    High-end finishesShingle-style residenceOpen lawns for gatheringAbundant natural lightSoaring ceilingsDeepwater dockMature woodlands to explore
    Encompassed by more than one mile of shoreline along Casco Bay, Dingley Island is an extraordinary coastal estate with 27± acres, a shingle-style residence, deepwater dock, and exceptional privacy. With open lawns for gathering, mature woodlands to explore, and secluded stretches of rugged shoreline, the property's diverse landscape & immense privacy create a timeless setting & true sense of exclusivity along the coveted Maine coast. Set on the point of the peninsula, the main residence faces east, west, and south, beautifully capturing panoramic water views from sunrise to sunset. The shingle-style home is distinguished by its architecture, fine craftsmanship, and effortless connection between its living spaces & the surrounding landscape. The well-appointed home features 6 bedrooms, 5.5 baths, and 5,805± SF of living space with soaring ceilings, high-end finishes, and abundant natural light. An impressive double-sided Maine granite fireplace anchors the dining & living rooms, creating warm & inviting spaces suitable for quiet moments, intimate gatherings, and entertaining. A separate garage with a 948± SF, 1-bedroom, 1-bath apartment provides added space for guests. Throughout the grounds, exceptional stonework—including walls, grass-lined steps, and several patios—creates a natural progression of outdoor spaces, each thoughtfully designed for dining, enjoyment, and being immersed in the waterfront setting. A private tennis court invites recreation, while a custom-built treehouse adds whimsy & adventure. Down at the shore, the deepwater dock is safely tucked away on a protected cove, creating a serene vantage point to view local lobster boats working the bay. A true wildlife paradise, enjoy seal colonies sunbathing on nearby rock ledges, daily sightings of bald eagles & porpoises, and an array of migrating seabirds moving through the pristine landscape. More than a coastal residence, Dingley Island is a legacy estate designed to be enjoyed for generations.
