As I was building my Simulated Nanite Factories, I was thinking about how the nanotechnology could maybe see a use for shrinking buildings down in order to fit more production into my cities. For that idea, I was thinking that the dimensions of the buildings that are divisible be shrunk down at the cost of Nanites and higher construction cost. However, if this idea doesn't work, then I am open to other suggestions about new Nanite uses.
