Could this mean that the bedroom and entry gallery rafters are only 2- 4 x 2" = 200mm which is why Mr Turner installed steel flinch plate on every 2nd rafter ( on 4ft/ 1200 grid)

If this is the case then the bedroom eaves is only stepped once, not twice.
The section drawings of the workspace indicate 8 x 2 rafters.

This photo suggests that the the bottom step in the roof eave for the alcove is also the header for the windows -

and internal showing alcove header over clerestory windows

so maybe the alcove roof is also 2 x 8 framing?

and his photo clearly shows a thin head of the windows in the kitchen relative to the carport ceiling - add in more evidence that the kitchen roof is 2 x 8 framing

entry and kitchen header - also note - internal fascia are almost as same height - using brick courseing as the guide

Getting to feel like the contractor saw these plans and went in his own direction.
2x8 roof joists are not unheard in Wright. Some of the sections SDR posted here show them.

Wonder what is causing the upward curve in the middle of the long roof line above the walkway in this shot.
I see it in a lot of other photographs too.

To me this curving of the fascia coincides with the location of the big steel beam that Mr Turner installed over the kitchen windows (and corresponding parallel rafters) , such that as the carport deflected under its self weight, the tail end of the structural eaves adjacent to the kitchen steel supports bent upwards and then down again to where this fascia joins the normal rafters .

I think this tendency has been exasperated by the the way they constructed the carport roof - in that they put in rafters parallel to this steel beam - not perpendicular to it.

Your sketch section raises the question, "How can members oriented north-south be continuous, if they must cross in the same plane continuous members oriented east-west . . .?"

"Rafters" would normally be members crossing the walls; those parallel to the walls would be---what---purlins ?

that detail sketch I just did is wrong ! sorry for the confusion

I've updated the model to 2 x 8 rafters to the kitchen bedroom and alcove areas., which I think now shows the probable step /window head in the kitchen.

The structural fascia members parallel to the steel beam are doing a lot of work! - approx 4.8 m span from steel to first full length rafter over entry gallery.
here is 3D section near the kitchen - blue is the steel

I was dreaming overnight about all this, and wondered what timber they made the rafters with ?- some lengths are pretty long-

Would have it been douglas fir/oregan- to get such long straight lengths?

SDR is best to respond to your wood question.
The walls of the house were built of redwood according to Elizabeth Halsted the owner who painted them.

Both sketches are good, just taken at different places.

The repair work added steel channels on toop of the wood joists perpendicular and across that big main beam - probably to relieve the pressure on the fascia.
