harry potter - Is there an official blueprint of Hogwarts?

J.K. Rowling drew a basic layout of Hogwarts and its surrounding grounds:

I will see if I can find any other drawings having to do with Hogwarts specifically. I think the movies are really wonderful, and they have J.K. Rowling's input and approval, so using ideas from the movies should be within the spirit of canon, if not perfectly, technically canon. Sachin Shekhar has already mentioned the Order of the Phoenix video game; make sure you get another source or two verifying the game is based on official movie blueprints, as most movies have only partial sets and a lot of the Harry Potter movies are filmed in front of the green screen. Enjoy building Hogwarts!
