Hello my friend, Superb Workshop, Well done, but for the workbench right against the back wall you can still improve it, on the two widths and the length you can fix a board on the edge to prevent tools or other parts from falling behind the workbench, you let them protrude 50 mm in height, I speak from experience, after a day spent in my workshop you no longer want to pull the bahu and obviously what has fallen behind the workbench you will need to finish the same day or the following day. Comfort is priceless. Best regards Alain from Belgium.
