Cosán = Pathway  

Cosan Studio was founded on the fundamental belief that life is constantly changing and that design must adapt and change with it to stay relevant. The team at Cosan Studio helps clients along the pathway to understanding and enjoying the benefits of thoughtful, well-designed structures that not only are beautiful, but also have the ability to stir emotions and invoke a reaction. They strongly believe that buildings can and should live lightly upon the surface of this planet we call home.

Adam Kostis has been designing in the valley for the last eight years working alongside Scott Carson and Tom Bell. Adam received his Bachelor's of Architecture from the University of Arizona. Having lived in Arizona for the last 29 years, he holds a strong connection to the Sonoran Desert. One of his favorite design strategies is to use light as a tool for carving space. Adam also believes that architecture should engage the landscape in a meaningful way through distillation, detail, craft, and poetics. All of which are successfully executed with passion, and teamwork. It is the collaborative process that separates Cosan Studio from the rest.
