They form continuations of the earlier Strickland wings of the former Pennsylvania Institution for the Deaf and Dumb.","why_significant":"The nomination argues the addition is a work by Frank Furness, described as one of America's more influential nineteenth-century architects, and an example of his early institutional style. It also argues the wings complete a building complex that has served American education for over 150 years. The document calls the surviving structure a critical example of Furness's work.","narrative":"Two brick wings with sandstone trim stand at the western end of the Philadelphia College of Art complex, facing Pine, 15th and Delancey Streets. Completed in 1875 by the firm of Furness and Hewitt, they extend the earlier Strickland wings of the Pennsylvania Institution for the Deaf and Dumb, whose original building dates to 1824. The wings have steep slate hipped roofs, ornate bulbous chimneys, and dormer-gables with gothic arches set against a corbelled brick cornice. The 15th Street facades use progressively pointed arch windows from the first floor to the third. A small boiler house built in 1879 stands between the wings. The buildings are significant as a rare surviving example of Frank Furness's early institutional work, a architect the nomination describes as highly influential and as a teacher of Louis Sullivan. They are also part of a complex representing 150 years of American educational architecture, which the nomination treats as a reason for listing.","period_of_significance":"1874-1875","architect_builder":"Frank Furness (architect), Furness and Hewitt (firm)","architectural_style":null,"criteria":[],"status_note":"Altered: three chimneys lost their tops, some gables were replaced with shed dormers, several windows were bricked up or replaced, and skylights and enclosed bridges and galleries were added.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.239192-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/78002451.pdf"},"photo":null,"district":{"nrhp_refnum":"84003529","name":"Broad Street Historic District (Additional Documentation)","url":"https://nationalhistoricalregister.com/districts/pennsylvania/broad-street-historic-district-additional-documentation-84003529/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71997260","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/philadelphia/philadelphia-college-of-art-boundary-increase-78002451/"}
