Nino, while you're still in a rough planning stage of "what goes where", when it comes to building your workbench(s)......Also consider the option to build mobile workbenchs (on castor wheels), you'll never struggle for workbench room and can move the "waiting for parts" machines into another aisle, then wheel them out when needed later on with no struggle.
Mobile benchs are far better then dragging cabinets and boxloads of boards on & off a fixed bench all the time...
You'll find your fixed bench might disappear altogether, or simply be reduced to a small 2 metre long bench for computer, rom burning, board reworks etc.
Food for thought.
