 In 1951 a classroom was added to the eastern end of Block C. Plans for the new classroom show it was formed in the sectional school manner by moving the gable end wall and inserting a single-skin partition, with centred double-leaf door, between the existing and new classrooms.The southern wall had casement windows, with fanlights, and the north-facing verandah was extended, with the hat room relocated to the new eastern end.Double-hung sash windows were installed in both the new and existing verandah walls.
