I believe this house was built by William Benjamin Mason (1852-1913), a dry goods merchant in Homer, who came to Banks County from Pickens County, South Carolina, as a young man. I’ve seen it referred to as the Moss Mason House, as well; this could be due to the fact that a son of William Benjamin Mason, Dick Moss Mason (1878-1964) was a longtime resident here. The Plantation Plain architecture, popular in rural Georgia in the antebellum era, was also common in the decade after the Civil War and would suggest a likely construction date in the 1870s.
This house seems to be in danger of being lost without stabilization. I originally thought the outbuilding pictured below to be a dovecote, but now I am not sure what purpose it served.
