If you want to diy, then I would put a rod across the top and shelves at the bottom around the three sides. I think you also could go to one of the big box stores and ask them what you would need to organize a closet...take the size of your closet and what you want to put in it.

Do you want to store the coats hangers or on hooks? Will the coat storage be out-of-season stuff, or accessed every day?

Will the shoe storage be daily shoes, or the sports/winter footwear?

Shelves on the left. Some bins on them for storage of loose items. A hook system (like pegboard or something more modern) on the right can hold bats, rackets, hockey sticks, and more.

Wow a pegboard is a neat idea To hang sports stuff! This would be an everyday use closet, almost to function like a mud room. Everyday shoes and coats. Thinking a rod or something similar. Thanks for the advice!!

Could you go with a hanging rack ON WHEELS? Coat on top /shelf for sports stuff underneath. That would allow you to keep coats, etc. towards the front (or in the middle, depending upon your dimensions) and you could have seasonal storage BEHIND the wheeled unit?

I also like the pegboard idea.

That’s a smart idea to utilize the back of the closet and keep the everyday used items toward the front! Thanks!!
