Have a small house that we're thinking of adding on to. Have talked to the city about what I can do on my lot as our situation is a bit unique.
City tells me where I can build, but notes that I'll need a frost-depth foundation.
Pic below gives an idea of what I want to do.
So, my question is this: How do I install a foundation like that if it's as deep or deeper than the current foundation without disturbing the existing footings? Do I only put a foundation on 3 sides of the addition and tie in one side to the house framing? If so, I still have 2 ends that would butt up against the existing perimeter foundation to worry about.
Just wondering out something like this is normally done.
