I needed somewhere to keep my spices, they took up too much space in my cabinet. My husband used some wood we had and built a frame. He then added shelves and a door. Now I have a spice cabinet. I really like this and it's so convenient. No more hunting spices, they are all in one place.
Your husband did a great job, that looks great! I'm sure you love it, it's very organized.
I purchased two door/wall mountable spice racks at a hardware store and my hubby attached them both to the inside of one pantry door so I could see all my spices at a glance. I don't have nearly as many as you but I love the convenience plus they don't take up any extra space being attached to the pantry door :)
