Our People


Tom Bassett Dilley’s passion for architecture was kindled in high school when he found a book in the school library on Frank Lloyd Wright: those exuberant buildings harmonized with their sites were endlessly fascinating and inspiring. Shortly after he found Edward Mazria’s Passive Solar Energy Book, whose practical techniques showed how to tune a building to climate. Tom spent a year at Taliesin West, the Frank Lloyd Wright School of Architecture, continuing to Ball State University for undergrad and Columbia University for graduate work. He became a Certified Passive House Consultant in 2010 to learn advanced energy modeling, building science, and principles of conservation exemplified by the Passive House standard. He is a founding member and past President of the Chicago PHAUS chapter, and has presented numerous times for local audiences and at national conferences. Tom is an avid guitarist, gardener, and painter. He lives in Oak Park with his wife and their two children, cats, and dog.


Denny’s interests lie in crafting spaces that fit naturally within their larger contexts. Denny honed his skills in graduate school at Washington University in St. Louis before moving to Seattle, WA where he spent years designing 21st century educational environments. An avid woodworker and licensed architect, he joined the team in 2018 as a project manager. His attention to detail translates all projects scales. You will find Denny enjoying the outdoors of his Oak Park home where he lives with his wife and two kids.
