The house dates from 1848 and the barn from circa 1846.","why_significant":"The nomination argues the house is a typical example of a mid-nineteenth-century center hall, ell-plan brick farmhouse of southwestern Pennsylvania, with interior woodwork common to the area. It also argues the house and its outbuildings form a locally important farmstead complex that retains a high degree of integrity.","narrative":"Built of handmade red brick laid in common bond, the two-story house at Mamont Road in Washington Township was begun in 1848 by John Walter, a blacksmith and dairy farmer. It has five bays, end chimneys, a gable roof, and a three-part doorway with a tripartite window above it, with cut stone lintels and original shutters. Its interior includes wide white oak floors, a walnut center hall stair with a continuous curving railing, and carefully detailed trim in the living and dining rooms. A circa 1846 bank barn across the road, dated in relief above one opening, was used for Walter's dairy. The nomination regards the house as a typical example of center hall, ell-plan brick farmhouses built in the region before the Civil War. It is also valued as a locally important farmstead complex, with its 1974 rear porch enclosure and kitchen addition judged sympathetic to the original form.","period_of_significance":"1846-1912","architect_builder":null,"architectural_style":"Greek Revival","criteria":["C"],"status_note":"The house has been in residential use; the barn is separately owned and the land is no longer farmed.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:37.421405-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/95000885.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/95000885/68923dbae6-800.webp","url_1600":"https://nationalhistoricalregister.com/media/95000885/68923dbae6-1600.webp","licence":"CC BY-SA 3.0","author":"Generic1139","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:John_Walter_Farmstead.jpg\" rel=\"noopener\">Generic1139</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:John_Walter_Farmstead.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71995565","wikipedia":"https://en.wikipedia.org/wiki/John_Walter_Farmstead","wikidata":"https://www.wikidata.org/wiki/Q1702097"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/westmoreland-county/walter-john-farmstead-95000885/"}
