I'm just watching Dirty Jobs, and they went to retrieve a skunk from underneath a house. There's some shaft on the bottom of the house, and they went in, so they were underneath the actual house. I've seen it many a time in American movies, but have never gotten it. Why are houses built with the little bit of space off the ground? You can't tell from the outside that there's any space. I'm sorry if It's a stupid question, but all houses here are built with brick and cement and stuff, and even when the house is raised a bit from the ground (there are steps to enter it), the foundation is completely solid.
