Tor Alva

Tor Alva is the world’s tallest 3D-printed building in the alpine village of Mulegns, Switzerland. Led by the Origen Cultural Foundation in collaboration with ETH Zurich, the tower reimagines Mulegns’ cultural legacy through architecture. Designed as an immersive performance space, the White Tower features a cupola theater enveloped by a forest of filigree branching columns – a breathtaking venue above the village rooftops.

The project serves a dual purpose: to create a one-of-a-kind performance space that merges architecture, culture, and science, while also revitalizing a village confronting structural challenges. Additionally, it showcases the interdisciplinary research from ETH Zurich, advancing digital building practices that foster innovative, rich, and sustainable environments.

With its pioneering digital achievements, both in design and in fabrication, the White Tower demonstrates the possibilities that robotic construction holds for architecture and construction, especially in advancing reinforced 3D concrete printed loadbearing elements.
