I am currently building a 1000 sf Cob Barndominium, which is the only Barndominium I know of to use cob. Just seach Cob Barndominium in Youtube and you'll probably find it; channel name is John White.

I am a bee keeper, a wine maker on hiatus, father, husband, and a Navy veteran. I hope to learn and and teach while here.
