Property Description

Set high above the shoreline with sweeping western views across Long Island Sound to the Connecticut coast, this exceptional East End estate offers rare privacy, scale, and direct beach access alongside Friar’s Head Golf Club. Designed to embrace its coastal setting, the five-bedroom, six-bath residence features light-filled interiors, grand living and dining spaces with a statement fireplace, and walls of glass opening to a wrap-around Ipe deck overlooking rolling dunes and manicured grounds. The professional-grade kitchen is built for entertaining, equipped with dual ovens, an eight-burner cooktop with pot filler, twin dishwashers, beverage center, and full-size and under-counter refrigeration. Resort-style amenities include an indoor pool with ozone/UV treatment, private steam room, elevator, and a state-of-the-art media room with integrated audio and short-throw projection. Guest suites provide privacy and comfort, while the walk-out lower level offers flexible space for recreation, fitness, or additional living. Recent upgrades enhance performance and peace of mind, including a new architectural roof, exterior repainting, solar panels, solar powered astronomy platform, high-efficiency generator, updated HVAC with Wi-Fi controls, and an on-demand hot water system. New sliding doors, retractable awnings, redesigned landscaping and driveway, gated entry, improved service access, and newly built stairs to the private beach complete the offering. Additional enhancements include a Tesla charging station, gig-speed connectivity, upgraded appliances, energy-efficient window tinting, and a custom astronomy platform above the shoreline. This is more than a home—it is a place where time slows, memories gather, and each sunset feels like a quiet reward. Meticulously maintained and thoughtfully enhanced, this coastal retreat offers a rare blend of modern performance, timeless setting, and enduring soul—ready to be enjoyed without compromise.
