Trees are not only among the largest, oldest, and most complex living organisms on earth, but they also grow exceptionally slowly – often taking decades or even centuries to reach their full size. “Trees, Time, Architecture!” uses historical and current international examples to examine the potentials and contradictions of „building on trees“ in architecture and landscape architecture. The exhibition highlights the contrast between the slow growth of trees and the urgency of finding answers to burning ecological and social questions here and now. Trees, both living and dead, can be understood as a functional building material that characterises the built environment through their material and aesthetic qualities. For the first time, this exhibition project addresses the topics of “Tree, Time, Architecture” from a holistic, multidimensional perspective.
