I keep seeing the options out there as pad, crawl space, and basement. I live near a river, so maybe I'm wrong, but a basement seems like it's gonna be a constant worry, and my parents have expensive issues with needing repairs, since they're on a pad. My question is this, couldn't I ask for a concrete pad to be poured and then build a house on top of that with a crawl space underneath to get around the problem my parents have of needing to drill into it to do repairs? It also gets around the expense of having a full basement. Is thus a crrazy or crazy expensive idea?
