Additions to homes in historic districts often require adherence to local guidelines and approval of architectural review boards.  The early 19th century Ratcliffe House is one such--a brick home built into the side of a steep hill.  In the addition we repeated the scale and rhythm of the home, but at a reduced length, width, and height so that it would be subordinate.  We oversized windows to help indicate that the stone addition is modern.  We paid particular attention to window detailing.  We employed stone salvaged from a local, demolished barn to serve as a contrasting, durable, sympathetic material.
