Background, long story short: I have an old shed that is basically barn construction. It's about 12' x 16'. The thing used to sit on concrete walls and those walls deteriorated. So I jacked it up, and put it on 6" posts, with deep concrete footings (~42"...it's Ohio).
Now that the building is once again solid, I need to finish the ground around it.
The building is built into a slope, where its front and one side are level with the yard. So the slope runs diagonally across the building, front to back. The front sits on an existing (and massive) concrete footer in the ground. The side into the yard is my concern right now.
What I want to do is simultaneously contain the slope and provide enough of a finish to make the space under the building into useful storage. The old concrete walls used to provide this, but now it's sitting on posts, so there is a lot of open space around it that I need to fill. The side in question has two posts, at the halfway point and on the back corner.
Is there a way to build something between these posts that would serve as a retaining wall, while not interfering with the posts? I'm open to ideas.
BTW...I'm not sure what tags are appropriate for this problem.
