You'd need dynamite to build them there because the bedrock is almost at the surface. Few people there even have basements due to that.
Thats completely untrue.
Most homes here don't have basements because:
1) we don't have a deep frostline, so there is little reason to dig the foundations that deep.
2) We have heavy clay soil which heaves when saturated with moisture which causes basement walls to crack and leak.
3) Since we don't "have" to dig deep for foundations, it is less expensive to build up instead of build down.
