Some other things to keep in mind with Inn/Taverns:
  • If the place severs food, you'll need a kitchen
  • If the place severs ale/wine, you'll need storage
  • Consider the Inn as meeting hall too, do you need banquet rooms
  • Does the help live there too? Do they have better lodgings?
  • Are these "rich" and "poor" quality rooms?

Just some thoughts. Good work though. Looking forward to seeing more!
