A Gate Like in Harry Potter
This room is not utilized for storage at all, as one might think. It’s more of a hangout spot, most likely for kids. This environment, like the Narnia playroom, is definitely inspired by a narrative, in this case Harry Potter.
Harry is forced to live under the stairs in the novel because his carers refuse to provide him a decent place. That’s why there’s a sign on the door that says “Wizards Only.” It’s a good thing there’s cushy carpeting in there, because otherwise it would be a little claustrophobic.
