The kingdom was centered on Caer Bedris in Builth, in modern Powys. It was apparently founded as an offshoot of Powys by the Powysian Vortigern's son. Apparently his claim was confirmed by Ambrosius Aurelianus after Vortigern's death.

The sub-kingdom or region of Gwerthrynion was part of Builth's territory, and the kings often seem to bear the title king of Guorthegirnaim (Gwerthrynion).
