OK. I'm going to bring this thread back up to the top because it was the closest to what I was searching for.
We are starting the digging for a basement which will be under a cabin when we finish. This is all brand new stuff, no existing structure or basement already.
We have never done this kind of thing before. We have researched it, talked to people who have done it & adjusted plans so it will be suited for a fallout shelter.
Has anyone here done this type of thing before? How did it go? Do you have any advice or information for those of us doing it?
I feel like this should have been done this summer but... it wasn't.
Chime in if you have something constructive to tell me. TIA
