Random thoughts:

Another vote for compost toilets. Not having to locate/plan septic gives a lot of freedom. We've used only compost toilets for several years now and I wouldn't go back.

There's something particularly beautiful about houses clustered relatively close but then open land radiating out from that cluster. I think that there are probably a lot of examples of this throughout history. Makes social connections and defense easier.

Unless you have a culturally homogenous group, it can be very difficult to agree on aesthetics and building plans!

I would spend a lot of time looking at how human groups have created their spaces historically. A Pattern Language is a terrific book. Well worth a read as you continue your planning.

Love this energy 💕
