Modern German buildings are mostly concrete blocks/CMUs with concrete subfloors and wood mostly used to carry the roof. But of course that's a somewhat recent development, sometime in the first half of the 20th century. Before that there was a lot of brick with wooden floors, and before that either stone with wooden subfloor or wooden frames filled with clay. Of course this is somewhat region dependent, and wood is definitely making a comeback again
