The stairway was fully enclosed and wasted a lot of space. I cut into the walls to make the spice-rack/whiteboard first, then continued with the overhead storage spaces. Since doors were hard to find, I used picture frames and created collages. Next to the door - and behind the re-set refrigerator, I put a rolling shelf unit. On the other wall, I cut two narrow doors and was able to utilize space under the stairs for pantry storage.
