Thanks for sharing, looks like you have put a tremendous amount of thought into what you want to accomplish. I have a couple observations. It is hard to fully see what you are trying to do from the drawing. Make sure you allow for expansion, hay & grain storage, you can never have enough. You probably have already done this but study up on permiculture, there is a lot of insight in its teachings especially getting your land set up properly. Good luck! it looks like you have a lot of work ahead of you, keep us posted on your progress.....
