Could you design a trailer park? Like, maybe four micro homes on one lot, with an outdoor common area? I know it wouldn't function as a micro home "technically" with the tile counter, but it would just be for the aesthetic, and allow for several sims on the lot.
Such a cute little micro home! As for the builds working for you when you play-test vs when people can't make it work, I'm almost positive it's due to people not enabling moveobjects cheat before placing lots. That messes with a lot of small builds like this where you have to maneuver things in specific ways.
