How old is your son? What will be kept in the closet? Are you thinking of putting in a “system”, like elfa or the like?

Double hang it .Two rods, done, one over the other. A version of below depends his age, his clothes, does he nave a dresser.......etc.

He is only 11. He has a dresser in his room and I’m thinking of doing a built in bed with draws underneath.

For my two boys, I did elfa. Double hanging on one side, drawers in the middle, all shelves on the other side.

Double hanging for boys no problem and since so much of their clothing can go in drawers that is a simple solution. That is a tiny closet so really not much else can be done. Where I found we had issues with our boys was all the other stuff they wanted in their rooms , we finally finished our basement for them to have most of that down there.
