It sits on the south side of the east end of the Main Street commercial area.","why_significant":"The nomination argues the building is significant for its association with the development of Hyannis' Main Street commercial area. It also values the building as a well preserved, detailed early 20th century commercial block. Its largely original storefronts and its role in Hyannis's character as a summer resort are emphasized.","narrative":"Built around 1910, this large freestanding commercial block at 237-239 Main Street in Hyannis rises two stories on a wood frame under a flat roof with a narrow bracketed cornice. Paired second-story windows hold one-over-one sash, and some have triangular pediments typical of the Queen Anne style. A window at the angled northwest corner is topped by a clock and may once have had a turret. The storefronts appear largely original, with a single recessed center entry and a leaded glass transom. The building is judged one of the handsomest wood-frame commercial blocks in the area. It represents the transformation of Main Street into a busy commercial district in the twentieth century, and its survival with intact storefronts adds to Hyannis's character as a summer resort. It was recognized for its link to the street's commercial development and for its architecture. It remains in commercial use and in excellent condition.","period_of_significance":null,"architect_builder":null,"architectural_style":"Queen Anne","criteria":["A","C"],"status_note":"Condition is listed as excellent; present use is commercial, the same as the original use.
