INDESEM (International Design Seminar) is a biennale, founded by a group of students in 1964 and reinitiated in 1985 by Herman Hertzberger. The biennale is hosted at the faculty of Architecture and the Built Environment of the Delft University of Technology. INDESEM has had the honor of hosting internationally acclaimed architects such as Aldo van Eyck, Adriaan Geuze, Rem Koolhaas, Wiel Arets, Ben van Berkel, Winy Maas, Daan Roosegaarde, Jean Nouvel, Shigeru Ban, Steven Holl, Greg Lynn, Peter Cook and Renzo Piano, and theorists such as Saskia Sassen, Bruno Latour, Anthony Vidler, Neil Leach and Michael Speaks. The programme of the INDESEM seminar week consists of lectures, excursions and a workshop, all organized around a specific contemporary theme. Every edition of the seminar aims to raise awareness about this theme and its consequences for the architectural practice, in which both faculty and international students embark on an accompanying specifically themed design project. Previous INDESEM editions explored a vast range of themes, such as the role of the presence of Big Data on the physical world (INDESEM 2021, Datascape), the position of the architect in a rapidly changing, connected society (INDESEM 2019, Beyond The Echo Chamber), the impact of emerging digital fabrication technologies on the practice of architecture (INDESEM 2015 - Re.Craft) and the frictions between the different scales in architecture (INDESEM 2013 - Scale Matters). INDESEM also explored the reduced influence of the built environment as a platform for human interaction (INDESEM 2011 - Losing Ground), the architectural perception through senses other than the purely visual (INDESEM 2009 - Point of View), the notion of legacy in architecture (INDESEM 2007 - The Legacy) and the architect's responsibility in geopolitics, and the production and consolidation of power (INDESEM 2005 - A Political Act). The theme of INDESEM.23 will be announced soon!
