I just put mine going from the center of the front to the left. It is the only stairs going up. I have the little stairs going over each wall until I build higher. There is youtube video of one, just look up uo keep. There are at least two actually. The person did them on the right hand side and center and it looks pretty awesome. I hope to build similar or just outright steal the design!! (just being honest) She has amazing floors above as well. I didn't understand some of her(his?) design but overall, it looks grand.
