Hello dear @mountainjewel.
This design is shurely more like a portfolio showreel of what I learned in the 7 month course and absolutely everything applied that was possible and made sense.. For the work of the real piece of land It will shurely be a guidance (as you might have seen, the stoe retaining wall and terrace plus micro pocket pond became reality already), but many things will change on the way..
Just like the Permaculture Priciples 4 and 12 are saying: Apply self-regulation & accept feedback // Creatively use and respond to change.
But one thing is shure. The travel with this land will be long, slow and intense.
