Hall
The Hall of Order, Sacred Hall and Wilderhall are the primary buildings of their respective factions in Call of Dragons. The hall must always be upgraded first before any other building can be upgraded to the same level. It determines legion size and legion dispatch count which both increase as you level it up. Also as you increase the level, more buildings will become unlocked. The level also determines how many resource buildings and hospitals your city can have as well as determining which troop buildings you will have available.
Storehouse
The storehouse is used to protect resources. The higher the level of the storehouse the higher the base rate of resources protected. On top of that you also get a percentage of your resources protected past the base rate. This starts from 20% at level 1 all the way to 35% at level 25.
