Berthelet Street and the Fraser Institute. The new building on Peel Street had thirty-two classrooms, those in the south wing for girls and in the north wing for boys. The corridors both led to an administrative heart at the centre, with gates topped by iron spikes to separate girls and boys. The site at 1455 Peel Street was later occupied by the Mount Royal Hotel, which in the 1980s was converted into the present-day Les Cours Mont-Royal. In 1911, with the school continuing to expand, a site for a new building was acquired, and in 1914 construction began of the school's final home, at 3449 University Street. The school was able to move in during September 1915.

Both were former pupils of the school.

The many flourishes include four caryatids high above the main entrance and other decorative features, while the design of the staircases is believed to be unique, with separate double flights, one for up and one for down, which do not intersect. The auditorium was wood-panelled. The new building provided over sixty classrooms, on five floors, taking children all the way from first to twelfth grade. The school was the first in Montreal to have its own swimming pool, completed in 1924 in the basement of the new University Street building. There was also a shooting gallery, where sixteen people could shoot at targets 25 yards away, but at first it was used only by the boys, as was a room for sloyd. The library was common ground, but the physics and chemistry laboratories were in the boys' wing. Art was taught in separate rooms, and although the swimming pool was shared, girls and boys used it at different times. At first there was only one gymnasium, for boys, but soon the school's auditorium was converted into a girls' gym and a new auditorium was added behind the H-block. There were
