When an interior world is requested then all the buildings that are assigned to that world are loaded. Meaning if you request interior 15 then the Jefferson motel, the bloodbowl stadium and the binco will all get loaded and it is actually possible to fly between them through the void if you can clip through a wall somewhere with a jetpack (or using airbreak). This is particularly true for the "World of Coq" interior in world 1. You will be able to actually see the Transfender interior floating in the void a few meters away.
