When built in 1867, the school housed four classrooms, two on the west side of each level, with stairwells, coatrooms, and other facilities on the east side. On the second floor this plan is still in place, with wainscoted plaster walls, blackboards, and original door and window surrounds. On the first floor, the wall between the two classrooms was removed in the 1920s to accommodate town meetings, and a suspended acoustic tile ceiling was added in the 1970s. The cupola is a reconstruction of the original, also made in the 1970s, and houses a bell originally hanging in the South Dennis Graded School.
