Espace citoyen des Confluents reclaims a 13-acre industrial brownfield as a regenerative civic hub where nature shapes community life.

Through landscape architecture, the project reimagines a former petrochemical site marked by environmental degradation as a five-acre intervention grounded in ecological and social restoration. Located within the Greater Montréal region of Québec, Canada, in a suburban setting, the project addresses two defining challenges: remedying a long-standing lack of local amenities while re-establishing ecological continuity and a shared sense of place.

Renaturalization unfolds as a living system structured by water, which constitutes the project’s landscape infrastructure. A network of interconnected retention basins manages all stormwater on site while fostering resilient biodiversity through native plantings, wildlife corridors, and deliberately retained self-seeded vegetation. More than 300 trees anchor a dynamic ecosystem, offering residents a forested wetland within an established built fabric.

A footbridge and two observation platforms provide access to the basins and the mature trees preserved on site, while birdhouses support wildlife activity. As the seasons unfold, layers of vegetation and microhabitats create a sensory experience that soothes and slows the pace of everyday life.

From the earliest phases, Projet Paysage and architecture firm Cardin Julien combined their expertise to conceive a civic space where architecture and landscape shape one another. The building, designed to exceed LEED v4 Gold certification requirements, asserts a bold angular geometry, balanced by a fluid and organic landscape framework that orchestrates movement and spatial rhythm across the site. Visual openings and outdoor spaces extend the architectural experience.

Here, nature is not ornamental but foundational. Through accessible natural environments, gathering places, and active mobility pathways, Espace citoyen des Confluents shapes social life and identity—positioning the landscape as a catalyst for community well-being and long-term urban vitality.
