Hidden Cities: Reinventing The Non-Space Between Street And Subway Abstract The connections leading to underground transit lines have not received the attention given to public spaces above ground. Considered to be merely infrastructure, the design and planning of these underground passageways has been dominated by engineering and capital investment principles, with little attention to place-making. This underground transportation area, often dismissed as “non-space,” is a by-product of high-density transit-oriented development, and becomes increasingly valuable and complex as cities become larger and denser. This dissertation explores the design of five of these hidden cities where there has been a serious effort to make them into desirable public spaces. Over thirty-two million urbanites navigate these underground labyrinths in New York City, Hong Kong, London, Moscow, and Paris every day. These in-between spaces have evolved from simple stairwells to networked corridors, to transit concourses, to transit malls, and to the financial engines for affordable public transit.
