The outbuildings are presented as unusually elaborate survivals that show a country builder's knowledge of changing Victorian modes. The intact Music Room is cited as a notable interior.","narrative":"Built in brick between 1882 and 1887 for David Grove, this two-story house near Maytown has a full third story set within a mansard roof with a distinctive bell-cast curve, covered in patterned red and gray slate. The brick walls are finished with painted cement wash, and the windows and dormers carry decorative brick hoods and paired sash. The house is regarded as a fine example of the Second Empire style adapted to a country setting, and its massing and detailed woodwork are central to that judgment. The Music Room retains its parquet floors, marbleized slate mantel, gilded mirror and plaster ceiling ornament, and it is described as largely unchanged. Two brick outbuildings, a pony house and a carriage house, add elaborate cupolas and cross gables in a more rustic Victorian idiom. Alterations made in the 1920s, including a solarium and a flat-roofed rear addition, are small in scale and do not obscure the original form. The property was sold at a sheriff's sale in 1887 to Michael R. Hoffman.","period_of_significance":"1882-1887","architect_builder":null,"architectural_style":"Second Empire (country version); outbuildings described as Victorian, with Carpenter Gothic and Stick Style elements","criteria":["C"],"status_note":"Altered: 1920s exterior alterations include a solarium, a flat-roofed brick addition and a Colonial Revival front porch; the mansard roof was re-covered in 1980 with a synthetic membrane.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:33.302276-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/83002251.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/83002251/c121c812ac-800.webp","url_1600":"https://nationalhistoricalregister.com/media/83002251/c121c812ac-1600.webp","licence":"CC0","author":"Jbarta","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Grove_Mansion_(Townsend_Residence).jpg\" rel=\"noopener\">Jbarta</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:Grove_Mansion_(Townsend_Residence).jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996420","wikipedia":"https://en.wikipedia.org/wiki/Grove_Mansion","wikidata":"https://www.wikidata.org/wiki/Q15222189"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lancaster-county/grove-mansion-83002251/"}
