Escape the ordinary to your sanctuary on Stone Road. Located at the end of Stone Road with views of Superior and the Duluth skyline is a custom stone triplex on 80 acres that offers so much and has so many potential uses. This amazing hand-crafted home was built by 3 family members as a safe place to get away from it all. This truly unique underground home is built to stand the test of time with a stone and mortar exterior, a living roof on top of a newer rubber roof laid over Spancrete, prestressed hollow core ceiling slabs for the ultimate in strength and durability. The walls and interior structure are a mixture of poured concrete in high-load areas and concrete block in other areas to create storage rooms and interior walls. Each unit is unique in the layout and configuration, but they all have 3 bedrooms, 1 full bathroom, and a well-appointed kitchen with pantries and storage spaces. One thing that sets this tri-plex apart is the fact that it features large common spaces. The upper level has a large lobby with access to the upper 2 units and the stairs to the lower level. It also provides access to the back stone-walled courtyard and stairs to the living roof. The lower level offers approximately 2520 sq ft of common space. This common space has a large rec room, a 3/4 bathroom with cedar lined sauna, a shop/storage room, office space, wood storage room, utility room, a canning kitchen, shared laundry with 2 washing machines and 2 dryers, and access to the attached 8 car garage. Heat is provided by combination propane/wood boilers. For the ultimate in preparation, there are 2 wells on the property providing plenty of fresh water for the residents. Built by preppers for preppers, there are back-up valves, meters, and many other features "just in case. " Use it as a corporate retreat, short or long-term rental, a custom escape compound, a large multi-family or group retreat, or a great place to live off-grid and off the land. There is a large generator house that is now empty and a large tower for the old wind generator. The 8o private acres of land is amazing with apple trees, frontage on the Little Amnicon River, the original quarry from which the stone was sourced a 25-300 yard shooting range, and 5+ acres of cleared land that would be perfect for gardening or enjoying the vistas. There's no other property like this in existence, and if you had to build it today it would cost you millions.
