It was designed by Henry L. Kamphoefner with George Matsumoto and built of wood, brick and glass.","why_significant":"The house is nominated for architecture as an early modern, Wrightian Usonian house in an architecturally conservative Raleigh. It is associated with the 1948 founding of the NC State School of Design. The form credits three design ideas: a Wright-inspired configuration of space, passive climate control, and privacy tied to the owners' living habits.","narrative":"Completed in February 1950 at 3060 Granville Drive in Raleigh's Country Club Hills, this one-story house was designed by Henry L. Kamphoefner, first dean of North Carolina State's School of Design, with faculty member George Matsumoto. Its T-shaped plan uses wood, brick and glass, with a Roman brick chimney, copper and flat roofs, deep eaves and a large glass wall facing a golf course fairway. Interior features include birch plywood paneling, built-in furniture and radiant floor heating. Kamphoefner drew on Frank Lloyd Wright's Usonian designs and added his own passive ventilation scheme, though air-conditioning was installed in 1955 because humidity defeated it. The house is listed for architecture. It was among the first modern houses built in an architecturally conservative Raleigh, and it hosted seminars and visiting architects during Kamphoefner's years as dean. Changes include a red paint finish, repairs after Hurricane Hazel in 1954, and an extended terrace in 1963.","period_of_significance":"1950","architect_builder":"KAMPHOEFNER, HENRY L. architect; MATSUMOTO, GEORGE, associate; THOMPSON, J.M., builder","architectural_style":"Other: Wrightian Usonian","criteria":["C"],"status_note":"Still a single-dwelling residence; the form says it retains original integrity apart from four changes, and that the owner rents it to tenants.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:57:50.257936-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/81/7185/47718581/content/electronic-records/rg-079/NPS_NC/96000197.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/47718581","wikipedia":"https://en.wikipedia.org/wiki/Henry_L._Kamphoefner_House","wikidata":"https://www.wikidata.org/wiki/Q14707964"},"indexable":true,"url":"https://nationalhistoricalregister.com/north-carolina/wake-county/kamphoefner-henry-l-house-96000197/"}
