Expressionist Architecture - Materials

Materials

A recurring concern of expressionist architects was the use of materials and how they might be poetically expressed. Often, the intention was to unify the materials in a building so as to make it monolithic. The collaboration of Bruno Taut and the utopian poet Paul Scheerbart attempted to address the problems of German society by a doctrine of glass architecture. Such utopianism can be seen in the context of a revolutionary Germany where the tussle between nationalism and socialism had yet to resolve itself. Taut and Scheerbart imagined a society that had freed itself by breaking from past forms and traditions, impelled by an architecture that flooded every building with multicolored light and represented a more promising future. They published texts on this subject and built the Glass Pavilion at the 1914 Werkbund exhibition. Inscribed around the base of the dome were aphoristic sayings about the material, penned by Scheerbart.

"Coloured glass destroys hatred","Without a glass palace life is a burden","Glass brings us a new era, building in brick only does us harm"- Paul Scheerbart, inscriptions on the 1914 Werkbund Glass Pavilion

Another example of expressionist use of monolithic materials was by Erich Mendelsohn at the Einstein Tower. Not to be missed was a pun on the towers namesake, Einstein, and an attempt to make the building out of one stone, Ein stein. Though not cast in one pour of concrete (due to technical difficulties, brick and stucco were used partially) the effect of the building is an expression of the fluidity of concrete before it is cast. 'Architecture of Steel and Concrete' was the title of an 1919 exhibition of Mendelsohn's sketches at Paul Cassirer's gallery in Berlin.

Brick was used in a similar fashion to express the inherent nature of the material. Josef Franke produced some characteristic expressionist churches in the Ruhrgebiet in the 1920s. Bruno Taut used brick as a way to show mass and repetition in his Berlin Housing Estate "Legien-Stadt". In the same way as their Arts and Crafts movement predecessors, to expressionist architects, populism, naturalism, and according to Pehnt "Moral and sometimes even irrational arguments were adduced in favor of building in brick". With its color and pointillist like visual increment, brick became to expressionism what stucco later became to the international style.
