Espace citoyen des Confluents breathes new life into a former industrial brownfield, transforming it into a regenerative civic hub where nature sustainably shapes community life. Through landscape architecture, the project advances a paradigm shift by reimagining a large-scale site – once occupied by a petrochemical plant and shaped by significant ecological degradation – through an approach grounded in ecological and social restoration. Located in Laval, it addresses two defining challenges: remedying a long-standing lack of local amenities while re-establishing the site’s ecological and social value and a strong sense of place after decades of industrial use. Water forms the backbone of the design. A network of interconnected retention basins manages 100% of the stormwater on site while fostering the emergence of resilient biodiversity. More than 300 trees, wildlife corridors and intentionally preserved spontaneous vegetation create a dynamic ecosystem, offering residents the rare experience of a forest-like green space within an established urban context. Here, nature is not ornamental. It is a living framework that shapes uses, social relations and a shared sense of belonging.
