The original section is dated to about 1737 and was built by Joseph Gregg.","why_significant":"The nomination argues the house is a nearly intact example of early eighteenth-century rural Southeast Pennsylvania vernacular Colonial architecture, combining German exterior symmetry with English plan features. It is described as one of a small number of such houses left relatively intact in the Chester and Delaware County region, and as a transitional form between Postmedieval and Georgian design. The Gregg family, who held the house for several generations, is also part of its historical context.","narrative":"Built about 1737 by Joseph Gregg on a rise in rolling farmland south of Kennett Square, this three-bay, symmetrical brick house has a stone foundation, an end-gable roof and Flemish-bond front walls with glazed headers. Its plan combines a symmetrical German-influenced facade with an English hall-and-parlor interior, and the nomination places it within the transition from Postmedieval to Georgian design. The Gregg family, descended from John Gregg, who had acquired the land in 1713, held the house and its 200 acres until 1915, when the land was sold. Kitchen and second-story additions were built around 1820 and 1860, and a 1916 frame addition was later removed. Restoration campaigns in the 1970s and 1980s retained most of the original woodwork, windows and hardware. The house is regarded as one of the few early examples in the region that retains its eighteenth-century interior with little alteration, and it is valued for showing how a prosperous farm family lived.","period_of_significance":"C. 1737 - C. 1860","architect_builder":null,"architectural_style":"COLONIAL (English and German Colonial influences)","criteria":["C"],"status_note":"Continues to be used as a residence; a 1986 addition and restoration campaigns are documented.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:37.615088-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/94000007.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/94000007/836c2711c7-800.webp","url_1600":"https://nationalhistoricalregister.com/media/94000007/836c2711c7-1600.webp","licence":"CC BY-SA 3.0","author":"JERRYE &amp; ROY KLOTZ JR","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:JOSEPH_GREGG_HOUSE.jpg\" rel=\"noopener\">JERRYE &amp;amp; ROY KLOTZ JR</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:JOSEPH_GREGG_HOUSE.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996018","wikipedia":"https://en.wikipedia.org/wiki/Joseph_Gregg_House","wikidata":"https://www.wikidata.org/wiki/Q6283582"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/chester-county/gregg-joseph-house-94000007/"}
