Winy Maas discusses the making of the kinetic Sombra Pavilion and the 3D printed Biotopia installation at the Venice Architecture Biennale 2025.The Sombra Pavilion relies on air pressure generated by heat differences within its structure to create shade without using electricity.Biotopia envisions a future where buildings grow like living organisms and is part of The Why Factory collaboration at the Biennale.The installation explores a self-sustaining world based on biomimicry, where cities are like forests and architecture grows like trees.Winy Maas discusses a biotopic world that combines energy, oxygen, shelter, and other essential properties in a recyclable, biological manner.His vision involves creating a city where materials facilitate diverse needs precisely when required, leading to transformative urbanism.The installation at the Arsenale includes a 3D printed sculpture and a film documenting Maas' research on biotopia and biomaterials.Maas also envisions using innovative 3D printing methods involving a material bank, mixed printer, and an 'un-printer' for varied material use.He explores biomaterials like mycelium and lignin, aiming to advance material fluidity and adaptability in architectural design.The discussion also touches on the integration of computational design, algorithms, and collaborative research at MVRDV.
