Ladder Framing for Roof Outriggers 5

Hey Guys,

I'm trying to frame some outriggers in a wood residential building. See below for what I've initially drawn trying to use a ladder framing approach. the light blue are typ. TJI's. The red are beams and the green are where I can locate posts. There are openings below these beams so there's no wall or posts that can be added. I think the main issue I'm running into is framing the corners of the outriggers. I end up with 2 cantilevered beams and I'm trying to think how we can get around that. Do you guys think my drawing looks reasonable? Should I just have them do steel beams instead even though this is residential? Do you have any ideas on the corners?

Thank you!LADDER FRAMING.jpg

There are so many colored lines on your drawing that I don't really know what's going on. But I borrowed your drawing and added an angled blue line. I could cantilever over the corner of the building and pick load from the fascia boards. You'd have some connections to figure out, and you'd need structural sub-fascia. But it should work.

@rwpe thanks for the response and idea. just confirming you were using that to support the rim beams correct?
 
If I understand correctly that your only vertical supports are the green squares, good luck! This architect is a menace. How do you plan to have any lateral resistance?

Not sure there's any hope for the bottom left corner without this being a diving board.
