Turning the corner
It doesn’t occur in the McAlmon apartment, but many of Schindler’s Plaster Skin buildings have two-sided cantilevers, cantilevers that wrap around a corner. Some examples are
Figure 1 Oliver House 1933-1934
front corner above street level garage 1
Figure 2 Buck House 1934
overall front, house on left and apartment on

Figure 4 McAlmon House 1935

As always, Schindler puts the drama up front. These two sided 
cantilevers are at, or on the way to, the front door.
Applied to our sample building, a double cantilever looks like Figures 5 & 6.
The Schindler system applied
To see how this Plaster Skin framing system 1 was applied, I have made a 3D framing model (Figures 2-5) of our sample building, the McAlmon apartment (Figure 1).
This is my best reconstruction using the scans of the McAlmon construction drawings 2, drawings for other Schindler houses of the period, photographs and my experience with wood framing.
