It is done!
Introducing the Supporting Cubix. Some parts of this build came together easily and others were more difficult. It also reminded me why I don't like using CFE in my own builds; the funky distortions with lighting and wall patterns. Either way, I am pleased with the results.
Please excuse some random holes in the ceiling tiles in some shots. I couldn't seem to fill the holes in even though there ARE floor tiles on the floor above. Deleting and undoing did nothing.
As far as I am aware I have used no CC on this build but I did use quite a bit of Store content.
