After Mies van der Rohe had moved from Berlin to Chicago in 1938 to head the architecture school of the Illinois Institute of Technology (IIT), his approach expanded beyond paradigmatic new solutions for a range of building types – from skyscrapers to country houses – towards an emphasis on the design of structural details – not necessarily optimizing their functionality, but rather creating an expressive, photogenic, carefully proportioned appearance – inspired, but not limited, by their structural and material qualities. Corners were the most poignant locations of these interventions, which he considered ›universal solutions,‹ applicable again and again with only small variations. Several buildings on the campus of IIT, high-rises for apartments and offices, as well as numerous mid-size office and educational buildings illustrate the evolution of this approach.
