In 1995, the School's centenary year, the Philip Harris Sports Centre was built to support an extensive range of sporting activities. It is supplemented by outdoor facilities at Windsor Park and a rowing centre at Breakfast Creek, enabling students to participate in a wide range of sporting activities. Cultural pursuits have always been an integral part of life at St Margaret’s. An art room and music block were among the first buildings constructed in the 1930s, thanks to a bequest from the estate of John Darnell, and in 2003 a new Arts Centre was built to further foster students’ creative talents in the visual and performing arts. This Arts Centre supports the school's visual and performing arts program with facilities including three art studios, pottery area, and a display gallery.
