I place the mini's inside sanctuary houses. The coots mini works well... sometimes have to rotate 90 degrees after building to allow straight access to the bed. I use the skinny interior plots as well, particularily to keep objects out of the walkways of the house... meaning some interior plots not mini or skinny, they will build objects that extend into other areas of house, blocking movement.
Example is the Red Yaoi Armor or the IKEA logistic station. I placed both of these in the living/dining room of the workbench house. The IKEA has a storage locker that will block the entry door and swapped, it will block the old kitchen access. The Red Yaoi has that monstrous mouse armor on a minuteman mannequin that blocks the old kitchen....
Yes, I know you can "move" these items, but just regenerates later on in original position. And this isn't to say bad plots, just not the right ones in the locations.
Takes some doing, but the houses can be used.
