The core dates to circa 1751, with a main block of about 1820 and a 1935 Colonial Revival renovation by local builder Stanley Yeager.","why_significant":"The nomination argues the house is a representative example of Colonial and Federal style farmhouses in the Saucon Valley that were modernized in the Colonial Revival style in the early to mid-20th century. It is locally significant under Criterion C for architecture, with the 1934-1935 renovation and its catalog-derived woodwork and details central to the argument. The property also has early associations with settler Michael Heller and the Hellerton name.","narrative":"Stone farmhouse on a wooded slope above Saucon Creek in Lower Saucon Township, Northampton County, with a core built around 1751 and a main block of about 1820. In 1934-1935 local builder Stanley Yeager remodeled it in the Colonial Revival style, adding a slate roof with snow guards, a half-oval fanlight, a Doric portico, stone jack arches, and a stair closely matching a Curtis Woodwork catalog plate. The house is regarded as a representative example of older Colonial and Federal farmhouses in the Saucon Valley that were updated in this manner during the early to mid-twentieth century. Its significance rests on that renovation and on the catalog-derived woodwork and interior changes that it preserves. The property also stands on land settled by Michael Heller, who named his tract Hellerton in 1783. A nearby Widow's House, built in 1850, and a root cellar remain on the site. The property is now a historic house museum and township park.","period_of_significance":"C. 1751-1935","architect_builder":"Stanley Yeager (builder)","architectural_style":"Colonial Revival","criteria":["C"],"status_note":"Owned by Lower Saucon Township and operated as a house museum and township park, with the Saucon Valley Conservancy leasing it.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:10:27.071344-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/10000399.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/10000399/c038516f53-800.webp","url_1600":"https://nationalhistoricalregister.com/media/10000399/c038516f53-1600.webp","licence":"CC BY-SA 3.0","author":"Coemgenus","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Heller_House.JPG\" rel=\"noopener\">Coemgenus</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:Heller_House.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996341","wikipedia":"https://en.wikipedia.org/wiki/Michael_and_Margaret_Heller_House","wikidata":"https://www.wikidata.org/wiki/Q15253313"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/northampton-county/heller-michael-and-margaret-house-10000399/"}
