It sits on an 8.9-acre lot with a carriage barn, smoke house and cast-iron lamp post.","why_significant":"The nomination argues the house is a distinctive local example of Gothic style embellishment applied to a traditional Greek Revival house form, with Italianate details added. The remodeling is attributed to master builder William Harmon and is linked to the Harmon and DePuy houses. Three intact outbuildings and objects add to its integrity of setting.","narrative":"Set close to busy West Main Street in Lima, this two-story, three-bay frame house began around 1844 as a simple Greek Revival dwelling built for Dr. David Dayton, a local physician and druggist. In the 1850s and 1860s it was upgraded with Tudor Gothic hood molds over the door and windows, broadly overhanging eaves and an ornate Italianate side porch with chamfered posts. The remodeling is attributed to master builder William Harmon, and may have been commissioned by banker John Mosher, who owned the house from 1857 to 1866. Inside, the stair, six-panel doors, molded trim and an Italianate marble mantel survive largely intact. The grounds hold a brick smoke house, a two-story carriage barn and an original cast-iron lamp post. The house is valued as a local example of Gothic detailing applied to a traditional house form, comparable to the Harmon and DePuy houses nearby.","period_of_significance":"ca. 1840s; ca. mid 1850s to ca. 1900","architect_builder":"Architect unknown; builder attributed to David Dayton, alterations attributed to Wm.
