Buildings are constructed and upgraded within the City View by tapping on an empty square. Every building costs resources to build and takes a certain amount of time to construct.
Buildings can (and should be) upgraded; especially if you witsh to progress further into the game, unlocking new research, additional buildings and buffs. buffs for particular buildings can be seen by tapping on the building itself, and going to “More information”, of you can jsut take a look at the individual buildings below.
Depending on your game’s settings, you can be notified when a buildign can be upgraded by a small yellow/orange arrow, that points up, and is usually found on the from, right side of the building ready to be upgraded. This arrow signifies that you are eligable to upgrade that building, through both resourses and levels. The higher level the upgrade, the more buffs, perks, and general activities and events you can perform, however the construction times can begin to take an extremely long time (Late in game) and many more resources. (You can use Speed Ups to lower your construction time.)
