[Cob] timberframe infill

	You definitely want to support cob with a stronger foundation than  
your timber frame. I would not build cob on concrete piers,  
especially spaced 10 feet apart, because it will crack the cob and  
possibly eventually collapse your building. If it was a continuous  
foundation it would be ok. You wouldn't need a barrier between the  
wood and cob. Seriously consider light straw clay instead of cob.  
It's specifically for your project because cob is too heavy.
