Basements are most common in cold weather areas where the foundations must be sunk four feet or more below the surface in order to prevent frost heaves. Once you’ve sunk your foundations that deep, digging a few feet more to make it a basement is pretty much a no-brainer. I’ve never lived in a house with a basement myself, but that’s because I refuse to live anywhere that has below-0F winter temperatures or a frost line that goes more than six inches deep in winter.
