Herman Wohlsen is named as builder, and the architect is listed as unknown.","why_significant":"The nomination argues the building is the best local example of the Chicago Style in Lancaster City and County, and that its brownstone doorways are a rare local example of Art Nouveau influence on architectural ornament. It also claims it was the first building in the city or county built specifically as an apartment house, and that it helped shift fashionable residential life on North Duke Street.","narrative":"Three-story brick apartment building on the southeast corner of North Duke and East Walnut Streets in Lancaster, completed in 1909 with thirty-three apartments. Pressed red brick and brownstone trim define its facades, with a tall central embayment, curved bay windows, and a chevron-patterned parapet. Five pedimented brownstone doorways carry carved leafage and incised scrolls, which the nomination regards as a rare local example of Art Nouveau influence in stone. The builder was Herman Wohlsen, founder of a firm later recognized as the county's oldest construction company under one family name. The building is significant for its Chicago Style design and its ornament, and because it was reportedly the first structure in the city or county built specifically as an apartment house. It also marked a shift in North Duke Street from a fashionable residential address toward conversions and new apartments. Interior features such as original tile floors, chestnut staircases and skylights survive.","period_of_significance":"1906-1909","architect_builder":"Herman Wohlsen (builder)","architectural_style":"Chicago Style (also called Commercial Style); Art Nouveau influence in carved ornament","criteria":[],"status_note":"Unaltered exterior and original interior features remain in very intact condition.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:34.440483-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/84003430.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/84003430/d2090d7579-800.webp","url_1600":"https://nationalhistoricalregister.com/media/84003430/d2090d7579-1600.webp","licence":"Public domain","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Hamilton_Apts.JPG\" rel=\"noopener\">Smallbones</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Hamilton_Apts.JPG"},"district":{"nrhp_refnum":"01000956","name":"Lancaster City Historic District","url":"https://nationalhistoricalregister.com/districts/pennsylvania/lancaster-city-historic-district-01000956/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996117","wikipedia":"https://en.wikipedia.org/wiki/Hamilton_Apartments_(Lancaster,_Pennsylvania)","wikidata":"https://www.wikidata.org/wiki/Q5644838"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lancaster-county/hamilton-apartments-84003430/"}
