Hey yo jay, did I ever send you the drawings for the barns I will build this fall?

As for this design, looks straightforward, simple, not much going on that would cause concern. The ridge is directly posted to the ground, that's good and simplifies the tie joinery -you wan't have outward thrust, actually those principle rafters sticking past will push IN on the walls.

What kind of roof covering will you use? I myself am a fan of common rafters rather than common purlins, but that's just my background. Id use those posts to support big heavy purlins and hang rafter from them. Then the frame would really be the prototypical west Germanic frame.
