Villains Building design and renders

Design for unnamed villain's building. Inspiration for helipad is that building from Dubai. There is a very very basic interior for the "lobby" area, with 6 lifts (well, recessed walls that will be textured as lift doors).

OK a little extra detail, as seen in the design image:
There is an antenna on the roof, which could double as a LAZOR!?! Or... Just an antenna. You decide!

There is a little door on the front of it, below the helipad, these would open up to allow fast deployment of aerial drones or getaway vehicles.

There's a big TV screen on the front so that the villain can be one of those over the top kinds who threatens you over the giant screen... Or not.

The lower floor, to me, feels a little too empty structure wise. In other words, I had a look at the loddy and thought "how is the rest of the building being supported?" This can be discussed in class.
