This cave, known as Caveland, carved into the Missouri limestone, was bought and renovated by Curt and Deborah Sleeper in 2003. The family spent four years renovating the cave to create a home and office space, all the while living in a giant dehumidified tent.

On their website, the couple have documented the hard work, creative thinking and roadblocks that went into making their cave home a reality. Initially, they planned to “build a geodesic dome in front of the cave, treating the cave as a sheltered backyard, or a giant basement”, just as this couple did when they built their home within a dome.

After some back and forth with the city authorities, the pair hit on the idea of building in the front of the existing wall, to open up the space while meeting the city’s approval.
