Yep, as I mentioned, there are a few things missing from this drawing. I didn't draw in the tie beam between those upper rafters, but did realize I need it there. Like it said, it's just rough first sketch and needs refinement and adjustment. Maybe I posted it too early, but I figured you all would want to get an idea of what I was thinking about. I do welcome all of your comments though as I'm sure others will see something I miss.
As far as zoning, don't know the rules yet, but It's going to be out in the country. When I get a design I like in a few weeks, I'll start looking into county building codes etc.
