Contamination “is the place of what is sick, confused, monstrous, wrong, unthinkable, especially impure” and partial. The time and the life, the reopening of a built work and the unfinished or the unexpected are possibilities of another fulfilment. Assuming contamination as a process, it “makes a writing not close within the limits of the ability to repeat its structure and its own formative mode”. Attacked by the virus, architecture takes responsibility for recognizing and interpreting heterogeneity, of tying harmonies, of revealing dissonances. It is a “re-generative process”, a practice of the project that becomes aware of reality and, inventing it by figures, tries to return it habitable and projected to the future.
