Special Buildings i've so far expanded:
Homeless shelter E:2 40 m² - I understand each 20m² expanded on this building provides an extra "task" to complete
Hospital E:1 21 m² - ""
Hall of fame E:1 21 m² - What does expanding this building do, though?
I'm interested because points are a good way to rise in a worthwile ranking in the game, but also keep the amount of "cash" and "fixed assets" you have low, keeping your "level" low and allowing to to maintain a higher level of production

Thanks!
