I agree with John McKean from personal experience.
I remained in the safety of my own home as instructed by the fire brigade on the 24th floor of a single-stair tower in the East End while a flat three floors below became an inferno and eventually burnt out. Having said that, the fire was on the opposite side of the block to my flat, and the fire brigade did evacuate all flats above the fire source.
However, many other residents did behave more 'intuitively' and take the escape stair and quit the building until the fire was out.
Poor design 'contributed to six deaths' did it ?
Well - this is pure speculation and heresay: not 'news' as such.
Would it not be better to with-hold opining and await a more considered opinion based on proper evidence?
We have quite enough hating on architects and architecture without this kind of speculative article putting fuel on the fire and then fanning it so to speak. Bad choice of words I know...
