We need buildings, lots and lots of buildings. City type, not like LOOT but instead more simple OR complicated.
Simple = more real looking but no inside.
Complicated = Realistically formed internals, parking garages are a great example of this.
This means that a variety of people can work on these, since skill varies from a box with a nice texture to a complex multilevel interior structure. Now this is the future, so be advanced. Older buildings will still be around nut less and less common the closer the the center of the capital.
