Towards the end of 2015 the school undertook the demolition of Arnold Hall (to be replaced by the Centre for Business & Social Enterprise). The new building was opened in March 2017 by The Hon. Josh Frydenberg, Federal Member for Kooyong, and includes eight classrooms as well as a lecture hall. In 2017, the Junior School introduced the International Baccalaureate Primary Years Programme (PYP). The school also introduced Cambridge University's International General Certificate of Secondary Education (IGCSE) in Years 9 and 10 English.
