I got my plumber over and relocated the pipe that normally went straight up from the blue water pressure tank, see earlier shots and you'll easily find it. This opened up a whole new vista! While I was originally going to just extend a bit to the tank, I realized I could grab that whole area and put a fascia to hide the tank, plus make the grain elevator look massive. In this view the new plywood, with hole cut out for the top of the tank, is in place.
