Why would I want to live in a cave, or even a cave-house?”
Well people have not only been utilising natural cave formations to live in for thousands of years, but actively hollowing them out of cliff faces. In certain areas of the world where soft sandstone cliffs are common, it was actually easier for our prehistoric ancestors to carve out a warm, dry cave-house than to build a standalone structure.
Today Spain still has thousands of modern day cave dwellers and many regions have villages which consist entirely of cave-houses. Some of these regions can trace the history of the traditional cave-house back to Arabic Spain over 500 years ago.
