What can we learn from the damage? Is there a design flaw?
What you see in the picture above, is only a small portion of the building, 1/4 of it maybe? It keeps going for a long time, where you see the burned out porches, also likely the apartments where the fire started at first glance, it was the most damaged area and appears to be the hottest point.
The photo ends but on the other side, the building bends again into another corner to an additional wing/leg of the building where the fire also spread very quickly.
