So my house is approximately 10 years old in Portland, OR. Our "basement" is currently a crawl space (actually, it's more of a stoop and walk space, it's about 5' from floor to ceiling). My question is, would it be feasible for me to dig down another, say, 3-4 feet, so i had a full basement that i could finish? Or, would it make my house collapse?
I'm guessing that i'll have to get a pro in to do at least some survey work and get permits and stuff before i even buy a shovel, but i figured i'd ask here first as it may well be univerally known that this is impossible, and i'm just having foolish pipe dreams!!
