Tectonic research : the Wolf, Esters and Lange houses and the monument to Karl Liebknecht and Rosa Luxemburg

In the 1920s, Mies applied his research into domestic space and the relationship between the dwelling and its surroundings to a number of industrialists, including Rhineland entrepreneurs Hermann Lange and Joseph Esters (1928), using exposed brick as his preferred material. He drew his inspiration freely from the buildings of Frank Lloyd Wright, focusing his attention on the refinement of constructive details. With the monument to Karl Liebknecht and Rosa Luxemburg in 1926, he used the expressive resources of brick to shape a powerful, sculptural volume.
