I stayed in a mongoloid home in Tunisia last year. It was lovely. It was a large, central, below-grade courtyard with dugout, underground rooms branching off it. The rooms were cool all day. By being below grade, the courtyard was in shade most of the day and didn't get too hot. Through clever tunneling, the rising heat generated a draft.

I also learned that mongoloid, at least in Tunisia, is not considered a derogatory term.
