Le Grand-Espace is a landmark performing arts venue dedicated to youth-oriented productions. Its coloured glazed façade connects the performance space to the city while filling the double-height lobby with filtered red light. Red walls, black ceilings, and varnished plywood create an immersive and welcoming environment. Signage, developed in dialogue with the building’s volumes and colour palette, reinforces the project’s identity. A flexible black box theatre with retractable seating supports diverse artistic projects and intimate relationships between performers and audiences.
