Interesting post. I've been going with the ideas I've seen around
here. Basically portable sheds, albeit at 8x12 or 10x16, "portable"
becomes an interesting feat.
This "shed" however is likely to need to be moved in the future. I
will lift the skids off the ground by 3" to 9" on concrete blocks, etc
to get even the PT 4x4s a bit more "room". My joists are PT as well.
Planning to use 4 skids along the 12' (long) side. So 1' in, skid,
3', skid, 3', skid, 3' skid, remaining 1'. Atop those, and
perpendicular, 7 12' joists capped on the ends with an 8' 2x4. 3/4" t/
g osb-ish flooring (primed and painted on the top side (maybe bottom
and edges as well), then the load bearing wall --- the 12' long one --
will sit atop the 12' outside joists. I'll frame up about a 6' high
wall and then a gambrel roof atop those -- again with the load bearing
side being the 12' long wall.
