Lockhart’s office is located on the second-floor of Hogwarts castle. The walls are filled with photos of Lockhart; there are even some that are signed (CS7). The photos are brightened by the “light of many candles” in the evenings (CS7). Lockhart has stacks of photographs on his desk, ready to be signed and sent out to his fans. There is “a life-size poster of himself” on the back of the door (CS16). The office also contains trunks, a chest of drawers and a window (CS16).
When Ron and Harry arrive to speak to Lockhart about the Chamber of Secrets, they find Lockhart preparing to leave. Apparently, he is a quick packer.
"His office had been almost completely stripped. Two large trunks stood open on the floor. Robes, jade-green, lilac, midnight blue, had been hastily folded into one of them; books were jumbled untidily into the other. The photographs that had covered the walls were now crammed into boxes on the desk" (CS16).
