The buildings range from the late 19th century to the 1920s.","why_significant":"The nomination argues the four buildings are in keeping with the commercial and architectural significance of the existing district, and that they fill a gap left when the original 1988 boundaries excluded them on the assumption they would join the Rittenhouse Historic District. It identifies 1501-1503 Locust Street as the building distinct enough to qualify under Criterion C, and the area as a whole as an example of the district's commercial development under Criterion A.","narrative":"Four commercial buildings at the southern edge of Center City West in Philadelphia make up this boundary increase to the Center City West Commercial Historic District. The group includes two small late-19th-century buildings on South 15th Street, one of them a Victorian brick building dating to about 1895 with a bay window and denticulated cornice, and two Locust Street buildings. The most prominent is 1501-1503 Locust Street, an eight-story Classical Revival commercial building designed in 1922 by Philadelphia architect LeRoy Rothschild for the Heymann Brothers, local real estate brokers. It has a steel frame clad in red-brown brick, with terra cotta cornices and Ionic capitals. The nomination lists the group for its role in the commercial development of the area and for the range of styles it shows, from late Victorian to Classical Revival. Building 222 S. 15th Street was altered after the period of significance and is classed as non-contributing.","period_of_significance":"1830-1941","architect_builder":"Rothschild, LeRoy Berman (architect of 1501-1503 Locust Street)","architectural_style":"Classical Revival","criteria":["A","C"],"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 17:10:27.549889-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/09000388.pdf"},"photo":null,"district":{"nrhp_refnum":"87002203","name":"Center City West Commercial Historic District","url":"https://nationalhistoricalregister.com/districts/pennsylvania/center-city-west-commercial-historic-district-87002203/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71997116","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/philadelphia/center-city-west-commercial-historic-district-boundary-increase-09000388/"}
