Below are some renders of an unfinished structure I've made to protect a stack of wood next to an existing shed.
It's made of a very simple frame with a pin-and-hole fastening setup at the ends that attaches to the existing shed's support structure. The cube is just a representation of the shed, but the two dangling pieces (just touching the shed) are actual cutaways of the support structure of the shed that the frame is being fastened to.
I intend on covering the frame in sail fabric, but then I'm not sure how to transition the asphalt roof of the shed to sail fabric so that the rain going down the slope of the shed's roof doesn't fall off before it gets to the canvas roof. Looking for ideas.
