Robert Castle Gay, Architect

Robert Castle Gay • Architect and Principal • The calling toward a career in architecture became clear to Robert at age 8 when he drew his first floor plan. By the age of 12, he had participated in the construction of the family home. Robert engaged in summer programs at Brown University and the Rhode Island School of Design. He received his degree in architecture from the University of California at Berkeley. There he studied with Chris Alexander in the early days of the "Pattern Language." This was followed by three years at the University of Hawaii as an instructor of architecture.

Shortly after the first Earth Day in 1970, Robert changed focus from university teaching to full-time design and building. After a move to the northwest, Robert founded Radius Construction. Two decades of design-build work followed. A strawbale workshop in 1992 confirmed his passion for alternative building materials. In 1996 he hung up his tool belt and moved to Tucson, Arizona where he has been working as a licensed architect focused primarily on the creation of residential environments. "Desert rat" is a term of esteem in his vocabulary.
