A single plane, folded many times without a break. The ribbon rises from the ground, bends along the diagonal and leads upwards: every fold is at once the edge of one space and the beginning of the next.

The plane is the primary structure. The folds span several storeys, and volume appears in the spaces between the bends. A secondary structure fills them: intermediate slabs, glass, the core. The infill may change; the ribbon stays.

Sketch – form – building. The same line in three states: set down by hand, drawn out as a sculpture, set into the city as a model. Each stage adds layers, and the line stays the same.

One line, drawn without lifting the pencil: flow, continuity, continuation.
