“Cabins” is hardly an apt description for this compound consisting of a group of four cottages arrayed on the shore of a pond in central Maine. A singularly unique project, the exquisitely detailed buildings prominently feature Duratherm’s Lift/Roll doors with framless corners and flush stone sills. Tenants can roll the doors open, enabling one entire corner of the Living room to become an extened porch and providing unimpeded access to the front deck and pond beyond.
