Even in the real world, some arcitectural decisions are driven by the client ... we were part of a 'team' of designers working on an athlete's dream home. On a normal inspection of the heating system (our part of the project) one of our people saw that they were installing a real stone staircase over a wooden floor ... the structural engineer had no idea that the wooden stair had been changed to stone. You should have seen the custom steel beams and collumns that were added to support the weight of that stair.
Given the mix of rooms, I thought that much of the plan might have been driven by the 'adventure'. As I said before, I have nothing to add to your graphics ... they look flawless to me.
