“Dead space” in a finished attic can be used in many creative ways. Here are a few ideas: finish out an area as a chest of drawers, build bookcases into the space, build storage shelves for children’s toys and games, build cabinets into the space for most any kind of storage, build in a desk or computer table, make a nook for a table or a shelf for displaying items. You can also leave the inner space as free of obstruction as possible and fit it out with shelves on one side or compartments accessible through a low door.
