About twice as high but incredibly larger. Hausmannian buildings have at most six stories which, IMO, is already one or two too many. But really Hausmann's style is elaborated, not brutalist.

Another complete afterthought is the gigantic shadow these monsters do cast. In some cities they brought entire neighbourhoods into shadow during the day.

Such buildings are just sad and reflect the minds of their creators (and of those who rooted/root for them).
