“Calhau” at 1681 Ocean Boulevard is a professionally curated coastal residence at the intersection of design, sustainability, and innovation-offering views of Foss Beach, Awcomin Marsh, and Rye Harbor. What sets this home apart is its unique relationship with the surrounding landscape-marsh views unfolding in the backyard and Atlantic Ocean vistas from the front-creating a daily connection to the rhythms of the coast. Spanning 3,786 sq ft, the home blends timeless materials with modern coastal living. A chef's kitchen with custom cabinetry, honed granite, and Italian tile backsplash opens seamlessly to dual living spaces, where walls of glass frame water views. The first-floor primary suite captures peaceful marsh vistas and features a spa-inspired bath, while two additional en-suite bedrooms provide comfort and privacy for guests. Architectural details elevate the experience throughout, including a floating metal staircase, wide-plank white oak flooring, and a thoughtfully integrated interior greenhouse. Expansive 114” Marvin doors create a seamless indoor-outdoor connection to Brazilian wood decks-ideal for enjoying the coastal setting. Built with a forward-thinking approach, Calhau prioritizes performance and efficiency. A 28-panel solar array with battery backup, Platinum LEED certification, and a HERS score of 27 position this home among the most energy-efficient offerings on New Hampshire's Seacoast. Located in the desirable town of Rye, this is a rare opportunity for the eco-conscious buyer or discerning investor seeking a legacy coastal property-where the surrounding landscape becomes an extension of the home, and every detail reflects thoughtful, forward-looking design.
