hi Dillon Nichols, thank you for your answer.
I'm living in this old house, Brazil, in a place called chapada diamantina.
I has raining season every year, nights are cool, days are hot, in most of the time, it's windy.
I'm very new to this, and I didn't formulated well enough my question, because there are many and I'm very insecure to the subject.
I would like being refreshed with some ideas on what can I do solely with cob, is it possible to improve structure, can I use cob in some manner so I can reinforce the existing walls? I was thinking an upper floor, at least over one room of the house. I'm open to any crazy ideas to make it work.
