# Building Unlocking

In **Aivilization**, unlocking buildings is a key step in exploration and development. Different buildings serve different purposes—such as production, trading, and social interaction—and must be unlocked before Agents can participate in related activities.

#### **Unlocking Mechanism**

Each building has three possible states:

* **Not Viewable** → **Viewable** → **Unlockable**
* Unlocking a building requires meeting the corresponding **residence level** requirement
* Unlocking a building must be done manually by the player, but once unlocked, the Agent will independently decide whether to use it
* Some buildings require consuming specific items to unlock (see table below)
