It was designed by Daniel Hudson Burnham.","why_significant":"The nomination argues the building is an excellent example of Burnham's later work, combining Chicago School steel-frame construction with Classical features. It is presented as the start of the age of the skyscraper in Pittsburgh, and the document places it within the wider development of the tall office building following affordable steel and the elevator.","narrative":"Built in 1901 in downtown Pittsburgh on Grant Street, the Frick Building is a twenty-one story office tower designed by Chicago architect Daniel Hudson Burnham for industrialist Henry Clay Frick. It combines a steel skeleton frame of the Chicago School with Classical detailing, including a temple-like base with Greek Doric columns and bronze-framed plate glass windows, and a monumental top. The marble lobby has curving stone stairways, two bronze lions beside the main door, and a stained glass window by John LaFarge. Sculptor J. P. Proctor, a student of Saint-Gaudens, made a statue for the lobby. The building is regarded as a leading example of Burnham's later work and as the beginning of the skyscraper era in Pittsburgh. An eighteen-story annex built behind it in 1905 across an alley is similar in appearance but lacks the Classical features. The upper floors remain in office use.","period_of_significance":"1901","architect_builder":"Daniel Hudson Burnham (architect)","architectural_style":"Chicago School with Classical features","criteria":[],"status_note":"The document says the upper stories are used for offices and the lobby holds a bank branch and a library business branch.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:29.899825-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/78002336.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/78002336/3f6a1a2067-800.webp","url_1600":"https://nationalhistoricalregister.com/media/78002336/3f6a1a2067-1600.webp","licence":"CC BY-SA 3.0","author":"TheZachMorrisExperience","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:FrickBuildingPittsburgh.jpg\" rel=\"noopener\">TheZachMorrisExperience</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:FrickBuildingPittsburgh.jpg"},"district":{"nrhp_refnum":"85003216","name":"Pittsburgh Central Downtown Historic District","url":"https://nationalhistoricalregister.com/districts/pennsylvania/pittsburgh-central-downtown-historic-district-85003216/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71997632","wikipedia":"https://en.wikipedia.org/wiki/Frick_Building","wikidata":"https://www.wikidata.org/wiki/Q175182"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/allegheny-county/frick-building-and-annex-78002336/"}
