Over the years, additions were made to the campus, including the addition of a gymnasium to Rogers House. In 1930, a new residential building which also included two classrooms was built and dedicated to former principal William Firth as Firth House, further adding to the school's capacity for boarding students. Further additions included a running track, four playing fields, and an ice rink. A new dining hall was added in the 1960s. A new student lounge was constructed adjacent to the concourse between Rogers house and the dining hall. A health center is located in New House, staffed by a school nurse, who is on call 24 hours a day for the needs of boarding students.
