The competition, organized by ConstruirAcier, is open to students, alone or in teams, at architecture or engineering schools in 2025-2026.

Topic 2026: “Reversible(s) – Building for transformation

The 2026 edition of the competition asks entrants to design a double-life space, capable of adapting to changing uses or contexts. Whether it’s a building, mobile equipment or a modular structure, the project must demonstrate how steel architecture can be designed to evolve over time, be easily dismantled and reused, with no loss of performance or quality.

Applicants should pay particular attention to :

  • imagine a reversible and dismountable construction system or assembly, based mainly on steel;
  • design a dual-use or programmed mutation project, designed from the outset to be transformed, moved or reused;
  • incorporate in-depth consideration of environmental performance (low carbon impact, reuse of components, life cycle);
  • to propose an assertive architecture, both in its initial use and in its transformation.
