Set within Quartier DIX30 in Brossard, Canada's second-largest mixed-use shopping centre, Avenue des Lumières has undergone a fundamental rethinking of its role within the urban fabric. Where 11,000 m² of asphalt once prioritized vehicles along a 400-metre commercial strip, a generous landscaped promenade now invites visitors to slow down, explore, and inhabit the space across all seasons.
The technical ambition of the project is considerable: nearly half the site sits above an existing underground parking structure whose slab required reinforcement and waterproofing before any planting could take root. Through a system of raised landforms and integrated planters, the design achieves the soil depth necessary to sustain over 15,000 plants, building long-term ecological value into what was previously an impervious surface.
The design articulates two distinct ways of moving through the site. Along the building facades, a paved walkway offers a clear and efficient path connecting retail destinations. Parallel to it, a meandering trail winds through layered planting beds, offering a quieter, more contemplative experience closer to that of a neighbourhood park. Integrated rain gardens covering 680 m² manage stormwater ecologically, while pergolas, seating areas, a playground, and programmable plazas expand the site's uses well beyond shopping. A pedestrian link to the adjacent REM station positions Avenue des Lumières as a genuine transit-connected urban destination.
