Ludwig Mies van der Rohe
Each material has its specific characteristics which we must understand if we want to use it. This is no less true of steel and concrete.
Reinforced concrete buildings are by nature skeletal buildings. No noodles nor armoured turrets. A construction of girders that carry the weight, and walls that carry no weight. That is to say, buildings consisting of skin and bones.
It is not architectural achievement that makes the structures of earlier times seem to us so full of significance but the circumstance that antique temples, Roman basilicas, and even the cathedrals of the Middle Ages are not the works of single personalities but creations of entire epochs.
I see in industrialization the central problem of building in our time. If we succeed in carrying out this industrialization, the social, economic, technical, and also artistic problems will be readily solved.
