Considering that I designed idea 4, it would be harder to build because it's all one building. I need to fix the scale and it would be hard to make it all align ok without ending up like the current campus. 2 is big, but is actually easier to build because it's pieced up.
If I scale my idea up to a usable size, it would be bigger than 2. I voted 2.
Edit: Also, estimating the brick count of each idea. 4 is about the same as the current campus, with the addition of a 3rd floor and a second wing. Adding those onto the current campus count and having each office filled would be around 40-50k bricks. Idea 2, with 2 small buildings, the center tower, the back two buildings, and after scaling it down to only 16x16 grid, it would be roughly around the same as idea 4, if not less.
Edit 2: If you disagree with me, I want an actual reason. And no, "2 is stuff" is not an acceptable reason. And before you say "It's too hard to build" or "It's too big", you're not even building it, and it is the same size as idea 4, only vertical and less dull.
And that's my full input on the subject.
