Great job, Hive account@indigoocean. For a rough sketch it looks pretty good. It looks like my typical rough sketch. You probably already plan to, but I might suggest solar panels and maybe a wind turbine, if there is enough breeze, for electricity.

I couldn't quite make out the kiva, though. Wikipedia says they are square-walled, underground and used for spiritual ceremonies by the Hopi and Pueblo people. Not knowing much better, at first I thought it to be a couch in your sketch, as I used to have as couch in that shape ... :) If I'm reading it right, I would think being rounded like your sketch appears to make it would be better for spiritual/energetic reasons. Watch it be a fireplace or something... LOL

Just brainstorming a little, I did want to ask if they use basements in that area. Maybe that's one use of the kiva too. I think I recall your mentioning plans to build more than one cottage. I would at least consider adding a full (or semi) underground basement floor or at least a smaller wine/food storage cellar on the one you would use. Maybe a kiva (or portion of a kiva) could be used. I say this because basements are good isolation/protection from the elements.
