Europe’s New Conference on Architectural Politics

Thank you to everyone who joined us in Copenhagen on September 18–19, 2025, for Assemble! — a two-day glimpse into the building sector of the future, hosted by the Copenhagen Architecture Biennial 2025 in collaboration with the Green Youth Movement (Den Grønne Ungdomsbevægelse).

About Assemble!

Our shared goal is clear: create a building sector that operates within planetary boundaries and ensures a thriving future for both people and planet.

Systemic change can’t happen in silos.

That’s why Assemble! brings together architects, poets, engineers, activists, economists, advertising advisors, developers, legal experts, and practitioners to rethink the regulations, ownership models, and design processes that quietly define our cities. Assemble! is a structural experiment, a policy rehearsal, and a launchpad for bold ideas to become real-world action. It takes you from drafting up inspiring new legislation, to testing its implications, and to creating sustainable, engaging narratives that capture the public imagination—while inspiring change across the sector.

At Assemble!, you will:

• Receive concrete tools for your everyday practice
• Meet and network with peers from across the building sector
• Develop new narratives and strategies to influence decision makers
• Leave with actionable ideas ready to spark long-term impact

We  extend our gratitude to our Advisory Board: Nicolai Bo Andersen, Christine Bjerke, Hassan Chaachouh, Kika Brockstedt, Kenneth Balfelt, Mette Skjold, Line Thorup Schulz, Camilla van Deurs, Vibeke Grupe Larsen, Pernille Schyum Poulsen.

DAY ONE: Breaking Barriers Through Law / 18 September

Day One delivers radical ideas, rigorous debate, and new inspiration. After the opening speech by Katherine Richardson,  you’ll experience innovative law proposals by: Kate Orff, Indy Johhar & Anders Lendager. Their proposals are followed by panel discussions with key players across the building value chain — from developers and engineers to contractors, economists, and legal experts and supported by best-practice case presentations that will showcase how these future-oriented ideas are already taking shape in built and planned projects.

All talks are moderated by
Kristoffer Lindhardt Weiss is the director of Danish Architectural Press. He has a background in philosophy from the University of Copenhagen and the Paris-Sorbonne University, Paris IV.
