[Cob] cobbing in Czech Republic?

[talismama]

I noted someone on here a few months ago writing that he wanted to  
possibly build a cob house in the Czech Republic.  I tried to write  
to his email address but it was sent back to me. Any information on  
this (or maybe Slovakia, Poland, Austria)? I am in the Czech Republic  
and looking for opportunities to help build.
Thanks!!!
