The houses were built roughly between 1855 and 1864.","why_significant":"The nomination describes the block as one of the handsomest and best preserved mid-19th-century suburban streetscapes in Philadelphia, with a unity created by repeated porches, bracketed cornices and common stucco and masonry. It also links the houses to the suburban house ideals promoted by Andrew Jackson Downing and to early residents who were prominent in the city and at the University of Pennsylvania.","narrative":"Along the 4000 block of Pine Street in West Philadelphia stands a group of Italianate houses built between about 1855 and 1864 on land that was divided into lots in 1852. The block includes a cruciform house at 4000 Pine Street, a centre-hall house at 4002, a towered brownstone double house at 4004-06, and several double houses with bracketed cornices and square porch posts. Plasterers, carpenters and builders held the lots during construction, and the designs are associated with the Philadelphia architect Samuel Sloan. The block is valued for its unified streetscape, with its rhythm of openings and shared rear yards. It is also regarded as an example of the suburban house type popularised by Andrew Jackson Downing. Early residents included a Lutheran minister and University of Pennsylvania trustee and a professor of moral and mental science.","period_of_significance":"1853-1863","architect_builder":null,"architectural_style":"Italianate","criteria":[],"status_note":"The nomination states that the houses at 4000, 4002 and 4004-06 Pine Street are in sound condition, and that 405 South 41st Street was demolished in this century.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.593633-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79002321.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79002321/db97ab3776-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79002321/db97ab3776-1600.webp","licence":"Public domain","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Hamilton_Family_Estate_W_Philly.JPG\" rel=\"noopener\">Smallbones</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Hamilton_Family_Estate_W_Philly.JPG"},"district":{"nrhp_refnum":"97001669","name":"West Philadelphia Streetcar Suburb Historic District","url":"https://nationalhistoricalregister.com/districts/pennsylvania/west-philadelphia-streetcar-suburb-historic-district-97001669/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71997200","wikipedia":"https://en.wikipedia.org/wiki/Hamilton_Family_Estate","wikidata":"https://www.wikidata.org/wiki/Q5644927"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/philadelphia/hamilton-family-estate-79002321/"}
