My shop space is limited to a narrow strip down one side of the garage from the side door to the corner where my workbench is. The back wall is off the foundation, but the roof doesn't leak (anymore).
First pic, from outside the overhead door looking in.
Second, this is about all the open space I have, but it's not bad. If the weather's good I can move the trailer out, and another bike to make space. The black mats on the floor are from semi-trailers (they sometimes put pallets on them so loads won't slide).
Third, my workbench corner.
Fourth pic.. I bent some 1/4" dia. rod into S-hooks to get rims and tires out of the way.
Last pic, the workbench again. At the top you can see one of my Uniden system cameras (just to the left of the tires). That one sees everything from the doors back to the bench. It also lets the wife check on me or see if I'm home from work.
Another one on the side of the garage sees my car and the side door area.
