Far Harbor has it’s own settlements and a bunch of new stuff to scrap and build. I’ve added mostly generous, sometimes ridiculously so, components from scrap and massive reductions in settlement-related building items. Look for super bonus on certain flags.

Modder’s Note: If you are using Homemaker, there is an update, so you can see both that mod’s content and all the new build items for Far Harbor in your workbench UI. I didn’t realize how limited my build menu was myself until I fixed this on my game.
