The theme of the Master Studio of architecturaltheory.eu in the Summer Semester of 2021 is “Goodbye to Language” and will be taught by Eleni Boutsika-Palles and Bart Lootsma. We will make a series of films tracing aspects of architecture that cannot be expressed in drawings or language. And even though we will start the semester with extensive reading sessions, the final goal will be to show or suggest those aspects, as in a silent movie, the registration of a gesture, pantomime, dance, performance, sound piece or the like. Different from regular architectural designs, that are almost inevitably caught up in good intentions or even obliged to positive rationality, these discoveries might also point at dark, negative or uncanny aspects of architecture.
