Completed in 1911 for civic leaders Paul and Mahala Hackbarth, this concrete block house is an unusual example of vernacular architecture. Its prominent features include a wraparound porch, Ionic columns on piers, and large wood sash windows. The Hackbarth Lumber Company, one of the earliest businesses in Sealy, promoted the use of concrete blocks for local buildings, and this house is a fine example of that construction method.
