   I'll give you an answer that will mainly serve to keep your question from dropping off the bottom of the list of topics.

   Have you considered angled support brackets (like shelf supports, going back to the wall, or better yet, the foundation, at an angle)? If I were doing it, I would then enclose the lower part with siding so I could insulate it, and keep bugs out. Maybe others can give you better answers.

   I thought about tying it into the wall as you suggest however the wall is all weather wood with bituthene and foam. It goes down to the footer about 6' below grade. Fear is that tying into the header for support might cause twisting.

   Oh, I was thinking the foundation was concrete or blocks and was slightly above grade. Well, in the case you describe, I don't see much wrong with your idea. I see you didn't get lots of responses. Maybe my reply will stir things up.

   I guess I don't understand what you want?

   For obvious esthetics I think I need to built it out to match the bumpout above. Do I make a small "floor" with joists as support across the bottom? I guess I don't know the standard framing for this type of thing. I don't see an example in my Taunton framing book. (great reference) Thanks for the input

   It's not a framing solution.

   Build a concrete pad under there with proper footings and then frame on top of that like you would a a slab.  Depth of footing's is determined by local codes and soil bearing capacity.  The wall framed on top of the slab will support the bay above.  You may have to dig deep to get past backfill and into stable soil for the footings to rest on.  Look out for a perimeter drain on the way down. 

   You don't want to frame a floor at ground level, if that's what you're talking about.

   I think he already answered that in another post.  He is going to put in sonatubes  to hold it up.

   To answer his question, I would frame on top of the base with floor etc.

   well then maybe I'm misunderstanding.  Is he going to extend the walls down to grade or..?

   Above grade set on 4x4, I believe.

   You can see there is a bit of a dip where the window used to be...tended to attract water. I plan to fill that level with the rest to encourage drainage away from the house. I'll be framing it up this weekend. Lets hope the windows I ordered will fit!Thanks for the help!
