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 raising the bar on my 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.
