It was built in 1835 and sits on a parcel of less than one-half acre with a contributing stone wash house.","why_significant":"The nomination argues the house is a Federal-influenced vernacular example of Pennsylvania architecture with well-preserved interior woodwork, fan-lit entrances and an integral rear ell. It also says the house reflects the social standing of William Schall, an iron master, in the 19th century.","narrative":"Built in 1835 of two-foot-thick fieldstone, the two-and-one-half story house at Green Lane was constructed for iron master William Schall and his wife Caroline. Its rear kitchen ell is part of the original 1835 construction, and the center-hall plan, six-over-six sash windows and Greek Revival moldings are largely original. Two entrances carry fan lights, and the interior retains fireplace mantels, original Dutch locks, and pine flooring. A stone wash house with a walk-in fireplace stands on the same parcel. The house was regarded as a well-preserved example of the Federal style in Montgomery County and as a reflection of the status of its first owner. Its interior woodwork and entrance detailing were considered of unusually high quality when compared with other local Federal houses.","period_of_significance":"1835","architect_builder":null,"architectural_style":"Federal","criteria":["C"],"status_note":"The house is in good condition and remains a residence; the wash house has never been altered and the plaster was removed from the exterior in 1986.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:10:27.148445-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/07001079.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/07001079/0fa4a2a4e4-800.webp","url_1600":"https://nationalhistoricalregister.com/media/07001079/0fa4a2a4e4-1600.webp","licence":"CC0","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Schall_House_Green_Lane_PA.jpg\" rel=\"noopener\">Smallbones</a>, <a href=\"http://creativecommons.org/publicdomain/zero/1.0/deed.en\" rel=\"license noopener\">CC0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Schall_House_Green_Lane_PA.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71995693","wikipedia":"https://en.wikipedia.org/wiki/William_and_Caroline_Schall_House","wikidata":"https://www.wikidata.org/wiki/Q8020720"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/montgomery-county/schall-william-and-caroline-house-07001079/"}
