Describe symbolism in The Writing Life by Annie Dillard

The study in which the author currently works (at least at the time of this book's creation) is a small, isolated building separate from the rest of her house. As such, it is a clear symbol of her intent/desire/belief that a writer needs physical, emotional, and spiritual isolation in order to write - that is, in order to focus fully on the world emerging from her inner source of creativity.
