The rules are the same as with the #shellchallenge, let your imagination run wild, but don´t touch the walls (you can add them) ! This is a #harrypotter #hogwarts edition. Each floor should represent one of the houses: #gryffindor, #slitherin, #hufflepuff and #ravenclaw. You can ofcourse add classrooms, the great hall and other fun stuff that you can think of. If you decide to do this challenge, please use the hashtag #hogwartshousesshellchallenge so I can see your creations. :-)
