This interdisciplinary seminar explores how the history of architecture and urbanism can be approached through the lenses of mobility, impermanence, and material flow. Focusing on portable buildings, extractive infrastructures, and construction on unstable terrains, we will rethink the built environment beyond permanence. Participants will engage critically with readings and guest lectures, while developing a writing practice around an "unsettling" museum object of their choice. The course is open to students interested in mobility, mediation, and transience in architectural history, both within and beyond Europe.
