It also represents community planning in Rancho Santa Fe as part of a carefully laid out group of buildings in a large planned area. It was built under the strict architectural guidelines and Art Jury approval that governed the community.","narrative":"Built in 1927 at 5610 La Crescenta in Rancho Santa Fe, this large Spanish Colonial Revival house was designed by architect Lilian Rice for Charles A. Shaffer, a representative of Dupont interests and manager of the Dupont Nitrate Company of South America. The U-shaped, one-and-a-half-story house has about 5,067 square feet of living space, stucco walls, a red clay tile roof, and a patio at the center rear. Its features include a rectangular bell tower reached by a stairwell reminiscent of California missions, an arched recessed entry, corbeling, exposed rafter tails, window grillwork, and an arcade running between the wings. Despite these details, the facades remain clean and uncluttered. The estate once covered 250 acres, and later homes and roads reduced the original tract. The house was built under the community's strict design guidelines and Art Jury review. It is considered an excellent example of Rice's large-estate work and of the planned community's architecture.","period_of_significance":"1927","architect_builder":"Rice, Lilian Jenette","architectural_style":"Spanish Colonial Revival","criteria":["C"],"status_note":"Still in use as a single-family residence; the form notes a 1971 interior conversion, an early 1980s swimming pool, and a poorly built attached garage or storage area that could be removed.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:27.443655-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/91000944.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/91000944/cc75aeb913-800.webp","url_1600":"https://nationalhistoricalregister.com/media/91000944/cc75aeb913-1600.webp","licence":"Public domain","author":"Jack E.
