Given the sleek high-tech look of his buildings. few would associate Jahn with the timeless act of scribbling. He is, however, an obsessive draughtsman for whom drawing is an indispensable activity. Jahn's drawing is fueled through building and his is a practical imagination, one that preys on a particular project's constraints. His flights of fancy are rarely an end in themselves but are almost always related to solving problems. The exhibition will feature thousands of drawings from projects built and unbuilt, from initial sketches to detail drawings of technical specifications, all in a highly innovative layout designed by this internationally acclaimed architect.
