Chris Green, LLC

36 Sawyer Hill Rd.
New Milford , Connecticut 06776
Phone: (203) 628-0539

A craftsman searching for good designs and artful solutions in residential construction. Since 1987, I have restored old houses, made windows and doors, matched historic millwork, and designed and built kitchens, baths and room additions, while continually raising the bar on my own long-standing interest in energy efficiency.

Influenced early on by Christopher Alexander’s “A Pattern Language,” creating a space that inspires and grows out of the user’s experience is important to me. This, combined with a love of old and new buildings, has made achieving a balance between new designs and existing structures a worthy challenge.

At COA you hold in your own hands the freedom, and responsibility, of building your educational path. Each student designs their own course of study in human ecology—an exploration of the relationships between humans and their natural, cultural, and built environments. Even though we all have the same major, no two students have ever taken the same set of classes. And you don’t have to choose just one area of study; in fact, we hope you’ll pull together different disciplines and get excited about the surprising connections between them.
