It was found eligible on that association, together with its groves, workshop, residence and its architectural, artistic and aesthetic character. The buildings were moved to preserve them when a state highway extension affected the original site.","narrative":"This 5.5-acre compound in the Alta Loma area of Rancho Cucamonga was the home and workshop of woodworker Sam Maloof and his wife Alfreda. Three buildings contribute to its character: the Main House, Guesthouse and Workshop 1, built between 1956 and 1976. The wood-framed house grew through more than a dozen additions over four decades, giving it varied rooflines, towers, redwood board siding, and hand-made window surrounds, doors and latches. In 1999-2000 the three buildings were moved about 2.5 miles from Highland Avenue to Carnelian Street under an agreement tied to a state highway extension. Workshop 2 was reconstructed from salvaged cladding, and trees, citrus groves and eucalyptus windbreaks were recreated or relocated to echo the original setting. Eight newer buildings and a gravesite do not contribute. The property was recognized for its close association with Maloof as a master craftsman and furniture maker, and for its workshop, residence and setting.","period_of_significance":null,"architect_builder":"Sam Maloof (designer and builder of the house and workshops)","architectural_style":"Other: Contemporary","criteria":[],"status_note":"Main House, Guesthouse and Workshop 1 were relocated in 1999-2000 to the current site; current functions include museum and specialty store (showroom) and single dwelling.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:29.644976-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/03000471.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/03000471/5da75e0320-800.webp","url_1600":"https://nationalhistoricalregister.com/media/03000471/5da75e0320-1600.webp","licence":"Public domain","author":"Bill W Ca at English Wikipedia","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:MaloofHouse.jpg\" rel=\"noopener\">Bill W Ca at English Wikipedia</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:MaloofHouse.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123860772","wikipedia":"https://en.wikipedia.org/wiki/Sam_and_Alfreda_Maloof_Compound","wikidata":"https://www.wikidata.org/wiki/Q22078116"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/san-bernardino-county/maloof-sam-and-alfreda-compound-03000471/"}
