We want to make architectural theory more tangible by exhibiting it, discussing and presenting it in Karlsruhe's urban space! To this end, we are once again inviting you to the Architekturschaufenster for "AT goes A SF": an evening in which we want to discuss insights, questions and ideas from our courses with students and guests. We move through diverse scales, categories and contexts: we will work on key terms of architectural theory, read critical theory, examine the different scales of architectural objects, examine the culture of bathing facilities, analyse architectures of political decision-making and visit the Federal Court of Justice, and, while "annotating" another study trip live in Italy, we will look into Florentine archives. In doing so, we understand architectural theory as a unifying critical practice – and look forward to a lively exchange!
