I have a very old home (circa 1840) and on the back of the home a wood shed was attached over the years on top of a stone foundation. The house is very solid all the way around and this 14 X 18 foot wood shed is my future kitchen.
The existing floor is too soft/spongy and will require a tear out with new joists and subfloor. The walls and ceilings have already been re-framed with 6 inch timber and new insulation added.
I have not opened the floor up yet and am only speculating on the job at hand. (I am not in NY where the house is) I am wondering if I could dig a "footer" in the crawl space around the inside of the existing foundation? What depth would it need to be dug to? If i can do this and lay a level layer of cement block it will give me a solid square and level platform to build on.
Thanks in advance.
