Aside from stability, I consider the height the most important aspect of a turning bench - consider that carefully. Turning tends to be unlike many other WWing processes, in that you stand in the same spot for longer periods of time - so ergonomics becomes ever more important. If you and your lovely shop companion are both going to use this... you may need a unique design with variable height, have two benches, or seek a compromise that makes turning uncomfortable for both of you
My bench came as a package with my lathe - purchased from another turner. It is simply a heavy basic bench. THe plans were from Teknatool, the company that produces Nova, and were on their website IIRC; I don't see it anymore.
Looks very similar to this pic/link:

It's built primarily like one would build a real workbench - heavy timbers and stout joints. It has with an edged plywood top, and a lower shelf box that can be used for ballast (which I have not used). The area between the shelves in open, but filled with turning blanks I may never get to.
I see no reason to not make this area have a set of drawers to store the many turning related items you will accumulate. This will undoubtedly include Klingspor's 'by the pound' (buy the pounds!) GOLD sandpaper that is unmatched for turning usage and a few other items that you will find you 'need'. If no drawers then you will want to have another storage area nearby for related tools and supplies. I personally would not store turning tools (the chisels) there, as I find I do switch to another tool reasonably frequently, but chucks, spur drives, base plates, ....
Hope that helps
