This former gold mine used until the 1960s is now a cliffside home on 33 acres in Big Sur, California. The 2,467-square-foot home listed at $2.2 million hangs over a cliff facing the Pacific Ocean with a separate guesthouse up the hill. The mine, which dates back to the 1880s, is still accessible by tunnel but no longer in use. The original cabin is now the kitchen of the three-bedroom, two-bathroom home. The home is made from redwood beams supplied and milled from the land, while utilities are sourced from a solar energy system and the property’s natural springs. Credit: Top Ten Real Estate Deals
