In other words, going down below ground rather than up above ground. I am not asking about oil wells, mines, or boreholes -- I'm asking about inhabited/in use structures. In addition, I think I'm more asking about number of floors rather than vertical depth.
So a way to rephrase the question might be --
What building on Earth has the highest number of accessible sub-surface levels?
