Exceptional bunker house -- Perched on the side of a cliff, literally above the St. Lawrence River Imagine a residence that defies time and prying eyes... Hidden on the side of a steep cliff, invisible from the street, this unique property offers complete privacy: no neighbors, no direct views, just you and the immensity of the landscape. Built like a true modern bunker of ultra-sturdy reinforced concrete (1½-inch diameter steel rods, massive steel beams), it combines rock-solid strength with bold architecture that seems to float above the water. This house is not just a residence: it is a private fortress, an extraordinary refuge.
