Perched directly on the dunes of East Sandwich, this striking residence enjoys a sandy beach on Cape Cod Bay as its backyard. Offered fully furnished, the architectural heart of the home is a double-height great room with a wall of glass framing panoramic water views, wide plank oak floors, and a Town & Country gas fireplace. The open-concept layout flows into a gourmet kitchen featuring custom black walnut cabinetry, natural quartz countertops, and professional-grade appliances. The first-floor primary suite provides a spa-like retreat with a hammered nickel soaking tub and Carrara marble, while three additional upstairs bedrooms also feature en suite marble baths. High-end details abound, from the mezzanine's stainless steel cable railings and California Closets to the natural cedar roof with copper flashing. Outside, a sprawling deck with private stairs leads through the dunes to the sand, providing the perfect vantage point to watch the tide cross the iconic Sandwich flats.
