I am sure this has been brought up before but its almost impossible to search through thousands of threads on what has been suggested:
I liked the idea of when you build in the science lab that you can increase damage w/ your towers by 10%. There should be a few more spots that have small perks for building inside it.
Examples:
Build at the harbor, extra elemental dmg tower perk or a water elemental or something not sure..
Building in the summer cottage, boosts your armies morale: increase heal/mana regen 2 hp/s or something
Building in the library provides you with 5 books every 5 minutes or whatever is feasable
