Too cute for words
Rammed Earth houses are all the rage in the southwest right now. I don't know much about that. Watched a show a while back on straw houses (little pig, little pig) and they actually seem fairly secure. You build them out of two layers of straw bales, reinforced with rebar, and stucco the outside. I don't remeber the R-value, but it was high. Fairly well windproof as well. I think if I were building a new house, I would seriously consider concrete myself.
