It measures about 20 by 20 feet.","why_significant":"The nomination argues the cottage embodies the distinctive characteristics of a type and period of construction under Criterion C. It is a small, simplified version of Beacon Hill's grand Federal homes, adapted for artisans and laborers. It is also the last surviving house on a street that once held ten residences, and is widely known as Boston's tiniest house.","narrative":"One Bay Street is a tiny brick Federal cottage in Boston's Bay Village, about 20 feet wide and 20 feet deep, rising two and a half stories. Housewrights and organ builders Benjamin and Joshua Bosworth built it around 1830 on a lot laid out by Ephraim Marsh. It is the only survivor of ten houses once lining Bay Street; the northern block was taken in 1908 for a school. The house reflects the style of Beacon Hill's grand homes at a reduced scale and cost, suited to the working-class residents of the district. Its brick walls, recessed paneled entry and multi-pane windows with louvered blinds remain, and the street retains brick sidewalks and granite curbs from the city's 1868 improvements, when buildings in the area were raised 18 feet. Long called the tiniest house in Boston, it appears in newspaper articles and walking tours. It was recognized for its architecture as a clear example of Bay Village residential building.","period_of_significance":"1830 - 1943","architect_builder":"Benjamin & Joshua Bosworth","architectural_style":"Early Republic: Federal","criteria":["C"],"status_note":"Still used as a single dwelling.
