It's a pass thru, so I don't think you can do much more than what you've already done.

I think a carpenter can put a hanging pole in one of the slanted crawl spaces...he will have to put something to fasten the pole in. In the other one, I think he can put shelves in.....or maybe you could find a shelving unit that will fit in that space. Don't have to change the doors at all.

Does that space go all the way through from door to door? Looks like a lot of good storage. Just have a carpenter or DIY to make it easy to hang and store. My MIL had a crawl space in her upstairs room and had shelves in there and lots of plastic bins for storage.

Since the 2 doors are a different size, I would recommend to add some visual balance the the wall. Some interesting sliding doors could be a great option. That way the door on the right side could visually match the width of the door on the left. Once it’s done, than you could place some narrow sofa/foyer type of side tables and display your family photos or other accessories. That part will depend on the purpose of the space. Hope this helps!

Thanks, I love that idea!
