The main campus of the Universite du Quebec a Montreal (UQAM) was realized in three phases: phase I, the Hubert-Aquin and Judith-Jasmin pavilions (1972-1986); phase II, the Athanase-David building and Therese-Casgrain pavilion (1986-1992); and phase IIA, the Formation des Maitres pavilion (1989-1993).

Achieving a symbiosis between citizen and university was the main (sociological) challenge of this architectural project, which was shaped by the university's policy of openness and desire to harmoniously integrate the neighbourhood. Situated atop the city's busiest transportation hub, the Berri-UQAM station, and located in the heart of the city's core, UQAM is an urban university. Inspired by the underground city at Place Ville-Marie and wanting the local population to use the university's passages, Jodoin Lamarre Pratte architectes developed an underground system of free movement. The result: a vast agora on four storeys that bathes in natural light and that skirts pedestrians. Called a "true-city university," UQAM respects the scale of its environment, preserves fragments of the old Saint-Jacques church (the facade, bell tower, transept and sacristy's woodwork) and encompasses the Chapelle Notre-Dame-de-Lourdes.

Transparency, accessibility, flexibility and mobility characterize UQAM's architectural approach. Phase I buildings, which are entirely covered in brick, a material more modest than greystone, are constructed across two vast lots in a Brutalist language. Phase II buildings, which together form a C around the old Ecole polytechnique, express the more classic logic of facade subdivision but through a postmodernist lens. By opening up spaces to the street, phase II buildings maintain the urban fabric's commercial nature. In phase IIA, a twelve-storey tower juxtaposes glass and brick and accentuates the architectural heritage of the two previous phases.
