How does one make buildings regional?

[TotalDonutWar]

As the title says, how do you make a building regional? For example, the building "Reiksfort" can only be created in the province Reikland. I want to create new buildings which are only available in one specific province but I don't know how. Help is much appreciated

Don't know if you still need help on this but this post should help you out a lot.
