The Seminarkurs Gefundene Gegenstände (Reuse in Architecture) invites to collectively reflect on how we can combine Reuse, Recycling and other circular strategies with more ambitious cultural goals that are firmly rooted in the history of architecture. By adding diverse notions like ready-made, as-found, objet-trouvé, copy, sample, appropriation or decontextualization these ecologically sustainable processes resonate with other contemporary cultural practices. At the same time, they also reflect on the fusion between production and consumption.Architects could make work from pre-existing materials: that is, generate meaning from a selection and combination of heterogeneous components already given. The notion of originality and creation is blurred in this new cultural panorama in which the figure of the dj, the programmer or the curator stand out, whose task is to select components, materials or objects and insert them into a new context. During the semester, we will together research, discover and document diverse historical precedents of ready-mades in architectural projects.
