You need craftsman for the design of the castle.
you need the gold gauntlets which can be found inside ganon's castle (but you need the 6 sages to actually get into the castle).
You need to go to the battlehorn castle and there should be some people you need to kill outside the gates after you kill them one of the guards gives you the deed to the castle and tells you where you can get the furnishing for the castle. its a short mission but the castle is amazing so its worth it and there is a secret mission inside the castle as well
