In April 2011, IHA began the building of a small addition to the school to be located on the southern end of the building (left side when looking at the main entrance from Van Emburgh Avenue.) The addition consisted of four new classrooms at the end of the first (ground) and second levels, as well as a new art studio located on the lowest level of the school, where the school's cafeteria is located. The Vincent Herold Fitness Center was also completed, replacing where the old school store was located, on the cafeteria level. The school's former art room, located on the main floor across from the Sisters' Chapel, was renovated into office space for the school staff and administration.
