It was built in 1909 and designed by the firm of Ballinger & Perrot.","why_significant":"The nomination argues the building is significant for its construction technology rather than its architecture, as an early and prominent use of reinforced concrete in a tall multi-story industrial building. The firm of Ballinger & Perrot is presented as among the first in Philadelphia to test, engineer, design and build reinforced concrete structures, and this building is described as a prototype for later Ballinger warehouses.","narrative":"Built in 1909 at 1238 Callowhill Street in Philadelphia, this eight-story warehouse is a reinforced concrete building designed by the architectural and engineering firm Ballinger & Perrot. Its main nine-bay section runs along 13th Street and fills its lot. The facade is organized into bands of regularly placed windows separated by spandrels and piers, with raised molded pilasters, straight stone lintels, and lion's head cartouches below the seventh-floor cornice. The interior follows industrial loft conventions, with open floors supported by columns and a continuous metal stair in the fire tower. Its eighth-floor sawtooth skylights are an early form of the type the firm later developed into its super-span roof. The building is important because it shows how reinforced concrete allowed taller, lighter industrial space with fewer columns. The firm's first concrete design, a Philadelphia machine shop of 1902, is cited as a precedent for this work.","period_of_significance":"1909","architect_builder":"Ballinger & Perrot (architect)","architectural_style":"Commercial style","criteria":[],"status_note":null,"vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:33.442071-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/85000469.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/85000469/f1333f8b37-800.webp","url_1600":"https://nationalhistoricalregister.com/media/85000469/f1333f8b37-1600.webp","licence":"Public domain","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Goodman_1238_Callowhill.JPG\" rel=\"noopener\">Smallbones</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Goodman_1238_Callowhill.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71997286","wikipedia":"https://en.wikipedia.org/wiki/Goodman_Brothers_and_Hinlein_Company","wikidata":"https://www.wikidata.org/wiki/Q5583454"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/philadelphia/goodman-brothers-and-hinlein-company-85000469/"}
