We had just wire shelving in our closet for years. Big room over the garage, but completely disorganized with shoes in boxes stacked (so when you needed the one on the bottom the whole mess fell over). Sweaters piled on wire shelves, hanging items just jammed together. Had our contractor custom build based on our measurements for linear space needed for hanging items, and drawers needed for folded stuff. Sweaters and Jeans folded on shelves. Counted shoes, and figured out how much shelving I'd need for them (hint: it's never enough!). Shelves are all adjustable. Had sloped walls on 2 sides so accounted for that with shelves for bags etc and to maximize usable space. Also added an island for temporary storage and drawers for things like jewelry, scarves, belts etc. In-rod lighting is key! Also puck lighting to highlight items on shelves. A nice light fixture can dress up any area. It's not just better organized, it's a pleasure to walk in there and figure out what to wear vs. being stressed with a messy or uninspiring space.
End result is much more organized, with much fewer items, because when we hauled everything out to remodel we only kept out what was in regular rotation. Realized I didn't need at least 50% of what I had! Also having things visible and organized makes things more usable. (Look! new closet saves us $ in the end! lols....)
I do have to say that sliding door indoor/outdoor space you have going in is the bomb!!!
