In the fourth episode of GSAPP Conversations, 3rd-year Master of Architecture student Ayesha Ghosh speaks with Swiss architect Christian Kerez, who delivered the opening lecture of Columbia GSAPP’s Spring 2017 Semester. Kerez’s recent projects include Incidental Space at the Swiss Pavillion of the 2016 Venice Architecture Biennale, an amorphous structure which raised questions of the limits of imagination and technical feasibility in architecture today.
