Permaculture doesn't mean one thing, it means working with your resources available on your land (as much as possible) and built for your climate.
That could be rammed earth, that could be stacked stone, that could be
cob, that could be
straw bale, that could be earthbag, that could be Wofati.....
You will notice all those methods have 18" thick walls (or so), so the same design will translate to any of the materials fairly easily.
I love rammed earth, as long as someone else is pounding it
But it doesn't like wet weather.
All but the strawbale are MASSIVE and need the foundation to deal with it. That can be REALLY expensive.
I would probably build a straw bale house next time, on a pier foundation. Three little pigs be darned--they had it all screwed up on the houses.
