Another one of those quirky little English language anomalies.
Now, as to substance; Do you really want to force the builders of these cracker box homes to make them substantial? That costs money. Now, it makes more sense to have the cheapo houses built on a slab…no basement at all. I owned a house like that in Oklahoma…there they refer to them as “Indian Housing”. Luckily for me, it did burn and I replaced it with a house of my own design…still, I stayed with the slab. In my mind, a basement is for growing mold and holding excess water…useless.
I have a “basement”...cellar? under my current house which is 130 years old. I last went down there about five years ago. It looks something like an Edgar Allan Poe novel.
