It is a shingle and clapboard building with a 1930 garage.","why_significant":"The house keeps its original design, materials and workmanship, and displays intact Queen Anne details such as a pargetted gable and a terracotta-tiled chimney. It reflects the late-19th-century development of the Stickney subdivision by local businessmen. It is one of few houses in that subdivision remaining in near original condition.","narrative":"Built around 1890, this Queen Anne style house at 21 Dartmouth Street in Somerville sits in an urban neighborhood of late 19th-century single and two-family homes. Its walls are shingle and clapboard, and it has had no major alterations. Notable details include a pargetted gable, a chimney with threaded brickwork and terracotta tiles, and shingles applied to follow the contours of the porch roof. Similar houses at numbers 13, 15, 17, 19 and 23 suggest one builder worked on the street. The house belongs to the Stickney subdivision, platted in 1883 by Rufus Stickney and John Poor, partners in a mustard and spice firm, who intended large lots for businessmen's homes. Deed research suggests it may have been Stickney's own house. Most of the well-detailed houses in the subdivision have been altered, but this is one of only a few that remain near original condition, which supports its local significance for architecture and for the pattern of development.","period_of_significance":null,"architect_builder":null,"architectural_style":"Queen Anne","criteria":["A","C"],"status_note":"Condition described as excellent; in use as a residence with no major alterations.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:01.78046-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/0/7915/63791500/content/electronic-records/rg-079/NPS_MA/89001255.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/89001255/0ebf83e074-800.webp","url_1600":"https://nationalhistoricalregister.com/media/89001255/0ebf83e074-1600.webp","licence":"CC BY-SA 4.0","author":"User:Magicpiano","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:SomervilleMA_HouseAt21DartmouthStreet.jpg\" rel=\"noopener\">User:Magicpiano</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:SomervilleMA_HouseAt21DartmouthStreet.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63791500","wikipedia":"https://en.wikipedia.org/wiki/House_at_21_Dartmouth_Street","wikidata":"https://www.wikidata.org/wiki/Q14715574"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/middlesex-county/house-at-21-dartmouth-street-89001255/"}
