The Brimfield High School building shown here was built in 1936. At least three sets of additions to the building were made during the 1960s. In 1990, a new science lab, weight room, a study hall classroom, and additional student lockers in the hallway were added. Upon the completion of the new BHS facility in summer 2011, the old building was demolished and is now the site of the parking lot/bus drop-off lane for the new building.
