Emergency is no longer an exception but a governing framework shaping space and life. This research explores 'Architectures of Emergency' as infrastructures that anticipate and prolong crises, embedding urgency into urban planning. Examining flood barriers, crisis centers, and predictive simulations, it contrasts state-led control with grassroots responses that foreground care and collective action. Moving beyond the spectacle of disaster management, it proposes an 'Atlas of Recomposition' to document how communities reclaim space, challenging the technocratic governance of catastrophe and imagining new forms of collective transformation.
