‘Trees, Time, Architecture!’ explores the potential and contradictions of ‘building on trees’ in architecture and landscape architecture. For the first time, an exhibition project addresses the topic area of trees, time, and architecture from a holistic, multidimensional perspective. Concrete project examples from diverse cultural contexts and climatic zones demonstrate the need for a fundamental paradigm shift: moving away from designing finished objects and towards designing processes to foster a fruitful and sustainable relationship between trees and buildings.
