[Cob] building

[Jill Hogan]

Hi Damon the problem with that we have found is that the post expand and 
contract in the wall and crack the cob/plaster over the posts. I prefer 
to educated the building inspectors to the hundred of years old houses, 
in say Devon and Cornwall in England, with no posts in their walls and 
if that is not an example of duribility heaven alone knows what is. The 
thick walls might not let the sun heat in but they certainly hold the 
heat generated from my fireplace and my wood burning stove, keeping the 
house warmer through winter, with out the use of electricity, than any 
other house I know
