This lecture follows Alexandre REBOND, an architecture student at EPFL, as he explains the collaborative process between students from EWHA University in Seoul and EPFL in Lausanne to repurpose a 2.7 km underground gallery in Seoul. Starting with a conceptual approach, they developed and integrated their ideas into a simplified tunnel structure, eventually transforming the existing underground gallery into a new space for interventions. Dividing the gallery into 27 sections, each group of students incorporated their own programs, resulting in a collaborative 'Wire Frame' model displayed as a bench installation in Seoul.
