Built on a 13-acre site that once housed a petrochemical plant, the Espace citoyen des Confluents embodies a trueurban, social, and environmental renaissance. Located in the heart of a rapidly changing residential neighborhood, itmeets an essential need for public infrastructure in the neighborhood by providing the community with a library,meeting spaces, a multifunctional auditorium, and a police station. By breathing new life into a brownfield, theproject offers a model of sustainable and exemplary regeneration that transforms a former contaminated site into atrue civic living space.

Architecture in dialogue with its environment
The project's architecture is shaped by a dialogue between the program and the site's energy potential. Thebuilding's placement on a large, undeveloped site allowed for optimizing its orientation along an east-west axis,thereby maximizing its bioclimatic efficiency. Its elongated and oriented volume promotes passive solar gains byprioritizing surfaces exposed to the south, while reducing direct thermal gains on the east and west facades.

Guided by the sun's trajectory, the openings are carefully positioned and punctuated with sunshades, promotingoptimal intake of natural light while limiting overheating in the summer. This interplay of shadows and texturesevolves with the hours and the seasons, enriching the visual experience of the building.
Integration into the site is central to the architectural approach. With its linear and slightly angular volume, thebuilding becomes a structuring landmark in the landscape. The materiality, in natural shades, reinforces thisdialogue: the gray and beige brickwork on the ground floor lightens the volume and anchors the project, while thesecond floor, clad in darker shades of zinc, acts as a contemporary architectural signal rooted in its environment.
The Espace citoyen des Confluents embodies an exemplary approach to sustainable architecture, rooted in carefulconsideration of local climatic conditions, site context and long-term uses. All design decisions were made to achieveexemplary performance standards, which go well beyond the goal of LEED v4 Gold certification. The integration ofpassive and active energy strategies into the architecture is a central component of the project's identity.
A place for meeting and discovery
The project's design is also based on a strong desire to encourage citizens to take ownership of the space. Inspiredby the values of inclusion and conviviality, the project moves away from traditional institutional models to offer atrue third place: an open, flexible, and democratic public space. The program is organized around a large entrancehall that opens onto the north and south outdoor spaces. This bright center acts as a spatial and social hub,providing intuitive connections to the library, community rooms, performance hall, and outdoor spaces.
The organization of the spaces on two levels allows for a natural hierarchy of uses: areas for concentration and quietare located on the upper floor, while the ground floor is designed for meetings and activities. The building proposesseveral modular spaces, that can be adapted for various uses and group events. A range of varied, moveablefurniture facilitates rearrangement, thus further contributing to the site's versatility. The wooden decking of the roofand the natural light accompany visitors as they move around, creating a warm and soothing atmosphere.
A landscape in transformation
The landscape design transforms this industrialized site into a living, rich, and resilient ecosystem. Retention basinsintegrated into the design ensure ecological rainwater management. The reuse of excavated material shapes newreliefs, improving permeability and biodiversity. A dense canopy of vegetation helps reduce heat islands, while aneducational arboretum showcases local species and raises visitors' awareness of ecological dynamics.
More than just environmental restoration, the landscape redefines the citizen experience. The outdoor spaces havebeen designed to host community gatherings, cultural events and leisure activities. Re-naturalized areas andbiological corridors not only promote biodiversity, they also create a welcoming landscape setting that makes forpleasant walks and inspires contemplation.
Mobility and universal accessibility: a project designed for everyone
In a suburban context where the car remains the primary mode of transportation, the Espace citoyen desConfluents takes an ambitious approach to rebalancing mobility and promoting universal accessibility. Designed asa multimodal hub, the site encourages harmonious coexistence between pedestrians, cyclists, and motorists, whilefacilitating access to public transportation. Bike paths connected to the Laval network, bike parking, and securepedestrian access make daily commutes easier.
The entire project incorporates the principles of universal accessibility: adapted pathways, clear signage, and fluidtraffic flow ensure a barrier-free and easily accessible environment for all, including people with reduced mobility.
