I tried it that way once and liked it, but felt it narrowed the aisles too much. It makes them less than 24" all the way around and that depends on whether or not Mark expands the decking to the full 30". Here's what it would look like with the decking at 30". I certainly think it looks better, but the original orientation has 2 larger areas for moving around. I would probably build it this way, but I'd probably operate from the entrance and only use the aisles to fix problems.
I also like Mark's idea to make it mobile, so it could be moved out of the way for maintenance and landscape work.
