With distinctive design and contemporary convenience, this tranquil estate sits on its own private peninsula in Middle Bay. Situated on 6 private acres in Pennelville in Brunswick, and enjoying over 1,000' of deeded water frontage, this well-appointed 5-bedroom, 3-bath home has over 4,000 square feet from which to enjoy its panoramic views in all four seasons. From the tiled entry way, hardwood floors guide you to a proper living room, complete with fireplace and water views. Step up into the formal dining room, where graceful built-ins maximize space, and where water views continue to pull you through the home to the kitchen, featuring its own dining area, granite countertops, professional appliances, and loads of thoughtful storage. Beyond the Russian stove with reading nook, step down into the family room adjacent to a woodstove heated solarium. From the main floor hall, access the convenience of a first-floor bedroom along with full bath. The architectural stairwell leads you up to three more bedrooms, and one more full bath, as well as a primary suite with its own full bath featuring a whirlpool tub. Window benches throughout the upstairs invite repose as you take in the water views from almost every room, while large windows and skylights throughout keep you connected to the natural beauty outside. The spacious laundry room is conveniently located on the upper floor. An enclosed breezeway connects the home to a large three car garage, with a loft above. Beneath the home sits a large dry basement, with its own high ceilings, finished media room, and a mirrored dance studio, as well as the mechanical systems.
