We are a team of architects, designers, leaders, and change-makers creating meaningful spaces for people and their communities.

We are a team of architects, designers, leaders, and change-makers creating meaningful spaces for people and their communities.

We strive to design spaces that improve the natural environment, create value for the businesses and communities they serve, and improve the lives of the people who use them.

We commit to every design problem with curiosity, invention, and a generous spirit to uncover hidden opportunity. It is by embracing the constraints that push us to innovate that we create sustainable, meaningful spaces.

True to our Montreal roots, we promote diversity and openness across our offices and  partnerships. Our team offers the expertise of a global design firm with an unapologetic dose of hospitality; for us, design is personal.
