To deal with fast-growing demand and to avoid cohabitation between these two groups with their often conflicting requirements, it was decided in the late 2000's to expand the school, which had become too small. The location of the new annex was chosen to give children from both school groups direct access to the gym, which separates the elementary and high school sectors. Access to the library and to the other places serving all students is provided by an indoor corridor alongside the gym.
The 14,370 sq. ft. expansion, built on piles, includes the teachers’ room, two spaces for pre-school groups, seven classrooms for the elementary level and a multipurpose space opening onto the new entranceway. This space is also used as a gathering place or an additional classroom when closed in. The architects’ mandate also included rearranging the offices and renovation of an adjacent pavilion used for adult education.
