So I started this waaaay back, when i decided that the Tia' would be too small. As you can tell from the image, there is 20 floors. However, some systems and areas actually stretch across multiple decks- things like engineering and hydroponics (of which there are 3 separate zones for.) I don't have every deck fleshed out, mostly just the living quarters and the general exit for the hangers, but needless to say she is massive, and most all is to scale inside blender. It is massive.

I did draw some heavy inspiration from an old star trek ship that fit the design perfectly- the "Ts'usugi Super Capital". While the outside outline is similar, I intentionally left the main engine and nacelles as block shapes, to not have a 1:1 copy of the ship. That, and there is nothing on the internal layout for it. So creativity go wild!
