Discover this timeless residence perched above Onset Harbor with panoramic bay views and unmatched tranquility. Proudly built and owned by one family, this legacy estate offers over an acre and 6,000+ sq ft of living space. A nostalgic Cape with a grand wraparound porch, open floor plan, sunroom, and chef’s kitchen with dual stoves, sinks, refrigerators, and walk-in pantry. The main level includes a spacious primary ensuite, while upstairs offers three bedrooms, guest bath, laundry, office, and a second primary suite with private deck and cedar-lined walk-ins. All bedrooms feature water views. The third-floor flex space is ideal for a studio, gym, or lounge. A 3,000 sq ft garage below provides soaring ceilings for boats, cars, or workshop. Fenced yard, detached two-car garage, and just steps to private beach, Onset Village, and full-service marina—this is a rare coastal retreat.
