Presenting an unparalleled opportunity, this expansive 28.63-acre Lake Ontario waterfront property boasts approximately 1,400 feet of direct shoreline and an existing estate residence. The home offers a beautifully maintained home that can be incorporated into a proposed development, severed from the additional land and kept separately, or immediately moved into for exceptional, private, waterfront living. Strategically located within the Lakeport Settlement Area, the site offers significant potential for a visionary residential subdivision. Alternatively, its vast acreage and stunning natural features create an idyllic canvas for a luxurious private estate or a premier recreational haven, appealing to those seeking exclusive privacy, strategic investment, or diverse outdoor pursuits directly on the waterfront.
