Buildings not in Springfield

Is there a list of buildings in the game which aren't actually considered part of Springfield?

Buildings of Capital City, Shelbyville, etc are what I'm looking for. I've finally acquired all of the land and I'm going to redo my whole town. But I'm considering making small, separate Shelbyville and CC sections, if i can figure out which buildings should be there.

Alternatively, if you have a section in your town dedicated to these neighboring cities, a pic would be very helpful too.
Thx!
