Yes, there are people who've made cob houses with no straight interior walls, but a good many plans use either cob or stud walls in areas to create noise blocks or privacy, and these can form "straight" locations for standard cupboards/fridges to be located against.
spend a few hundred dollars and a few days to make internal stud walls with sheetrock if straight walls are important.
As they say in the Real Estate business, "Location, location, location." In the winter our lower field turns into a pond if we have a big rain, but I *still* have trouble getting it to soak in deeply due to the rock and clay content, although it's way better than when we moved in. I don't know what management practice (maybe beavers?) would help in your eco-system, but there's lots of "dry-land" permaculture happening world wide with great results, so try not to loose faith!

I don't get it. A whale wearing overalls? How does that even work? It's like a tiny ad wearing overalls.
