Who we are

About Us

Square Root Architecture + Design is an industry recognized leader in high-performance and sustainable building design.

We are committed to architecture that marries building science with design, creating solutions that are both in harmony with the environment and the economic needs of our clients.

We aim to think outside the box. Yes, it's ironic being that "Square" is in our name, but we like to think of it more as a reference to our values, in that we take how we treat people and the world around us seriously.

We tend to be building science geeks who have a keen appreciation for design, and quality over quantity.

We love to implement new technologies within our smartly designed spaces in order to maximize the building's performance, translating to a greener community and a greener wallet for our clients.

At the end of the day, we're here to make a difference using our designs as the catalyst for change.
