Burnside House, one of the region's most storied stone residences, stands proudly along the St. Lawrence River-just 5 minutes from Brockville's downtown. Built in 1829, with portions believed to predate into the 1700s, this landmark estate offers over 5,600 sq. ft. of living space, 6 bedrooms, 6 baths, and a rare blend of historic craftsmanship and modern comfort. Thick stone walls, original architectural details, and expansive principal rooms define the home's character. The main level features a parlor, a bright sitting area with a fireplace, and a quartz finished kitchen with generous counter space. The great room anchors the central living space, and just off it sits a private office with a separate entrance, supported by a highway commercial designation that adds future versatility. The upper level includes a 2 bedroom loft, complete with its own bathroom and sitting area-an ideal retreat for guests or extended family. The lower level showcases beautifully exposed stone, abundant storage, and a secure safe room, offering a striking reminder of the home's long history. Outside, the grounds are meticulously landscaped across nearly 5 acres, flowing naturally toward the river and creating a picturesque setting for relaxation and outdoor enjoyment. Along the waterfront, the property features over 200 feet of shoreline, a 50' x 70' concrete Kehoe dock with two boat lifts, and a waters edge outbuilding complete with a covered patio above-perfect for entertaining right at the river's edge. Whether boating, gathering with friends, or simply taking in the sweeping views, the waterfront is a defining element of this estate. Burnside House is a rare opportunity to own a historic stone residence with remarkable scale, architectural significance, commercial potential, and true St. Lawrence River living-an iconic property along County Road 2.
