Its tall proportions and tall windows are cited as signs of a mid-century shift in taste from the classical toward the picturesque. It was also reportedly the second house in Zanesville wired for electricity, about 1904, and it is tied to the Blocksom family and their Union Foundry.","narrative":"Built between 1848 and 1850 for George Washington Blocksom, this brick house at 960 Eastman Street sits on a side hill above downtown Zanesville. It has common-bond brick walls, a rusticated ashlar foundation, tall six-over-six windows, and an oak doorway with sidelights and etched red glass transom. Inside are eight rooms, a sunroom, five remaining fireplaces, and cast iron fireplace facings showing Mazeppa, made at the family's Union Foundry. A stone springhouse survives on the grounds. Two early one-story additions were made at the rear, and asbestos covering later hid the original brick and stone. The house is valued as an example of the period between Greek Revival and Italianate design, with tall proportions marking a move toward the picturesque. It was reportedly the second Zanesville house wired for electricity, around 1904. Blocksom descendants owned it until 1972, when it left the family for the first time.","period_of_significance":null,"architect_builder":"George Washington Blocksom (built for/by)","architectural_style":"Transitional between Greek Revival and Italianate","criteria":[],"status_note":"Described as in good condition and altered; the entire house is coated in asbestos covering that the then-owners planned to remove in an exterior restoration.
