Current trends in architectural practice such as an increased focus on sustainable design, integrated design, and the globalization of architecture are increasing the need for practitioners that are skilled in collaboration. Collaboration fosters innovation and creativity. It is a key operating principle for the 21st century and an important skill that an architecture student must be exposed to. The change in knowledge generation and creative problem solving is transforming education towards collaborative learning forcing architecture and engineering schools to address new course structures with ìcollaborativeî aspect. The work presented in this paper draws its base from collaborative design learning. It describes an international collaborative design studio titled ìInternational Design Studio: Green Transformable Buildingsî conducted between three institutions, Y_ld_z Technical University (YTU)ñIstanbul, University of Twente (TU)-Enschede Engineering Sciences and Industrial Design School, and Architecture Faculty of Sarajevo (AFS).
