''Ironbound'' sits on 2.9 acres with 222 ft of shore frontage, providing a premium front row seat to the magnificent views provided by MDI's Champlain and Cadillac mtns, as well as the various islands, waters, and lighthouses of Frenchman Bay. In the foreground lies the home's namesake, Ironbound Island. This rugged island boasts high vertical granite cliffs and outcroppings where often one can find waves crashing like geysers high onto the cliffs. Perfectly complementing these magnificent views are the main house and a guest carriage house, both beautifully designed and custom built with high-quality materials. The main house features 4+ BR's, 3 full baths, 2 half baths, a first-floor kitchen and dining area with spectacular views, and a second-floor great room with a sunroom offering incredible, elevated views of the bay, islands, and mountains. The main residence also boasts a full walk-out basement complete with a 6-person Finlandia all-cedar sauna and plenty of room for additional living space. A detached carriage house provides a heated 2-car garage with a third unheated bay, plus a second-floor guest suite with a full kitchen, bath, vaulted ceilings, multiple skylights, and the same mesmerizing views as the main house. Both buildings were designed for energy efficiency and to take advantage of the sun's warmth, with ceramic and slate tiling and multi-zone radiant floor heating. Premium oak flooring, fir trim, Loewen double-pane windows with clear fir interiors and maintenance-free aluminum exteriors, low-VOC finishes, and two masterfully built wood-burning stone fireplaces add to the warmth of this property. Winter Harbor, an idyllic coastal town offering art galleries, restaurants, and quaint shops, is located just east of MDI, close to the Schoodic division of Acadia National that provides a variety of outdoor activities. During the summer months, water taxi services provide daily picturesque trips across the bay to Bar Harbor.
