Loosely organized, I can find almost everything.
Ziploc bags are used a lot, and everything is in some kind of box, not labeled.
Wheels are in bags in a closet. Components for an intended build get a new box.
Every frame hangs, every complete bike hangs. Milk crates hold some stuff.
I do tend to keep things I won't be using all in the same box.

I like my garage. No one else hangs out there except bike people.
If it takes a while to find something, it just does.
I often find bonus stuff I forgot I had. Simple pleasures, yes.
