The building's wooden windows were replaced in 1949 with steel frame windows that duplicated the original design. The auditorium originally occupied the north wing which was remodeled in 1958 to accommodate an additional five classrooms and a teacher's lounge. Metal canopies have been added to the sides of the north wing which did not remove any substantial building fabric.
The classroom block has a central hallway terminating in the doors on the east and west sides. Doorways with transom windows lead to the classrooms on either side as do ventilation windows. This hallway is lined with student lockers.
