How tall are you? Are you planning to use loading stands to raise your presses? Are you going to build this yourself or hire it out? Are you going to do all your loading standing, sitting or some of each? Adding bullet feeders? What about tumbling? If so, in the same room or somewhere else?
Important to know the slope of the roof.....I see the 58" off the floor, how high is it off the floor 12 or 24" out? Be glad to help with scaled drawings, even 3d, but I need more measurements, with a tape, preferably not counting squares....too much chance for mistakes.
I've attached a PDF file that has a very stout yet inexpensive (material wise) way of building benchwork for you to check out and use if you like the idea. The last pictures are of my bench. I used formica for the top and used the extra piece in front instead of matching wood.....I still may remove that and replace the front piece with wood to make it look richer. ;)
