Welcome to Hamilton Way, where timeless coastal design meets modern luxury on the shores of Casco Bay. Tucked at the end of a quiet private road on Cousins Island, this exceptional waterfront property offers over 5,500 square feet of finely finished living space, designed for year-round comfort and effortless entertaining. Completed in 2022, the shingle-style main residence blends classic New England architecture with a clean, contemporary interior. Inside, high-end finishes and understated woodwork create a serene, light-filled environment. The heart of the home is a soaring great room anchored by a stately granite wood-burning fireplace, also visible from a cozy loft above. A chef's kitchen, generous dining area, and seamless indoor/outdoor flow define the main level. Enjoy sunsets from the three-season porch with its own stone fireplace, or step out onto the deck overlooking the water. With 4 bedrooms and 5 full baths spread across three levels, the layout offers flexibility and privacy for both everyday living and hosting. Westerly views across Casco Bay fill many rooms with golden light, and the shared deepwater dock accommodates boats of varying sizes, inviting days on the water. The home is sited on 1.4± beautifully landscaped acres with custom hardscaping, a sizable outdoor entertaining area, and a guest ''Artist Cottage'' with 3 bedrooms and 2 baths ideal for extended family or visitors. An oversized two-car garage completes the offering. Just minutes from Yarmouth Village and 25 minutes to downtown Portland, Cousins Island offers the rare combination of island tranquility with connected convenience. Enjoy nearby sandy beaches, top-ranked schools, a vibrant community, and an unmatched quality of life on the Southern Maine coast.
