About this home

Welcome to Granite Point, an exceptional year-round estate on Grindstone Island. Built in 2022 with no detail spared, this thoughtfully designed property blends timeless craftsmanship with modern efficiency for an extraordinary Thousand Islands lifestyle. Set on 8.2 wooded acres with access to the island road network, it features a 4, 235 SF main residence, two barns, and 520' of waterfront with sweeping views of Canadian provincial park islands and spectacular sunsets—just around the corner from Canoe Point State Park. The main house offers 5 spacious bedrooms (3 ensuite, including one on the first floor), 5.5 bathrooms with custom cabinetry, tiled floors, and designer wallpaper, and 10’ ceilings throughout. The kitchen is ideal for large family living and entertaining, with two dishwashers, two SubZero fridge/freezers, dual sinks, soapstone counters, inset cabinetry, and a walk-in pantry. Cooking is a breeze with a Viking propane range, electric wall oven, Miele speed oven, warming drawer, and built-in ice maker—a welcome feature for island living. Enjoy entertaining in the great room, formal dining room, and den with gas fireplace, or relax by the dual wood/gas fireplace. Systems include two high-efficiency heat pumps, circulating hot water, central air, whole-house stereo, motorized shades, energy-efficient windows, Starlink internet, and an exterior security camera system. The Red Barn (28x60) includes a guest apartment with kitchen, living area, full and half baths, and attic storage. The Gray Barn (26x36) offers vehicle storage, workshop space, and an overhead loft for kayaks. Outside, enjoy the ipe deck, covered porches, and dockage for four boats. With Hardiplank siding, metal/asphalt roofing, well, septic, and a 1, 000-gallon buried propane tank, this is a rare opportunity to own a beautifully built, low-maintenance riverfront retreat.
