Well, I actually have a few: Sewers, which you can enter from manholes, grates, etc. I think this would make a nice roleplaying addition. Maybe even a sewer hideout? Enterable windows; I actually thought this one out, you can remove the windows from the house meshes and make them into 'doors' which would even display that opening animation. See-through windows; you could add a lower detail version of the city outside of the interiors and add transparency to the windows. Some ways for thieves/assassins to get around un-noticed ( sort of like shenks's thievery overhaul) clicky Thank you for making this mod.
