Presenting a rare and extraordinary opportunity set along the shores of Osterville's exclusive West Bay. This exquisite waterfront estate features a four-bedroom main residence masterfully designed by Hutker Architects to showcase sweeping water views amidst inimitable quality and craftsmanship. Designed as a generational compound affording the utmost privacy in an incomparable setting, the estate includes a three-bedroom guest house, a swimming pool, sandy beach, an outhaul mooring, and a dock for non-motorized crafts. From the poolside terrace to multiple stone patios overlooking West Bay, the property caters to outdoor living and enjoys a seamless connection to its surroundings, with grounds designed by award-winning landscape architect Kris Horiuchi. Throughout the main living space, oversized windows frame breathtaking water views, while understated elegance defines the interiors, with beamed ceilings, wainscoting, and a double-sided stone fireplace that offers striking visual appeal. The chef's kitchen features professional-grade appliances, a breakfast bar, and pantry, equipped for any occasion with an adjacent dining room and direct access to a stone terrace for al fresco dining. Set within its own wing, the first-floor primary suite features a covered deck, a large walk-in closet, a private office, and a luxurious bathroom with dual vanities. On the second level, three bedrooms and two full bathrooms provide well-appointed accommodations for family and guests. Located on Osterville's coveted Eel River Road, this magnificent waterfront estate is minutes from Wianno, Oyster Harbors, and the boutique shops and restaurants on Main Street. Every element of this property reflects intentional design, discretion, and timeless elegance, while embodying the essence of Cape Cod living.
