I’ve actually tried all around bench access in my 12x12 workspace. It’s
doable for a specific project, which initially was the workbench itself!
4x4 doug fir, with small scale timber framed trestles. The bench got
dragged, pushed and levered to the middle of the floor when the sill on the
south wall rotted out and needed replacing, along with the window over the
bench.
You get good at sucking in your gut as you squeeze through the narrow
spaces at each end, sometimes it's easier to climb over.
