Grenfell Tower in the UK was made out of concrete. Burning exterior cladding killed 72 people: https://en.wikipedia.org/wiki/Grenfell_Tower_fire

depends on where you are in the EU I think, UK and Ireland still use piles of blocks but no shortage of wood houses in Europe. There's a whole industry of building woodframe houses in the Baltics and shipping them around Europe, incidentally.

Brick houses still burn; interior walls, floors, ceilings, and furnishings are still made from wood or other flammable materials. There have been plenty of castles that caught fire, despite their stone walls.
