Welcome to Granite Point—an exceptionally well-built, year-round estate on sought-after Grindstone Island. Constructed in 2022 with an uncompromising focus on quality, durability, and long-term performance, this property offers a rare opportunity to own a nearly new, expertly crafted waterfront home at an incredible value in the Thousand Islands. Set on 8.2 private wooded acres with access to the island road network, the offering includes a 4,235 SF main residence, two barns, and 520 feet of prime waterfront with sweeping views of Canadian provincial park islands and award-winning sunsets—just moments from Canoe Point State Park and Grindstone Winery. Built to last in a river environment, the home features HardiePlank siding, metal/asphalt roofing, energy-efficient windows, and high-performance systems designed for year-round comfort and low maintenance. With 10’ ceilings throughout and exceptional attention to detail, the residence offers both scale and craftsmanship rarely found at this price point. Inside, the home offers 5 bedrooms (3 ensuite, including a first-floor suite) and 5.5 baths with custom cabinetry and tilework. The kitchen is designed for entertaining, featuring dual SubZero refrigerator/freezers, two dishwashers, dual sinks, soapstone counters, inset cabinetry, a walk-in pantry, and premium appliances including a Viking propane range, electric wall oven, Miele speed oven, warming drawer, and built-in ice maker. Living spaces include a great room, formal dining room, and den with gas fireplace, along with a dual wood/gas fireplace. Systems include two high-efficiency heat pumps, central air, circulating hot water, whole-house stereo, motorized shades, Starlink internet, and exterior security. The Red Barn (28x60) includes a guest apartment, while the Gray Barn (26x36) offers storage, workshop space, and loft. Outdoor living features an ipe deck, covered porches, and dockage for four boats—perfect for enjoying the award-winning sunsets. Supported by well, septic, and a buried propane tank. A rare blend of new construction, superior build quality, and prime Grindstone Island location—Granite Point is a true legacy property
