Hogwarts School of Witchcraft & Wizardry
The interest in my Hogwarts and Neuschwanstein floor plans has been quite amazing!  The Department of Urban Development, civil engineers, college architecture professors and students using them for finals projects, high school and junior high school math and science teachers from across the country using them for classwork, artists, 3-D modelers, animators, game designers, model railroad designers, chocolate and ice sculptors, ginger-bread house bakers, and of course, Harry Potter fans from all around the world using them just for creativity and fun!  Watch the first three films with this floor plan in hand, to see if you can follow the characters while at Hogwarts!
