[Cob] cob--house plans

[Amanda Peck]

Here's a handful for straw bale.

Both have THICK THICK walls.

It may be easier to get strength in a cob wall with curving walls, 
buttresses and the like, although some of the early English ones may have 
been done with some sort of slipform form.

I do like that drawing of the three-story dome.  (Not sure I'd care to LIVE 
there, but....)
