Square One Mall is a key part of Mississauga’s city centre. Located adjacent to City Hall and the Living Arts Centre, the shopping centre was built in the 1980s with the support of city leadership.
After many years of success, Square One Mall expanded in the late 1990s in order to add entertainment and power centre components. The expansion included a below-grade parking garage and retail component, long span spaces for large retail above-grade, and a block of cinemas with a unique feature entrance.
The building was framed with cast-in-place concrete structure up to grade. Concrete columns brace the long span roof structure, a design decision that maximized the flexibility of retail store sizes and layouts above grade. The cinemas built over the parking garage are supported by a transfer slab system that allowed the placement of columns with relative flexibility.
Challenge: Design an expansion to an existing shopping mall that modernizes the centre and enhances it as a shopping destination.
Solution: The retailers required large column-free spaces to maximize flexibility. The theatres included a large entrance atrium that became the main entrance to the expansion. The theatres are located on several levels over a parking garage, requiring a series of structural transfer systems.
