It is also Olson Kundig’s design as I mentioned in my older posts. 
This is the Exploded Section drawing. It is a kind of combination of section and axonometric drawing. As we did in section drawing, it is cut from the important parts where we want to show its detail. Also, we again hatched cut parts. 
The detail parts were stairs and fireplaces in the Whistler Ski House 🏡. As you can see in the drawing, these parts were shown. There is a difference between these two, to show the stairs, the wall was cut and the wall was hatched. On the other hand, to show the fireplace, it is a mass and the area which was cut was hatched. Also, the most significant thing was the window of the building. Thus, ✏️I drew almost all detail of the windows.
