What would be a good Harry Potter-related nickname for a house?

Three of my male friends and I are moving into a house together this summer, and we're trying to come up with a catchy name for the house. We're all pretty big Harry Potter fans, so I was hoping for something related to that. So far, my ideas have been "The Chamber of Secretion" and "The Four Broomsticks." If any of you have any other ideas, please contribute. We'd also accept any equally nerdy movie, book, or video game references. Thanks!
