TVK is an international office of architecture and urban design, created by Pierre Alain Trévelo and Antoine Viger-Kohler in Paris in 2003. Trained in Paris and at Harvard, involved in teaching from the outset, they pursue an approach where theory and practice mutually respond to and enrich each other. Through projects, research and writing they have steadily produced a singular œuvre, at once theoreti- cal and built. Their aim is to capture the complexity and the paradoxical character of the contemporary earthly situation, in order to contribute to making it habitable.
