Cob: large openings in walls, cob included

[Amanda Peck]

Darel reminded us of these guys.  Thank you.

Jill is contemplating a large opening to turn her kitchen from cozy in the 
winter to expansive in the summer.

This option does require a (ferrocement?) dome both for strength and 
clearance on the upper reaches.  And something on the order of an awning or 
porch roof so that rain cannot fall straight down and into the kitchen. I 
for one would want it screened.  AND sealing on the bottom (sides?) may not 
be up to household standards. Oh, yes, AND it might be difficult to put 
glazing in this.  And a few other things.

All of which doesn't mean it's not a lovely efficient idea that I'm thinking 
about myself.  I do tend to see--look for--problems.
