Try Dues Mons. It's a massive fortress just south of the Throat of the World that doubles as a player home, so massive it requires a teleportation system. The only way inside is to kill an extremely powerful dragon guarding it and get the key from its corpse. I believe the reason for that being so that a low level player can't access it immediately. Due to it's size, the mod allows you to hire servants, chefs, bards, a butler, and a carriage driver to fill up the place.

If I wasn't playing the Xbox edition and I had to choose a single mod, this would be it.
