Cob: cob domes

[Darel Henman]

Ben,
   here is a Japanese page that has pictures of the construction of a
daub (cob) dome-like building.  The Japanese letters wont come out on
your computer moniter right, but the pictures tell a lot. 

In this structure, I assume it is a test structure of some sort, they
have constructed a building umbrella from woven bamboo material and
oiled paper.

I don't understand why its open, or appears so in the middle, unless its
for smoke to get out????
