I am building a small shed. I was planning on using concrete blocks in the corners as footers, but neighbor has put out some PT 4x6s and I am thinking they would be better.
I know they will rot out eventually, but 20 years is certainly long enough for this project.
Does it make sense to put the shed on a little box made of 4x6s? The ground is a thin layer of dirt over solid shale, so it should be pretty stable.
