One corner of my addition project is the location of the “L” shaped stairwell. This means there is only the rim joist available to apparently support the subfloor, and by extension the wall framing.
I’ve searched my manuals for such an occurrance, but can find no explanations for how to properly support the subfloor and upper walls. I think i have an approach, somewhat borrowed from another portion of the project, involving constructing a ‘beam’ using blocks and a second length of joist (half supported on the mudsill, half via a double joist hanger). The same must also be done 90-degrees to this new ‘beam’ to support the remainder of the corner.
Does this sound like the correct approach, or do I need to brace my architect?
