We are a team of architects that offer personalized professional services.

A better-built environment starts with the curiosity to build. 

As a specialized Ottawa architecture firm, we know that a better-built environment relies on innovative design that puts people first. We achieve design excellence by balancing creative architectural solutions with the practical aspects of creating functional, durable, beautiful buildings.

At Architects DCA, we are local architects with a big vision for the National Capital region, the Ottawa Valley, and Ontario as a whole. We are working toward building a more livable, sustainable city through the design of residential and commercial architecture.
