Important - "Structural Solutions" mod required! I wanted it to be clean and white (i.e not ficsit walls). Since the default concrete does not allow for +5 contrast for perfect white, I used this mod as the concrete walls can be white.

503m(ish) tall, Sci-fi themed skyscraper ready for your next factory! Almost completely empty inside.

There are 2 4-car train stations in the base (one in each direction), and 2 drone ports at the top (with power connected, and batteries stocked).

I used the default concrete pallet with the white at +5 contrast, and swatch 4 with dark grey primary.
