Leavesden wasn't just a set; it was a home. For over a decade, the cast and crew lived and worked here. Because Warner Bros. owned the space, they didn't have to strike (tear down) sets between films. This allowed the Gryffindor Common Room and Dumbledore’s office to remain standing for ten years, gathering a "lived-in" detail that CGI simply couldn't replicate.
