The heart of the home is a light-filled open-concept living space designed for gathering and entertaining. Walls of windows frame captivating water views, while the expansive waterside deck provides the perfect backdrop for sunset dinners, summer celebrations, and evenings overlooking the harbor. Launch a paddleboard or kayak from your private dock, take a swim, or spend the day exploring the waterways that make this location so special.
