sims 3 has basements, so i call dibs on the dank subterranean bunker.

Someone once raised the idea of having a sealed basement with one hideous introverted artist in it, without the knowledge of the people living in the house. The artist makes art and sells it all day to generate money for the family, which lives in comfort, oblivious to the existence of an enslaved art goblin in their basement.

I'll confess I've never actually played a Sims game so I don't know exactly how the mechanics would work, or if it even could in this version, but the story was funny.
