Wintersemester 2025/26
TU Berlin, FG ArchitekturtheorieSeminar Typologies of Transformation
In contemporary architectural discourse, the imperative of Umbau—encompassing adaptive reuse, continual transformation, and the act of building upon the built—fundamentally challenges inherited notions of architectural production and authorial invention. In this intensive one-week seminar, Professor Andreas Lechner explores the evolving relationship between architectural craftsmanship and the strategies of transformation. Drawing from his recent publication, Architectural Affordances – Typologies of Umbau (2025), Lechner articulates ‘Umbau’ as a sophisticated mode of architectural thinking and making—one that exceeds mere technical renovation and engages in a nuanced dialogue with typology, historical continuity, and material articulation.
Structured around theoretical inquiry, typological analysis, and drawing-based research, the seminar invites participants to identify and interpret the latent spatial potentials—architectural affordances—embedded in existing structures. These affordances, understood as both ecological and cultural prompts, offer new ways of engaging with the resilience, adaptability, and social intelligence of the built environment. Through critical readings and case studies, students will examine the dialectics of permanence and transformation, of memory and reinvention, ultimately reframing Umbau not simply as a subset of practice but as architecture’s disciplinary core—at once critical praxis and artistic endeavor.
This concentrated exploration aims to equip participants with refined conceptual tools and spatial literacy, enabling a more ethically attuned and ecologically responsive engagement with the architectural heritage. In doing so, the seminar advances Um-Bau-Kunst as a necessary and vital architectural response to the entangled cultural, environmental, and societal challenges of our time.
