Both houses were designed by the Pittsburgh firm Carpenter & Crocker for attorney Willis F. McCook, and the nomination describes them as a cohesive estate with high-style interiors and craftsmanship.","narrative":"Two houses on an approximately .85 acre corner lot at Amberson and Fifth Avenues in Pittsburgh's Shadyside section make up the McCook Family Estate. The brick Tudor Revival house at 925 Amberson Avenue was completed in 1906 for Bessie McCook Reed, and the stone Elizabethan Revival mansion at 5105 Fifth Avenue followed in 1906-07 for her father, the lawyer Willis F. McCook. Carpenter & Crocker, a short-lived Pittsburgh partnership, designed both. The larger house has a stair hall, carved oak paneling, and a dining room with a tiled fireplace surround, and the smaller one has oak wainscoting and Tudor arches. The estate is valued for its design quality and for its place among the Fifth Avenue mansions built by Pittsburgh's wealthiest families, including Henry Clay Frick. Both houses were later divided and rented, and the mansion suffered fire damage in 2004.","period_of_significance":"1906-1907","architect_builder":"Carpenter & Crocker (architects)","architectural_style":"Tudor Revival; Elizabethan Revival","criteria":["C"],"status_note":"Vacant in the early 1940s after years of changing use; under historic rehabilitation into a hotel in 2010.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:10:27.075178-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/11000197.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/11000197/df02708996-800.webp","url_1600":"https://nationalhistoricalregister.com/media/11000197/df02708996-1600.webp","licence":"CC0","author":"Daderot","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:McCook_Mansion_-_Pittsburgh,_PA_-_DSC05088-001.JPG\" rel=\"noopener\">Daderot</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:McCook_Mansion_-_Pittsburgh,_PA_-_DSC05088-001.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71997682","wikipedia":"https://en.wikipedia.org/wiki/McCook_Family_Estate","wikidata":"https://www.wikidata.org/wiki/Q15252522"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/allegheny-county/mccook-family-estate-11000197/"}
