Andres Stell, LEED®AP
Architectural Designer

Andres is a designer with over 15 years of extensive experience in the design and documentation of higher education, mixed use residential, science & technology, healthcare, religious, education and retail projects.  Andres' expertise in the use of 3-D visualization software such as Revit provides the firm with a tremendous asset towards serving our wide range of clients.

Andres is passionate about all aspects of sustainability. In a world with limited resources, he truly believes we need to think about the way we live and the process towards good design.  One example Andres lives in what he believes is that he has been commuting to work on his bike since 2007, logging on an average of 60 miles a week on his bike.  Aside from biking, Andres’ interests also include photography, gardening and woodworking. He sees photography as a way to capture the beauty and reality of life, in a way that is preserved and can be shared. He enjoys gardening, because he loves knowing that with a little effort, one can grow food from seed, and start to close the loop for the way we live. He tries to use as much as he can from the garden, and then the scraps and waste are composted and returned to the garden to provide nutrients for the next cycle. With woodworking he finds a joy in creating something with his own hands that his family and friends can use. His hobbies influence his career, as he strives to design places that help capture the beauty in life, and are closely tied to balances of nature that one experiences when one gardens.
