IBA’27 Festivals of experimental and temporary architecture are planned for the years 2023, 2025 and 2027. The festivals will give insights into methods, projects and ideas ahead of the presentation year and offer a platform for discussions, presentations and experiments. Their buildings will demonstrate the unique competency in serial and lightweight construction in the Stuttgart Region. They will show digitally integrated planning processes and experiment with new building materials, energy concepts and building techniques. They should serve as a playing and experimentation field for students and researchers, creatives and practitioners and provide low-threshold access to IBA’27.
