This quirky home in Bisbee, Arizona, offers a real upstairs/downstairs vibe. Built in the 1980s, the previous homeowners employed a Swedish mining technique to create the walls and ceilings, resulting in a stone home nestled into a cave. But if you’re craving a bit of sun, take the spiral staircase to the airy loft, which offers plenty of natural light, access to the in-ground pool and views of the surrounding Mule Mountains. The 3-bedroom, 4-bathroom home is on the market for nearly $1 million.
