Im doing my own construction model of the Pew house.
As there appears to be an absense of any details on how this house was built, Ive' had a make a few considerations myself ( ie if I was detailing/building - what would I do - as a starting point).
I started by mapping out the 1200 grid ( 4ft) then adding the stone parts - to create a base set of locations for the timber parts ( floors, walls roof).
The floor framing in particular is interesting. According to the section drawing above - its taken through near the fire place, there appears to be only 1 steel beam - in line with the stone retaining wall ( to basement) and pier.
parallel to this steel beam, is 300 x 50 (12 x 2)at 600 c's (2 ft c's) floor joists - (according to my books a F11 LVL- 300 joists can span 5.7m single span),
From fire place to end of deck is 8 bays long x 1.2 = 9.6m, too long for timber joists. Therefore I reckon there would have to be a steel beam tangent across the 2 end piers picking up the joist- reducing its span and probably another tangent steel beam on the grid line that aligns with the overhead end of the roof terrace , thus making the joists span about 5.5m .
then another steel beam parallel to joists at the end wall that is supported by the basement /heater room wall.
However this all seems in contrary to the direction of the floor boards, which run parallel with the floor joists - unless there are 2 layers of floor boards tangent to each other, therefore I am now thinking that the building was built differently to that indicated in the section drawing.
Here is the framing based on my guess of section drawing
and here is the framing based on photos
