When my son was home for college, I had him cut the heavy door in half. He has long arms and is able to reach across much easier then I can. Plus he likes to participate in my projects.
I decided which side I wanted my front to be and screwed hinges on the ends for a 90 degree opening.
I found a 1×12 pine board that I had and cut my shelves and attached them with L brackets.
Stand it up and place in a corner spot. There you have it!!
