The oak door opens into a large and beautiful circular room with windows, at least on of which faces east with a view of some of the mountains surrounding the castle. The walls of the office are covered with portraits of previous Headmasters and Headmistress. The wall immediately behind the Headmasters desk has a shelf holding the Sorting Hat.

The Headmaster's desk is enormous, claw-footed affair that apparently goes with the room. The surface is highly polished, though naturally it is sometimes covered with papers. The Headmaster also kept a silver pot with a handsome scarlet quill on the desk. The desk faces the door leading up from the gargoyle; a visitor standing with his back to the Headmaster's chair will find himself or herself staring out at the Quidditch pitch. The Headmaster keeps a visitor's chair but sometimes conjure more when several visitors arrive suddenly.
