I also would be happy, it the developers would put in additional (small) footprints for such items.
I mean, come on, a vet holding some grandfathered smaller houses, may not even have the room, to place that thing into a small tower or where ever this may be mostly needed for storage.
If an additional footprint would be added (selectable like the versions for holiday trees) in mini house size, that would be a welcome addition.
Also wonder what would happen with its content in case of the house falling as IDOC. (The same question for mannequins and their equipment.) Will these vanish or still remain lootable?
