I'm so building some kind of earthen circular home someday. If you've never been in one and come across one, go inside it if you can. It feels completely different than a wood frame and insulation house. Being surrounded by earth is literally grounding and calming.
I fantasize about making a circular bed that you have to kind of crawl down into, that's all super fluffy inside like a nest, and hanging some kind of changing color rainbow light sculpture on top of it. A friend pointed out to me that that sounds like a tripper crib. Giggle.
At some point I'd like to travel around helping make sacred spaces for people, with earthen architecture and arts. My friend James Gyre at Naked Geometry makes incredible laser cut wooden panels. One way to get natural air conditioning is to put a grid like that at the bottom of a fire flue and wet it - some of the geometries you see in middle eastern architecture are functional!
