I am no construction guru, that is for sure. I was simply going to just do a roof with pressure treated four by fours in the ground on piers. The shear needed to be addressed, hence the large joists on the back and corners. Solid as a rock now. For the roof I just went to the local hardware store that has a lumber yard and bought brown corrugated steel roofing to lay over the fiber board on the top. It worked out great, total cost was around $300 to build it.
