Looking for cob development in Washington State

I live in the Seattle area, and was looking for some current constructions of cob buildings or ovens that I could either volunteer some time working on, or at least visit and discuss methods used. I am a student at the University of Washington, and am doing my final work on the construction of cob housing. Since I am graduating in June, I need to find a place sooner than later.

So, if anyone in Washington needs a volunteer, or lives in a cob house and would like to share their process, please let me know!
