Expansion of the headquarters of the Confédération des syndicats nationaux (CSN)


The CSN is one of the largest unions in Quebec. The new head office will double the size of the existing building, bringing together all employees in the Montreal area. We have been mandated to create an agora to mark and celebrate the organization’s 100th anniversary.

The agora will be connected to the outdoor by an impressive atrium which opens on the outside. The project includes a grassy slope, a monumental staircase, contemplative spaces, a community garden, a planted lawn and an integrated delivery area.

The project is aiming for a LEED certification.
