It is already a small building, therefore the conservation of space would be on my list of things to keep in mind. Now, there is the issue of the short cantilevered joist ending in open space, unused space, so it may not be important.

I must just be a simpleton. Let's see, 7 more pieces, that is 14 more joints, times the 3 bents, that is 42 more joints. Or up size the post?

Not that I am knocking DL's sketch, I think it is a reasonable idea, and on a larger building it would be very reasonable. But the topic at hand is only 14' wide.
