Tucked into the forest canopy of Grindstone Island, Stones Throw is a rare glass-walled post-and-beam home offering complete privacy, energy efficiency, and a front-row seat to the beauty of the St. Lawrence River. Set on the Northside of Grindstone Island. The main house features a first-floor bedroom with full bathroom and two additional bedrooms upstairs with a second full bath. Soaring beams, floor-to-ceiling windows, a cozy wood stove, and a fully stocked kitchen create a warm and welcoming living space. Morning light filters gently through the trees, casting a soft, natural glow indoors. Equipped with six rooftop solar panels, making it both environmentally conscious and cost-efficient. Step outside to the front deck overlooking the river—an ideal space for outdoor dining, sunset cocktails, and soaking in panoramic Canadian Provincial Island views. A post-and-beam guest cottage includes 1 bedroom, a full bath, and a loft—perfect for guests or a creative retreat. The square footage 1540 includes the guest house. A large Country Carpenters post-and-beam barn with electricity offers flexible space for storage, workshops, and more. A short walk to the shoreline with floating boat port with generous dockage, perfect for larger boats or multiple watercraft. The river channel is quiet and serene, offering ideal conditions for swimming, kayaking, and wildlife watching. To make riverside living even more convenient, the property features a private funicular, a motorized rail lift that easily transports gear, groceries, or luggage from the dock up to the house. With direct access to Grindstone’s trail network, you’re steps away from hiking, biking, and exploring the island’s natural beauty—including the nearby Thousand Islands Winery, a favorite local destination. Stones Throw is more than a home—it’s a sanctuary. Surrounded by nature, a rare and remarkable lifestyle in the heart of the Thousand Islands. The property is being offered completely furnished, ready for the next owner’s enjoyment and comfort. With architectural beauty, modern efficiency, and seasonal appeal, this is the perfect private escape. Schedule your private showing today.
