Blanchette archi.design has created the Bistro Siège Social and Café Social in Longueuil, Canada. These two venues are located on the ground floor of an office tower at 1111 Saint-Charles Street West.
As part of the project, Blanchette archi.design transformed the existing postmodern lobby into a 2,300-square-foot hybrid space that combines café service, bistro dining, and social gathering areas. Inside, the interior draws inspiration from the architectural codes of the 1960s and 1970s corporate environments.
The Café Social sits in continuity with the common corridor as a lively transitional space bustling throughout the day, while the Bistro Siège Social opens generously onto a terrace and forecourt. The café incorporates travertine, mustard tones, and dark wood finishes, while the bistro adopts an enveloping palette of terracotta, deep greens, light wood, and integrated vegetation, with a dim-to-warm lighting system integrated into the bistro’s ceiling that allows the atmosphere to evolve from morning to evening.
