 This extension was connected to the old building via overhead walkways, and due to it being constructed around a central courtyard, quickly gained the name of the 'doughnut' block.The appearance of the school changed little over the next two decades, however that was changed in 1988.Canterbury had been campaigning for a multipurpose hall for many years, and so there was much disappointment when a major refurbishing program for the original building and the provision of another classroom block did not include a school hall.
