com/media/12000442/058073bfb7-1600.webp","licence":"CC BY-SA 3.0","author":"Bruceherwig","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Auerbacher_Home.jpg\" rel=\"noopener\">Bruceherwig</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:Auerbacher_Home.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123860723","wikipedia":"https://en.wikipedia.org/wiki/Auerbacher_Home","wikidata":"https://www.wikidata.org/wiki/Q14681555"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/san-bernardino-county/auerbacher-home-12000442/"}
