question about building a shed
I'm about to start my first fairly major construction project. I'll be building a 12' x 20' shed with a standard gable roof. There's potential in a couple years that I might need to move the shed to another area of my property, so I don't want to have too permanent of a foundation for that to be possible.
I'm planning on using solid concrete blocks for the corners and then having them every 5' running along the 20' length and every 6' running along the 12' width (i.e., three rows of 5 stacks of block). I was planning on using PT 2" x 8" for the floor joists with a mud sill plate on the 20' length of each side.
Would it be better to build four 6' x 10' sections of floor and join them together with the joined together sections all supported by block, or just build one large floor with a 12' span of joists?
Thanks for any help or suggestions you can provide!
