Alice Finch spent creating this big, big, BIG(!) replica of not only Hogwarts School for Witchcraft and Wizardly, but several of the rooms as well, such as the Chamber of Secrets, the Potions Room, the hall where the students ate, and even Hagrid's pad. Check out more pictures under the cut. The attention to detail is phenomenal.
