We re-did the flooring upstairs in order to move our company offices home. I have 2 rooms that I use for sewing that had to be emptied. It was a huge mess and very physically taxing for me, but the end result was good. We brought the shelves home from the office storage room and put them in there so I have lots of storage in the cutting/storage area. I sorted my books and sorted out of a lot that I don't use anymore and took them out of the book shelves, mostly sewing and tailoring books. It's so nice and organized now. The biggest problem I have is finding things. I know where it was before the re-organization but have no idea where I put it. This is one of the reasons I don't reorganize more often. I even have shelves for my car show trophies that used to be in my office!
I would like to warn the OP that I bought a big, older house (built in 1982) twenty-five years ago. I discovered my biggest problem when I had to empty out the closets for the flooring was that I had lots of closets upstairs and I had filled them up! I had so many old clothes (especially dressy clothes) up there that I hadn't worn in years and couldn't get them on anyway, but still had them. Goodwill scored! I found one box of things that I found after my mother died. I'm sure I was just so overwhelmed (she was something of a pack rat) and I just stuffed this last box in the closet. It had been there for over 20 years. When I opened it, I only ended up keeping a handful of old snapshots of my parents. I have no idea why I kept it all that time. So be ware!
