History Description
The Unionville Planing Mill was constructed on the site of the historic planing mill established by William Eakin in 1873. The planing mill produced lumber and millwork to supply Unionville’s building boom that followed the coming of the railway in 1871. In 1881 Eakin sold to local carpenter Robert Harrington. The Harrington family owned the business until 1960, when it was sold to Alfred Giles. The mill was damaged by fire in 1978, and later destroyed by a second fire in 1982. A new commercial building designed to recreate an old mill building, but not copy the Eakin-Harrington planing mill, was constructed on the site in 1986.
