It is a Westchester Deluxe two-bedroom model.","why_significant":"The nomination argues it is an excellent, intact example of post-World War II prefabricated housing using porcelain-enameled steel panels. It meets Criterion A for its link to postwar efforts to relieve the housing shortage and Criterion C as a creative prefabricated design. It is one of 22 Lustron houses built in Georgia.","narrative":"Built around 1949 in Americus, Georgia, this one-story, side-gabled ranch house is a Lustron, a prefabricated home made of porcelain-enameled steel. It was erected by the Hav-A-Home Lustron franchise of Albany and is one of 22 built in Georgia and 2,498 produced nationwide. The 1,085-square-foot Westchester Deluxe two-bedroom model has tan two-foot-square exterior panels, dark blue tile-like roof shingles, aluminum casement windows and a bay window in the living room. Inside, steel panels cover the walls and ceilings, and built-in steel furniture, a buffet with pass-through, and sliding doors remain. It is considered significant as an intact example of postwar prefabricated housing, an innovative response to the housing shortage after World War II, and as a modern, functional design that departed from revival-style homes. Although less than fifty years old at the time of listing, it was accepted because recent research on Lustron houses allows objective evaluation.","period_of_significance":"c. 1949","architect_builder":"Roy Blass and Morris Beckman - Illinois architects (designed prototype for the Porcelain Products Company, later renamed Lustron Corporation)","architectural_style":"Other: Lustron","criteria":["A","C"],"status_note":"Still in use as a single dwelling; the form says it retains complete structural and architectural integrity, though the original combination dishwasher/clothes washer was removed.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:43.395308-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_GA/96000209.pdf"},"photo":null,"district":{"nrhp_refnum":"76000648","name":"Americus Historic District","url":"https://nationalhistoricalregister.com/districts/georgia/americus-historic-district-76000648/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/93206610","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q134457576"},"indexable":true,"url":"https://nationalhistoricalregister.com/georgia/sumter-county/lustron-house-at-547-oak-avenue-96000209/"}
