It's possible your social media feeds have been completely flooded with dispatches from the Venice Biennale of Architecture. The international architecture exhibition has just launched, and will take over the coastal city with national pavilions, individual architects and curators exploring themes that have ranged from cities and society – or, in the case of this year: free space.

Today's guests run Neiheiser Argyros, the international multi-disciplinary architecture practice behind this year’s Greek pavilion. Their interpretation of “free space” explores communal spaces of several universities around the world, inspired by Raphael’s fresco, The School of Athens.

We invited Xristina Argyros and Ryan Neiheiser to join us in the Pod, just before they left for Venice.
