Have you checked the Main Goal Guide in The Hub?

It lists all the goals from the very start. Maybe you can figure out where you are in the story line & what's coming up next.
What goals do you have in your goal book?

You are able to build a castle (2 to choose from) once you have a workshop. the goal for it comes up quite close to the beginning of the game, so you should get it soon.
