Panel Discussion


The Chair of Housing and Design at RWTH Aachen University invites you to a discussion and exchange of experiences on collective design, authorship, participatory planning tools, and contemporary processes in architecture as part of a joint research project with the housing cooperative KOOPERATIVE GROSSSTADT eG.
Competitive vs. cooperative, smart vs. nerve-racking, smart vs. dumb, complicated vs. simple, old vs. new, agile vs. linear methods are to be discussed under the goal, which sounds as serious as it does dangerously like a platitude, of finding the best architecture to be adopted in each case for our not exactly small problems of the present.

Moderated by Reem Almannai and Florian Fischer on Wednesday, 28.06.2023 at the RWTH Aachen in the lecture hall R5 from 18:45 clock, Verena von Beckerath, Anne-Julchen Bernhardt, Christian Inderbitzin and Jan de Vylder will share their experiences and views from their perspective of planning, moderating, judging and teaching.

The point of departure and the subject of the discussion is the OP-OD method, which has been used for the first time in the metso 'metso building project in Munich. It combines aspects of real-time participation with open architectural processes. The housing cooperative KOOPERATIVE GROSSSTADT eG has developed the OP-OD method based on its practical experience with the open competition procedures for San Riemo and Freihampton. The acronym stands for Open Plan Open Decision. Similar to open source applications in other disciplines, it aims to enable collective planning and authorship by all project participants, including users, to deliver more efficient and sustainable building designs.

Verena von Beckerath, Anne-Julchen Bernhardt, Christian Inderbitzin and Jan de Vylder have intensively accompanied the first two open competitions of the cooperative as jurors and have also viewed them very critically in some cases. At the same time, they draw on their own practice and teaching from a variety of collective design processes and specific design methods of their own. The spectrum of the four interlocutors ranges from self-developed plan (board) games and collective intensive workshops to in-depth analyses of the everyday life of residents, simultaneous heterogeneous design tasks and scales, the performative dancing of walls, to drawing and communicating with spreadsheet programs.
