    But all the good buildings are concrete and steel! The combustible architecture is for peasants only

      As an engineer i can tell you that a building being made of concrete and steel in no way indicates it to be safeguarded against fire. With how combustible a lot of interior has become over the past century, it can still turn into a flame engulfed hellhole, unless a high level of fire protection was achieved with proper firewalls and seals, containment design, extinguishing measures etc.

      If you subject steel directly or rebar concrete to heat for a long time, the structural integrity will be permanently lowered, often requiring a building to be demolished and rebuilt after a larger fire.
