At the west end of Osterville’s iconic Sea View Avenue in Wianno, this extraordinary estate is more than a home—it is a masterpiece of craftsmanship and artistry. Set on 1.2 acres of horticultural privacy with glimpses of West Bay, the 7,350 sq. ft. residence showcases hand-built mahogany windows and doors, quartersawn oak floors, curved walls and bespoke cabinetry and moldings—all created with skill from a bygone era. Seven bedrooms in the main house are complemented by a one-bedroom apartment above the three-car garage, complete with radiant floors. Outdoors, a 50-foot gunite pool and stone terrace shaded by Japanese maples invite alfresco dining, while waves on Nantucket Sound echo just across the avenue. Ownership includes rare deeded access to a private Nantucket Sound beach and to Eel River for kayaking and paddle boarding. At 850 Sea View Avenue, every visit reveals new beauty and discoveries making this home a true legacy property. Please verify all information contained herein
