About Us

We were established in 2009 because we believe that humanity can create a flourishing future for itself and we believe that this future begins with designing our built environment so that it facilitates and enables that future to emerge. 

We are in a climate crisis, and we are losing aspects of ourselves when a remote tribe no longer knows its own language, when the last White Rhino dies, or when a plant goes extinct in a remote jungle that would have cured a type of disease or cancer. There is nothing that inspires us to do our work more than seeing life on this Earth, our only home, flourish—whether it is a Maasai Warrior that is enabled to continue their traditions, or an established old growth forest that will continue evolving forever.

Our clients are Architects, Designers, and Organizations that are working in the built environment. We are the creators of Reveal It assessment tool and we are the cocreators of Biologically Integrated Architecture.

We are called, “Affecting Change” because you are doing the change and we are well known for our ability to help people see the opportunity for making different decisions on their projects.

We help organizations create facilities that are more effective at achieving their mission and purpose while conscientiously redesigning their environmental impact. Our projects are located across Canada, in the Philippines, in the U.S. and in the Middle East and they have won over 60 awards.

Hire us to find out how you can create the change that you want to see in the world.
