Our story is rooted in a love of architecture, design excellence, partnership, collaboration, innovation, entrepreneurship, and community-building.

We have a proud legacy of buildings and places that people cherish and love across Canada, and internationally. Our story begins in the 1950’s with two young architecture firms that would ultimately come together with a shared sense of purpose to make the world a better place.

Our story, and the unique way we work, is in the origin of our name.

At the time few, if any, architectural firms in Canada had a moniker that did not pay homage to a founding practitioner in the firm.  The move away from this was intentional. 

Our founders realized that we are better working under one banner with a common purpose and collective ethos.  The strength of Number TEN became the power of the whole organization and its talented people.  

The new name was inspired by the firm’s address at the time, 10 Donald Street, a unique modernist design by Waisman and Ross.
