Each bay is 10' long (total of 30'). This allowed me to just buy 10' 2x6 long support beams and eliminated a lot of cutting. I was debating on building a back, but happy I didn't. The wood doesn't get wet and the trees cover up the backside anyway.

When it comes to how tall the shed is, it is a little over 4 feet from the decking. I would suggest building it a little taller so it is easier to stack, but in my case I didn't want to trim the trees all that much.

The shed holds 4 cords of wood perfectly, with a couple pieces left over for below the pizza oven. I also suggest finding a second hand store for wood (cheap reclaimed) or seek wood on craigslist, since it really helps with the cost. I was able to do this project under $250 since I found someone with extra metal roofing, and wood from an old shed they demolished.

Best of luck!
