If you were turning a (painted and carpeted) attic space into a room for a teen what would you include?
A couple of things - there's a steep staircase up to the room through a hatch, there's a window in the gable end, there's a small amount of eaves storage.
You can stand comfortably in the middle of the room but not at the edges.
It has power, light and a radiator.
It isn't going to be a bedroom except for an occasional guest.
