Here's my tiny 17x20 I think I win so far for smallest space besides those without a space at all! It ain't much but its heated and I can work in a comfy 70 degree garage when its 0 outside so I will take it. Many of my hand tools are laid out on the bench currently awaiting a new toolbox after selling my other one due to being out of space.
I have a miter station with a bunch of built in storage below to the left in the first picture as well. I had set up the space for woodworking until I got the 63 now its just a cluttered mess until I find some time to get it organized again.
