The door is closed and locked though the professor is in. Once you knock the professor will allow you to enter. The walls are lined with bookshelves, but on them no books. There are various rare ingredients in jars and bottles. A desk and a chair behind it, books and papers on the desk. There is a workstation with a pyrex cauldron on a burner. There is always something burning. A very uncomfortable chair is set in front of the desk. This makes it hard for a student to spend too much time in her office.
