American architect Lebbeus Woods was commissioned to create these drawings for an exhibition about Berlin’s future. Made in 1988, one year before the fall of the Berlin Wall, his proposal activates an old railway tunnel that crosses the border between East and West Berlin. Woods saw Underground Berlin as a network of passageways, chambers, and suspended structures. His drawings meld reality with cinematic imagination and suggest the possibility of unification below ground. For Woods, drawing and building are equally important as ways of investigating urban context.
