"In our day and age, I see the central issue of building in the industrialization of construction," and this process "is a question of materials", Mies van der Rohe wrote in 1924. With these words, he was formulating a question that Hugo Junkers had already resolved for aircraft construction ten years earlier. In contrast to standard practice in those days, Junkers did not build with wood, a natural material that was unpredictable from an engineer's point of view. Instead, he opted systematically for aeroplanes made entirely of metal.
