59 Acorn Ln in Deer Isle, sited on 4.2 acres of beautiful waterfront on Long Cove, is a contemporary year round house with 3 bedrooms and 2 baths, built in 2008. Its design is from architect Robert Knight's ''Lucia's Little Houses,'' (#14:Stay Focused). Architect, Peter D'Entremont, and builder, Poole Construction, used Structural Insulated Panels (SIP) panels in the construction to achieve high energy efficiency. The house features an open plan with the kitchen and a soapstone wood stove at the heart of the living space. The living room/dining room windows, skylights, and doors provide water views, light, and air from all directions. A wrap around deck extends indoor-outdoor living with180 degree water views over Long Cove. The master bedroom suite, with sliding glass doors opening to the deck, has a walk-in closet and ensuite bath with accessible shower and double sinks. Two guest rooms share a bath on the other side of the house. A guest cottage at the shore and the second floor of a detached garage provide additional living space. The house was built for energy efficient year round living, heated by a propane boiler with European hot water radiators, wood stoves, and a heat pump that also provides air conditioning in the summer. The spacious walk-out basement is heated by a Modine heater and a wood stove. There is a heated 2 bay garage and a whole house generator. The property has 4.21 acres with over 450 feet of waterfront as measured by the tie-line on the survey. The house is centered on a point of land so the actual length of the shoreline is over 570 feet. The point provides privacy and wide, open water views of Long Cove. This is an ideal waterfront house in move-in condition.
