Vancouver

Personally I tend to be hesitant on relaxing the duel means of egres rule completely when i’ve seen buildings in Vancouver use two sets of stairs interwoven in the same stairwell to achieve the same effect with only a 30% or so increase in floor space. Even if it’s statistically not much help knowing there are two ways out of the building in an emergency does have an advantage, and i’m not convinced that it’s actually as much of a factor into the proliferation of double stacked corridors as them just being the cheapest way build.

Otherwise i’m definitely a big fan of the suggestions, especially more interconnections between buildings.
