Semiramis Installation: AI-Driven Timber Pavilion in Tech Cluster Zug

The Semiramis Installation is a pioneering architectural structure designed by Gramazio Kohler Research in collaboration with ETH Zürich, Müller Illien Landschaftsarchitekten, Timbatec Timber Construction Engineers Switzerland, and Urban Assets Zug AG. Completed in 2022, this innovative timber installation stands at the entrance of Tech Cluster Zug, Switzerland, symbolizing the synergy between artificial intelligence, digital fabrication, and ecological urbanism.

AI-Driven Computational Design & Digital Fabrication

Developed using a machine learning-driven design approach, Semiramis was shaped by an interactive process that optimized its form, environmental performance, and structural integrity. Researchers from ETH Zurich and the Swiss Data Science Center generated various design iterations, considering key factors such as sunlight exposure, rain protection, and plantable surface area.

The installation consists of five organically shaped wooden pods, elevated 22.5 meters above the ground and supported by eight slender steel columns. Its unique cross-laminated timber (CLT) panels were fabricated using robotic assembly methods developed in collaboration with TS3 and the Chair for Timber Structures at ETH Zurich. The innovative butt-joint bonding technique allowed for the creation of large, folded timber structures without the need for traditional fasteners.

Robotic Assembly & Automation

A groundbreaking aspect of Semiramis’ construction was the simultaneous operation of four industrial robots at ETH Zurich's Robotic Fabrication Lab, marking a milestone in robot-assisted timber construction. The research team collaborated with Intrinsic to integrate their robotic planning technology with COMPAS FAB, an open-source robotic fabrication framework.

Urban Ecology & Biodiversity Integration

Designed as an elevated urban habitat, Semiramis provides an untouched sanctuary for local flora and fauna. Developed with Müller Illien Landschaftsarchitekten, the landscaping concept introduces a self-sustaining green micro-ecosystem that will evolve over time. Pedestrian access to the pods is restricted, allowing nature to flourish undisturbed.

With its integrated irrigation system, the structure regulates green densification while providing shaded areas and improved microclimatic conditions for visitors and workers in the Tech Cluster Zug. Over time, as new buildings emerge around Semiramis, the installation will become an integral part of an expanding green urban network.

Rethinking the Future of Digital Timber Architecture

Beyond being a striking architectural landmark, Semiramis challenges conventional urban design paradigms by blending advanced robotics, machine learning, and ecological awareness. As a living experiment in AI-driven architecture, it offers insights into the future of digital timber construction, modular design, and urban biodiversity.
