 Over its almost forty-year history, Coffman has gone through many additions and upgrades; the most major include the expansion of the B building, which now houses the English, World Languages, and Social Studies departments, and the addition of the A building, which encompasses the library, technology- related classes, Mathematics, and Science departments.In the 2009-2010 school year, Dublin Coffman underwent a series of renovations to the building.These renovations made it possible to add 10 classrooms, seal the outdoor courtyard, add classrooms off of and below the bridge between the A and B buildings, and move the location of the administrative offices and main entrance to the opposite side of the building .
