If you want to upgrade your building in the camp, always check if you meet the requirements for the upgrade.
Buildings always require you to have:
- a certain player level
- a certain Council level
- a certain amount of resources available in storage
Tap on the building you want to upgrade and then tap on the information button, shown as "i". This will bring up the information window and state the requirements for upgrading this particular building.
