Building with cob -- what should I include in a presentation about it?

I have a presentation to do on building with cob. What are some important points I should bring up?

What type of group are you presenting to?

That has a lot of bearing on what to cover and how to cover the subjects involved in cob building.

people that have never heard of cob are going to need a lot more basic information than those who are even a little familiar with this type of building.

Another thing to consider is how familiar you are with the subject of building with cob.

Its to my materials construction class. I don't think any of them have heard of it because they are more main stream guys. Basically I need to use terminology I've learned in the class while describing cob, and is characteristics. Thank you for any help you can offer.

I would go over the following, to past code and to explain to classmates:
1) Foundation+Stem Wall+Floor - Concrete/Rubble Trench + Water Drainage, 6-mil poly, gravel (4inch+)
2) Insulation - Roof + Outside Stem Wall + Window
3) Bond Beam - Extra Strength + regular roof
4) Overhang (rain+cob wall) -
5) Present a super simple boxy/regular floor plan nothing circular/underground/etc
6) Don't mention humanure/greywater systems, one new thing at a time

Post and beam construction with non-structural strawbale stacked insulation with a cob "plaster"
Post and beam construction with non-structural mush of "clay and sand" or "organic" aggregate
"Unburned clay masonry" when used in a structural context, unfired bricks or natural masonry.  

Cob Wall are usually 24 inches (61 cm) thick. So the size makes them strong collectively even if "weak" singularly.
