Next up on Rosenbaum should be LivingRoom upper roof framing plan and sections.
Other thoughts: The original house did not have A/C but the addition did I think because these drawings show duct space in the sections.
Second, regarding the structural aspect of Usonian walls - it's helped me to think the the middle core is oriented vertically not horizontally, the outer layers tying it tightly together.
In any case can you blame contractors out in the country in the 30's for walking away from this work.
I think it's interesting to look at these photos in conjunction with seeing the detailed drawings:

Hanna: "Frank Lloyd Wright's Hanna House, The Clients' Report," page71, section drawings with note on core: 7/8"x8" studs at 2'2" o. c.
So at least two Usonian houses were built with solid boards as core, as opposed to plywood.
"The walls will be wood board-walls the same inside as outside -- three thicknesses of boards with paper placed between them, the boards fastened together with screws. These slab-walls of boards -- a kind of plywood construction on a large scale can /will be high in insulating value, be vermin-proof, and practically fireproof."
As for the roof construction, Wright continues, "The roof framing in this instance is laminated of three 2 x 4's in depth making the three offsets seen outside in the eaves of the roof and enabling the roof span of 2 x 12 to be sufficiently pitched without the expense of "building up" the pitches. The middle offset may be left open at the eaves and fitted with flaps used to ventilate the roof spaces in summer . . ."

Excerpts from the same book; first, an interview with project supervisor Gordon Chadwick:
And from an interview with builder/rebuilder Howard Rickert:
That last paragraph is the first description I've read of how the house was wired. I knew the runs went through the ceiling
... but I did not realize the vertical wiring must have been done after the wall cores were erected and before the horizontal boards were in place.
I need to remember to carry to my office my notebook full of old photos (that came with the house) so that I can scan them. There are a couple of photos of the framing being erected, but mostly it's a series of photos taken over the subsequent years. All pretty interesting, nonetheless.
The amazing thing about the internet is that, between eBay and Amazon, you can usually find a used copy of pretty much any book you want - it's how I created my Wright library (somewhere north of 300 titles I'm afraid). If like me, you care more about content than condition, you can often get a weathered but perfectly readable copy of most any book for under $10. Lets you feed the addiction without going broke in the process ...Tom wrote:See, the difficult thing about Wright Chat is that one keeps finding the content of books you don't have but now want to have.
