Malcolm,
	"could the buttresses be straw bale walls?"
	No. Being that the purpose of a buttress is to support a wall from shear forces. How is a straw bale wall going to support a cob wall when the cob weighs probably a hundred times more than straw bale? It's not going to amount to much resistance should that cob wall come crashing down.
