I think optimising for resiliency, optionality & privacy will be my wider goal. Allowing people to largely do what they want on their peice of citadel will be fundamental.

Each of the private areas will be separated by pasture that's actively grazed rotationally.

I think the communal area will be where most of the fun happens. A clubhouse of sorts that can be accessed by outsiders without going deep into the private areas.

It may start as just an insulated steel shed with mezanine & plaster interior. A big wood fireplace. Bar & pool tables. Covered outdoor area for BBQing & socialising. 

Commercial kitchen & cool room for processing & aging meat will be nearby.

I think it will all evolve in time naturally but this is kind of where my head is at. I'd like to be a member of several citadels for increased geographical optionality.

I'm so glad others in my social circle are also considering this. Mistakes & strides will be made along the way but we can share the costs & lessons. Fundamentally this increased optionality will cost sats & I think everyone is keen to keep the optionality:cost ratio as high as possible.
