Its architects Janssen and Cocken and its builders Golden and Crick are described as important Pittsburgh firms. The form states that it is the last remaining warehouse and manufacturing area in downtown Pittsburgh and that its integrity is outstanding.","narrative":"Built in 1906 and 1907 on a corner of First Avenue in Pittsburgh, this seven-story brick and terra cotta building was designed by the architectural firm Janssen and Cocken and constructed by the contractors Golden and Crick. It was erected as a manufactory and warehouse for the Hartley-Rose Belting Company, which made leather belts for power transmission in steel mills and other industries. Leather was cut, cured and stretched on the open upper floors, where the wood beams on the seventh floor were used in the stretching process. The facade has an elaborate cornice with large modillions, acanthus leaf molding, quoins at the top floor and decorative spandrels, with a local sandstone first floor. It is listed for its Commercial Beaux-Arts design, its connection to a vanished industry central to Pittsburgh's growth, and its outstanding integrity as one of the few surviving warehouse buildings in the downtown area.","period_of_significance":"1906-1907","architect_builder":"Janssen and Cocken (architects); Golden and Crick (builders)","architectural_style":"Commercial Beaux-Arts","criteria":[],"status_note":"The form describes the building as well preserved and in excellent condition and unaltered apart from the main entrance door altered about 1960.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:32.297456-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/83002212.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/83002212/e4d468fc25-800.webp","url_1600":"https://nationalhistoricalregister.com/media/83002212/e4d468fc25-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Hartley-Rose_Belting_Company_Building.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Hartley-Rose_Belting_Company_Building.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71997748","wikipedia":"https://en.wikipedia.org/wiki/Hartley-Rose_Belting_Company_Building","wikidata":"https://www.wikidata.org/wiki/Q15223128"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/allegheny-county/hartley-rose-belting-company-building-83002212/"}
