I'm gonna build one in the Spring so the grandkids can hunt my plot. It'll be 4x8 outside dimensions so I don't have to rip more OSB than necessary. One side will be 8' tall and the other 7' so we'll have headroom and good roof pitch and only lose 1' of OSB across the back. My biggest obstacle will be getting posts in the ground. It's not very far down to rock.
