The custom cook's kitchen with handcrafted cabinetry opens to an inviting living area where a wall of glass frames the ever-changing waterfront landscape. Gentle ocean breezes and abundant natural light create a comfortable atmosphere throughout the seasons.Outside, a climbing hydrangea arbor welcomes you to a private brick patio and beautifully established gardens overlooking the water. It's an ideal setting for morning coffee, afternoon gatherings, or simply enjoying the peaceful shoreline.
