The first and last sentences of the "Founding a Kingdom" section of the kingdom building rules read:
Founding a Kingdom section wrote:
Once you have your first settlement, you have the start of a kingdom.
Founding a Kingdom section wrote:
Once you’ve completed these steps, move on to Kingdom Turn Sequence.
This implies to me that you don't start the kingdom building rules until after your first settlement. It's assumed that the hex for your first settlement is sufficiently prepared to have a settlement.
In other words, first you have your initial settlement, and then you begin the kingdom building rules, where you can start adding buildings during Step 5 of the Edict Phase.
