My concern would also be that the straw clay would only be able to dry from one side and that the cob would add to the moisture content for a long time...too long to dry the wall out safely.<div>Building the straw clay wall first and then adding something like adobe to the interior could work.</div>

My concern would be drying for the straw/clay. We have a hard time
getting straw/clay to dry in our warm but humid summer. We count on
a week per inch of wall thickness, and that's with both sides of the
wall exposed. Sometimes we have to help things along with a fan on
the interior because the drying is slower in the still air. With one
side of the straw/clay up against cob (which may still be drying
itself?) I would worry about the straw/clay not drying out at all
before it starts to get mushy in there.<br>
<br>
What about double wythe cob with a dry insulation in between? <br>

So our idea was to build a wall that would look like this, from
inside to out:
<div><br>
</div>
<div>14" -- 18" of load-bearing cob</div>
<div>8" -- 12" of light straw-clay</div>
<div>lime plaster</div>

</div>
<div>Has anyone already done this, or heard of it? Any reports of
