Nestled within the historic Malletts Bay Club, a private 12-home enclave established in 1915, this exceptional estate offers a rare opportunity to experience one of Vermont's most coveted waterfront lifestyles, with sweeping views across Lake Champlain to Mt. Mansfield. Residents enjoy over 1,700 feet of shared shoreline, deep-water docks and moorings, access to the privately conserved Birch Island, and 75 acres of club-owned land with tennis and pickleball courts plus hiking and cross-country ski trails. Completely reimagined and recently expanded, the home blends timeless design with modern luxury. The new first-floor primary suite is a private retreat featuring a gas stove, custom dressing room, and spa-inspired bath with heated marble floors and a Kohler rain shower. A signature feature is the indoor/outdoor spa, where a stainless jetted tub opens directly to the pool through folding glass doors for seamless year-round living. The chef's kitchen is outfitted with Sub-Zero and Wolf appliances, Bianco Mocaccino marble countertops, custom cabinetry, and a statement wood ceiling illuminated by Allied Maker lighting. The renovated family room includes custom built-ins with integrated LED lighting and a gas fireplace. All three bedrooms are ensuite, each upgraded with custom tile showers and heated floors.
