Storing wood outside is not ideal as anyone with experience with a wood stove will tell you. It never really dries properly unless you cover it or store it out of the elements.
I decided to go real simple and functional. I wanted a woodshed but I also wanted a place to store a ladder, yard tools and our portable generator.
I decided that patio blocks were sufficient and I build a box frame out of 2 X 8's over the blocks. In retrospect I could have screwed the boards down instead of nailing them but it is strong enough and should last a long time. I bolted (using lag bolts) pressure treated 4 X 4 posts to the box frame which slip into the patio blocks.
On a final note. There happened to be three small pines in front of the woodshed that I decided to leave there. They add an interesting element to the structure.
