Built c. 1860, it is the only known house to have foundations and wall exteriors fashioned entirely out of slate. It was built by the Brownville and Piscataquis Slate Company, a local quarrying operation, for its superintendent, and is believed to be unique within New England for the use of material and level of Italianate styling it presents.
