The Viennese architects Wolf Prix and Helmut Swiczinsky, aka Coop Himmelb(l)au, made their reputation on blind, gestural sketches that, sometimes, became buildings. These sketches accomplish many things, three that I would like to focus on: capture a feeling, create a unique design process, and lead to complex structural and design solutions. The accompanying images are Coop Himmelb(l)au's design of a rooftop addition, focusing on a conference room, to a law firm's office.
