Perched above the waters of Penobscot Bay in the Harborside community, this architecturally designed contemporary offers an extraordinary blend of modern comfort and panoramic coastal beauty. Thoughtfully renovated during the current ownership, the main residence has been transformed to maximize its breathtaking southeastern views, while a stunning post-and-beam barn-style guest house has been completed to create an exceptional multi-generational or guest retreat. Upon entering the main home, you are immediately captivated by sweeping views of Penobscot Bay and its picturesque islands. The open-concept design is centered around a beautifully renovated gourmet kitchen, creating the perfect gathering space for family and friends. The adjoining dining area, warmed by a propane fireplace, frames the ever-changing coastal landscape through expansive windows. The spacious living room features all-new windows that flood the home with natural light while showcasing the spectacular water views and providing direct access to a spacious deck. Just beyond, the inviting library offers a second propane fireplace and its own private deck, creating a peaceful space to relax and enjoy the scenery. The first-floor primary suite is a true sanctuary, complete with a generous walk-in closet, spa-inspired bath with an oversized tiled shower, and a private balcony overlooking the bay--the perfect setting to enjoy your morning coffee as the sun rises over the water. An elevator or staircase leads to the second level, where an airy bedroom suite features vaulted ceilings, a propane fireplace, and its own private balcony with commanding coastal views. The lower level is designed for relaxation and recreation, by an indoor swimming pool, an additional bedroom with propane fireplace, a full bath, laundry area, and direct access to the oversized two car garage.
