It typifies west Main Street's gradual conversion from residential to commercial use. Its intact condition and scale contribute to Hyannis' character as a summer resort.","narrative":"Built around 1920 on the north side of west Main Street in Hyannis, this small commercial building is a 1 1/2 story wood-frame block with a rear ell and a gable roof. Its Colonial Revival design includes wood shingle siding, a three-part dormer with balustrade, and a facade largely filled with plate glass show windows and recessed entries under a signboard. Side windows have multi-pane lozenge-shaped upper sash, a feature drawn from the earlier Queen Anne style. The building appears little altered and even keeps its original downspouts. It was listed for its role in the gradual shift of west Main Street from houses to shops in the early twentieth century, and for how well it preserves its original character. Though plainly commercial, it respects the scale and materials of neighboring residential buildings and reflects Hyannis' growth as a summer resort.","period_of_significance":null,"architect_builder":null,"architectural_style":"Colonial Revival","criteria":["A","C"],"status_note":"Condition is described as good, with no major alterations; present use is commercial, as was the original use.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:01.841266-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/29/7891/63789129/content/electronic-records/rg-079/NPS_MA/87000286.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/87000286/00bac525fb-800.webp","url_1600":"https://nationalhistoricalregister.com/media/87000286/00bac525fb-1600.webp","licence":"CC BY-SA 2.0","author":"Thomas Kelley from Boston, MA","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Building_at_600_Main_Street.jpg\" rel=\"noopener\">Thomas Kelley from Boston, MA</a>, <a href=\"https://creativecommons.org/licenses/by-sa/2.0\" rel=\"license noopener\">CC BY-SA 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Building_at_600_Main_Street.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63789129","wikipedia":"https://en.wikipedia.org/wiki/Building_at_600_Main_Street","wikidata":"https://www.wikidata.org/wiki/Q4986577"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/barnstable-county/building-at-600-main-street-87000286/"}
