The concept of n-ground or multi-ground (Superground and Underground) applied to Seoul recalls a new qualitative development which responds to the possibility to superimpose a new dense floor (container and articulator at the same time) in the old infrastructures.
Seoul new qualitative development does not intend to “continue” or “recreate” the traditional city. Nor impose or positionate, transforming it, built machines or objects (re-objectualizing the urban plot), but superimpose a new dense floor (container and articulator at the same time) in the old obsolete infrastructures; that becomes a new Re-Cyting Topos on, inside, in, where and through which develop new/old programs, uses and activities of life and relationship. A new floor able to maintain a programmatic thickness and also become a new type of relief, platform that reveals in length and height, horizontally and vertically at the same time: a new floor capable of merging landscapes, infrastructure and building in a new type of systems/devices variable and adaptable to the current urban and environmental conditions. Obviously the opportunity areas of the old infrastructures (some in operation, others obsolete or in disuse) are revealed as the ideal spaces to support these new floors, real and virtual at the same time.
