Presenting one of Cape Cod's finest waterfront estates, set on the sparkling shores of Cotuit Bay with a substantial deep-water dock, resort-style swimming pool, and stunning water views. The seven-bedroom residence is finished to the highest standards with exquisite craftsmanship and top-of-the-line finishes. Upon entering, an inviting foyer leads to the heart of the home: an eat-in chef's kitchen that opens to a spacious living area equipped with a wet bar. Glass doors and oversized windows line the waterside of the home, seamlessly connecting to a covered stone terrace with radiant heat, electric hurricane shutters and screens, and an outdoor kitchen. Rich millwork, beamed ceilings, and custom built-ins are showcased throughout, from the formal dining room to a well-appointed family room with cathedral ceilings and a stone fireplace. An en suite bedroom completes the main level, while an elevator servicing each floor provides the utmost convenience and accessibility. On the second level, an expansive primary suite boasts two private balconies, two walk-in closets, a sitting room, a sumptuous bathroom, and mesmerizing views of Cotuit Bay. Two additional bedrooms offer refined accommodations, while a self-contained two-bedroom apartment with a kitchen and full bathroom can be accessed at the end of the hall - ideal for multi-generational living or staff. Designed as a thoughtful retreat and workspace, the third level features a study with panoramic views, two balconies, a kitchenette, and a bathroom. The walkout lower level delivers exceptional flexibility with 2,000 square feet of living space, including a game room, recreation room, bedroom, and full bathroom. Outside, the luxurious pool terrace offers the ambience of a private seaside resort with stunning views of the bay and across to Oyster Harbors. Mere steps away, one of Cape Cod's most significant deep-water docks affords endless possibilities for boating, with direct access to Nantucket Sound. A rare offering waiting to be enjoyed, this extraordinary waterfront compound is located minutes from Cotuit Village, Osterville, and everything the area has to offer.
