Hello!
Need some help thinking about my cabin frame.
I have a 10 wide x 12 long main room with a 8' overhang in front to serve as a sleeping loft. this makes the roof line 20' long.
The problem is that we wanted more room in the loft, so we built a 2' pony wall on top of the 8' wall to raise the roof up a bit. I am concerned that we don't have a good way to support that pony wall. Basically, I think that when you put the roof on up, it will want to act as a hinge. Any ideas on how to support that without making it look terrible? The good way would have been to frame the walls up to 10', but it's too late for that now. Ha. Thanks!

Where is this at? What kind of snow loads and wind loads do you expect? I realize it is still under construction but the front end of the overhang isn't supported very well right now.

Yeah, that bracing is temporary and we have a plan to support the front.
It's in Southern Trinity County in Northern California. I could not find snow load info right away (Zip Code 95552), but the area rarely gets over a couple inches. Thanks!

You'd probably be fine with collar ties. However, installing posts in the center of either end of the cabin with a properly sized ridge beam would be better.

That's actually a rafter thrust rather than a shear problem, for whatever a name is worth. The rafter ties would need to be in the lower third of rafter height to do the job... would kind of ruin the loft. You really need a ridgebeam that is directly supported by posts to the footings. Size depends on span between support posts (3 if possible in 20') and snow load.
