 The next major period of expansion for the school in terms of its building stock took place in the 1920s.Major alterations and additions were made to the main building; extensions were built on to the west side of the Dining Room block and at the south end of the Dining Hall; and a new building was constructed with classrooms and other facilities, completing the west side of the courtyard formed by the Dining Hall and the other early 1900s additions.The most significant of these works in terms of the original school were the alterations and additions to the main two-storey stone building carried out in 1924.
