I have no plans to share.
I just wanted to say two things:
1. I built my own bench**, after spending several months planning. I put a lot of thought into how I would want to use the space, how I would actually use the space with then-current and future equipment, how to efficiently move within the space, and how to design so that I would avoid cluttering the bench (such as putting doors on lower shelves, so the space in front had to remain clear).
Spend some time thinking about what you need, rather than what other people find an adequate compromise.
**(The plans called for a pair of benches, but the build was interrupted by a move. The first bench was never finished beyond simply being usable in the most basic form of the design, and the second bench never made it farther than obtaining the work surface.)

2. If by "working on guns" you mean assembling AR parts kits, swapping parts, mounting scopes, possibly stoning a few parts, etc., then proceed with the shared work space. But if "working on guns" is more along the lines of gunsmithing - altering parts, sanding, filing, shaping and finishing stocks, etc. - then I suggest a separate bench. Keep the mess away from the reloading bench. My first reloading bench was dual purpose. Constantly cleaning the metal shavings and wood detritus so that I could reload became tiresome in short order. Even as fastidious as I was about contaminants on the bench, I still ended up with debris scratching the inside of a couple sizing dies.
Once the reloading bench mentioned above was put into use, the old reloading bench became my work bench. It is constantly covered in metal and wood shavings, abrasives, sharp objects (stabby and cutty things!), and various tools. The two benches are at a 90 degree angle and only about two feet apart - with me sometimes leaning on the reloading bench while working on something clamped in the vise on the work bench - but that's enough to eliminate all of the mess that would otherwise be on my reloading bench, except for airborne sanding dust.
I do, however, typically use the reloading bench for working with "clean" gun parts - or as a surface for laying out gun parts that I do not want near the dirty work bench. That's another perk to having two benches - an area to organize for the task at hand, and another area to work.
