Hello,
You could us Roxul board over pressure treated studs (new pressure treated
yellow pine is no longer as toxic as the old copper arsenic treated stuff)
and then stucco with lime stucco ( sand and lime putty - bag lime and water
for a wall that will not absorb moisture, is insulated (Roxul board is an R
4.1 per inch) and be unfriendly to insects, fungus and rodents as well as
being nontoxic.  Fiberglass insulation will attract rodents and insect
infestation.
This is the Roxul site  www.roxul.com

could you build a cinder block wall for the other two walls and insulate
with a polyfoam (this is the only thing out there that I have found to
withstand the moisture) There are SIP, structural insulated panels that have
a cement outer core, different from the toxic OSB board that is more
popular. SIPs are big and may need to be special ordered - and it depends on
how close you leave to a manufacture.

treated wood on the floor (although bad) and untreated for the studs would
work if the blocks do not.

if you find a solution, let me know - this has been a design project on my
mind for a while now.
take care,
Julia
