Hey all. I'm in the process of tearing down part of my building that was not on a slab, I'm not looking to spend a fortune to pour a new slab so my plan is to just pour footings and put a floor on them. My question is how many footings will I need under the floor? About all I definitely know is I need footings around the diameter of the new addition which is ruffly 8×14. Should I have footings every 24 inches, 12 inches, or just pour a footing down the middle? Also another idea I thought... whould it be cheaper/ better to use pre fab concrete joist holder's under the floor vs footings? Thanks
