Since this has turned partly into a storage thread....here are a couple other ideas where you can reclaim space by moving things up and out of the way...
While this won't work in places where construction doesn't include exposed joists, anywhere with basements and exposed joists will find this easily done:
Buy or rip some 3/4 x 3/4 stock (nominal 1"), predrill holes for either screws or nails, and affix them to the bottom of the joists as cleats on which "shelving" can rest. I used some scrap plywood in one pic. I also use thinner material like 1/4" pegboard depending on the weight above as well as how close that weight comes to the cleats to support the weight.
Depending on the circumstance I number the little shelves so I can have a list of what's up there and where it is. I'm not storing stuff I need daily, but they're things that take up space nonetheless. Especially bulky items like wads for reloading shotgun shells are perfect for this.
The other pic here I've posted earlier in the thread; it's a rolling set of shelves inspired by storage places such as libraries or where there are a ton of files, such that they have rolling or sliding shelving/filing that butts up against each other. The result is only one aisle, and the shelves/filing cabinets are moved back and forth to create an aisle where you need it.
I needed more shelf space in my basement and I was running out of places to do it. So I built a rolling shelf arrangement that nests against my other brewing equipment. When I need something I just roll it out into the walkway, and I then have access to what's behind as well as on the shelves.
Money-saving suggestion: I never buy swivel casters by themselves; virtually all home-depot and farm store types of places sell furniture dollies that have those casters already on them, for much less than you'd buy those casters individually. I'll either make the rolling shelves directly on the furniture dolly or remove them and reapply. Cheap, easy, and they work.
