I could easily spend more on the professional. Besides, how could he analyze such variable materials? A rubble stacked foundation of broken concrete and salvaged brick, earth walls with a mix of earth, sand and straw that varies slightly from batch to batch, a roof and walls of salvaged lumber, and a glazing of salvaged glass of unknown quality.
I guess I should amend my question; is there a precedent for a cob structure with 18 inch load bearing walls? I am not in a seismic zone.

Thanks for the detailed answer. I will go through it more thoroughly when I have time.
Just a quick clarification; so you are saying that I have exceeded the bearing limit for the underlying clay soil?
