It reflects the firm's contribution to Pasadena's regional residential Modernism and meets the registration requirements of the Pasadena Recent Past multiple property listing. It qualifies under Criterion C for architecture at the local level.","narrative":"Set on a short, steep cul-de-sac in Pasadena, this 1958 house at 512 Glen Court is a one-story, flat-roofed, T-shaped residence of about 1,700 square feet. It was designed by the architectural firm Buff, Straub and Hensman for Robert and Barbara Pike, who acted as their own contractor. Built of post-and-beam construction with stucco, wood and glass, it features exposed beams, tongue-and-groove ceilings, a long shaded entry path and a wall of glass in the living room. Unlike many of the firm's houses, it shows little Craftsman or Japanese influence, emphasizing spare, crisp horizontal lines. It was nominated as an excellent, well-preserved example of the firm's classic Mid-Century work and of Pasadena's Recent Past modernism, qualifying for architecture at the local level. A detached 1989 studio is noncontributing, and later changes such as added roof insulation, a replaced front door and new driveway pavers did not harm the house's overall integrity.","period_of_significance":"1958","architect_builder":"Buff, Smith & Hensman; Straub, Calvin","architectural_style":"Modern Movement","criteria":["C"],"status_note":"Still used as a single dwelling; a 1989 studio addition is noncontributing, and minor alterations (roof insulation, front door, driveway pavers, some windows) are described as not affecting integrity.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:29.81909-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/09000181.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/09000181/e098f426c8-800.webp","url_1600":"https://nationalhistoricalregister.com/media/09000181/e098f426c8-1600.webp","licence":"CC0","author":"TheCatalyst31","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Robert_and_Barbara_Pike_House.JPG\" rel=\"noopener\">TheCatalyst31</a>, <a href=\"http://creativecommons.org/publicdomain/zero/1.0/deed.en\" rel=\"license noopener\">CC0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Robert_and_Barbara_Pike_House.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123857581","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q133289538"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/los-angeles-county/pike-robert-and-barbara-house-09000181/"}
