Most houses date from 1935 to 1968.","why_significant":"The district is argued to be significant under Criterion C in architecture for its dense concentration of Modern residential design by a range of architects, from internationally known masters to local designers. It includes atypical early work by famous architects alongside houses showing their classic styles, such as Harwell Hamilton Harris's Laing House and Richard Neutra's Perkins House. Steep hillside sites and dense landscaping give the neighborhood a distinctive, cohesive character.","narrative":"Poppy Peak Historic District is a hillside neighborhood in the far southwest corner of Pasadena, next to Eagle Rock and Highland Park. Covering about 12.29 acres, it takes in portions of Poppy Peak Drive, Kaweah Drive, Cresthaven Drive and Pleasant Way. Developed from the 1920s subdivision of Poppy Peak, the area has narrow, winding streets, no sidewalks, and dense native and imported planting that partly hides many houses. Its houses, mostly built between 1935 and 1968, show a wide range of Modern residential design. Architects include Richard Neutra, Harwell Hamilton Harris, Leland Evison and Lyman Ennis, among others. The district includes Harris's Laing House, an International Style work unlike his mature output, and Neutra's Perkins House, a representative 1950s design. Steep slopes and limited building regulations shaped low, compact houses. Contributing and non-contributing houses sit together comfortably, giving the district a cohesive character recognized for its architecture.","period_of_significance":"1935-1968","architect_builder":"Multiple architects including Lyman Ennis, James Pulliam, Kenneth Hashimoto, Buff, Straub & Hensman, Leland Evison, Harwell Hamilton Harris, Richard Neutra, William Henry Taylor and Robert Cox","architectural_style":"Modern Movement","criteria":["C"],"status_note":"Houses are still in use as single dwellings, as listed under current function.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:29.67189-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/09000182.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/09000182/0b410b5171-800.webp","url_1600":"https://nationalhistoricalregister.com/media/09000182/0b410b5171-1600.webp","licence":"CC BY-SA 3.0","author":"TheCatalyst31","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Foot_of_Poppy_Peak_Drive.JPG\" rel=\"noopener\">TheCatalyst31</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:Foot_of_Poppy_Peak_Drive.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123857583","wikipedia":"https://en.wikipedia.org/wiki/Poppy_Peak_Historic_District","wikidata":"https://www.wikidata.org/wiki/Q16898725"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/los-angeles-county/poppy-peak-historic-district-09000182/"}
