Perma-Log Company
1940s. 2246 S. Mount Tom Rd., 2.5 miles south of Mio

William W. Maier (1899–1966) developed a technique for siding the exterior walls of buildings with concrete shaped in the form of logs. This sheathing is applied to a steel mesh base anchored by nails to the walls. His house and office display this Perma-log construction. The exterior walls of the one-story ranch are covered with the ersatz material, and the chimneys are sculpted to resemble tree trunks. In the 1920s Maier came from Ontario to Detroit, where he learned lathing and plastering. At 12063 St. Mary's Street in Detroit, he built for himself his first concrete log house. Maier moved to Mio in 1940 and developed the Perma-log business. His grandson, William E. Maier Jr., continues to install Perma-log throughout the state, especially in the northeastern Lower Peninsula. Perma-Log Company advertises the rustic finish as “a stucco log siding that lasts a lifetime . . . done by custom hand work.”
