An ultra-rare chance to secure Dorval's largest waterfront lot and build a landmark estate within the exclusive Royal Quai enclave. Set on 38,330 sq. ft. along Lac St-Louis, 1 Kathleen-Laing delivers sweeping east, south, and west exposures--sunrise to sunset over the water. Commanding views, unmatched scale, and total privacy just 20 minutes from downtown Montreal and 10 minutes from the airport. This is more than land. It's a legacy opportunity to create one of the most prestigious residences.
