luxury seaside houses for sale Knox County, United States

Escape to the beauty and quiet of Matinicus Island. Situated more than 20 miles off the coast of Midcoast Maine, this private 20-acre oceanfront compound includes a year-round main house and a seasonal guest cottage, all set along 1,000 feet of bold shoreline. The main home, built in 1993, blends modern comforts with restored antique charm. A bright kitchen features honed slate countertops, an eat-in island, oak cabinetry, and tile flooring. A Crawford cookstove anchors the dining room with red oak wainscoting, while the back parlor showcases a wood-burning fireplace with its original mantel. The living room includes a built-in TV hutch and access to a formal entry highlighted by a curved ceiling and classic black-and-white tile flooring. The tongue-and-groove ceiling continues upstairs, where four bedrooms reflect thoughtful period details, including a primary bedroom with water views and a guest room with a boat-inspired daybed. A full bath with separate tub and shower, along with a half bath, complete the upper level. Oak flooring runs throughout much of the home. The seasonal guest cottage, completed in 2024, captures expansive ocean views from its oceanside deck. Inside, it features two bedrooms, two full baths, a full kitchen, dining area, living room, and a built-in daybed tucked beneath the stairs. An outdoor shower and rolling lawn lead to the dramatic shoreline and a firepit with sweeping northwestern ocean views, ideal for taking in unforgettable sunsets. Attached and freestanding barns, a garden shed, and a small pond complete this exceptional island retreat.

The Tidewater sits at the head of Carver's Harbor on Vinalhaven island, looking due south over the world's second largest lobster fishing fleet and the open sea beyond. It comprises three conjoined structures, including a three story renovated historic grist mill. Most of the 19 guest rooms enjoy fantastic ocean views and decks overhanging the water. Guests are lulled to sleep by the extraordinary sound of tidal waters rushing through the mill race, beside and beneath the main structure, connecting Carver's Harbor and Carver's Pond. One could operate the Tidewater as it is currently designed or easily convert the former mill building (currently 6 units) into an extraordinary private residence along with the 13 original guest rooms. Vinalhaven is an idyllic Maine experience, and the island makes for the perfect getaway for coastal exploration!
