What's special

Three car garageTrue walkout guest suiteExtensive stone patiosExpansive sight linesCircular drivewayGenerous storagePrivate beach access

Exceptionally located less than a tenth of a mile from both the town green and beaches - with your own private beach access - this stunning residence sits on 1.57 secluded acres and has been completely re-imagined with uncompromising attention to detail and the finest materials. The home offers 16 thoughtfully designed rooms. Sun filled interiors feature over sized windows and expansive sight lines, anchored by a massive family room and a top of the line chef's kitchen. The lower level is a true walkout guest suite with additional living space plus a separate garage apartment for overnight guests. Outside amenities evoke a private resort: a gunite pool, extensive stone patios, two fully equipped outdoor kitchens, and a charming grassy area framed by mature landscaping for complete privacy. This is a rare coastal estate that blends modern, high end finishes with relaxed, year round seaside living. Practical luxury continues with a three car garage, circular driveway, and generous storage. This is truly a must see, and all reasonable offers will be entertained.
