With the stairway framing sheathed in plywood, today I turned my attention to creating storage space under the stairs. I installed shelving in the pockets under each stair creating both shallow and very deep storage areas. I left an opening at the front to fit a shelving unit on casters. I will store my most frequently accessed items on the shelving unit and roll it out of the way to get at less often used items on the built-in shelves.
