What Gramazio Kohler Research does
Gramazio Kohler Research is the Chair of Architecture and Digital Fabrication at ETH Zurich, established around 2005, and led by Prof. Fabio Gramazio and Prof. Matthias Kohler. The group investigates how introducing digital manufacturing techniques changes architectural production, with research spanning robotic fabrication in timber, brick, concrete, and steel, computational design of complex geometries, and the integration of extended reality (XR) and AI into architectural workflows. The group's strategic output includes the open-source COMPAS framework (a Python-based geometry and algorithmic design toolkit for the AEC industry), COMPAS XR for VR/AR integration, and COMPAS cadwork for cadwork CAD interoperability. Demonstrated projects include 93 computer-designed balustrades for the historic Hotel Schatzalp in Davos, the "A Robot's Dream" humanoid-robot installation at La Biennale di Venezia 2025, and the MIRRORWORLDS XR/AI installation shown at MUNCH Oslo and the Space for Contemporary Architecture in Vienna.
Gramazio Kohler Research operates as an academic research group within ETH Zurich rather than a commercial company. Its outputs are distributed through research publications, international architecture exhibitions (La Biennale di Venezia, MUNCH Oslo, Utzon Center Aalborg), academic conferences (RobArch, CAADRIA, Future of Construction, Smart Geometry), GitHub-hosted open-source software, and educational programs including the MAS ETH Architecture and Digital Fabrication master's program and undergraduate teaching. Revenue in a commercial sense is not generated; funding flows from ETH Zurich institutional resources, Swiss National Science Foundation grants, EU Horizon Europe programs (notably XTREME), Pro Helvetia, and industry partners including MESH AG, Holcim AG, Häring Timber Engineering, and Unitree. The research group collaborates closely with other ETH chairs (BLOCK Research Group, Chair of Landscape Architecture, Computational Robotics Lab, Robotic Systems Lab), external academics (XAIA Lab at Princeton, Politecnico di Torino), and a network of architecture and construction industry partners.
The group's competitive position rests on its 18+ years of accumulated research output, two globally recognized founders with strong academic reputations, the COMPAS open-source ecosystem gaining adoption across the AEC industry, and privileged access to ETH Zurich's institutional and funding infrastructure. Growth signals include product launches (COMPAS XR, COMPAS cadwork), geographic expansion across Europe (Pamplona, Kharkiv, Aalborg, Oslo), emerging commercial spinouts (MESH AG), and ongoing exhibitions at major venues. As an academic entity embedded in a public university, the group's growth trajectory is better measured in research scope, partnership breadth, and ecosystem influence than in commercial revenue.

Gramazio Kohler Research product offering
Product offeringCore offering
Gramazio Kohler Research is the Chair of Architecture and Digital Fabrication at ETH Zurich, conducting research and teaching on how digital fabrication, robotics, and computational design change architectural production. The group develops and releases the COMPAS open-source framework (with COMPAS XR and COMPAS cadwork extensions) for the AEC industry, builds custom robotic fabrication systems for timber, brick, concrete, and steel, and runs academic programs and experimental installations exploring human-machine collaboration in architecture.
Product overview
Gramazio Kohler Research is the Chair of Architecture and Digital Fabrication at ETH Zurich, operating as a research institute rather than a commercial product company. Their portfolio consists of open-source software frameworks (COMPAS, COMPAS XR, COMPAS cadwork) for computational design and digital fabrication in the AEC industry, combined with educational programs (MAS, courses), research installations (A Robot's Dream, MIRRORWORLDS), and access to a Robotic Fabrication Laboratory. The COMPAS framework serves as the core open-source product providing Python-based geometry processing and algorithmic design tools, while COMPAS XR extends this into extended reality applications and COMPAS cadwork provides CAD integration. These are complemented by academic programs and experimental installations exploring the intersection of robotics, AI, and architecture.

Gramazio Kohler Research competitors and assessment
Company assessmentDirect peers
- Robotic Building Lab, TU Delft: TU Delft research group led by Henriette Bier, focused on robotic and additive manufacturing for architecture and construction. Directly comparable to GKR: produces exhibited robotic-construction research, collaborates with materials suppliers and the broader AEC industry, and operates as a publicly funded academic lab at a major technical university - mirroring Gramazio Kohler's role at ETH Zurich.
- ICD Stuttgart - Institute for Computational Design: University of Stuttgart research lab led by Achim Menges, focused on computational design and robotic fabrication in architecture. Closest direct peer: publicly funded academic lab pioneering novel material systems (e.g., woven timber, carbon-fibre composites, mycelium) using multi-axis robotic fabrication - structurally analogous to Gramazio Kohler Research's mission, talent base, and partner ecosystem.
- Bartlett B-Pro, UCL: UCL Bartlett's B-Pro (formerly B-pro programmes) cluster, including postgraduate research at the Bartlett School of Architecture. Comparable to GKR as a London-based postgraduate research environment integrating computational design, robotics, and applied fabrication - sharing high international visibility, software-led methodology, and exhibition-driven dissemination.
- MIT Architecture / Digital Fabrication Research: MIT's Department of Architecture houses several research strands (Skylar Tibbits' Self-Assembly Lab, Matter Design, etc.) working on computational design and robotic fabrication. Directly comparable academically: elite US technical university housing pioneering research in programmable matter, robotic fabrication, and architectural computing - similar grant structure and global exhibition profile to GKR.
- AA Design Research Lab: Postgraduate programme at the Architectural Association School in London, directed by Roberto Pasquero and others, focused on computational design and architectural research. Comparable to GKR as a graduate-level research-training environment that combines academic study, advanced computational tools, and built projects - producing influential experimental architecture.
Broad incumbents
- McNeel (Robert McNeel & Associates): Developer of Rhinoceros 3D, the CAD platform widely used by computational-design architects and the host into which COMPAS is now packaged (COMPAS Python 3.x support in Rhino 8). Comparable as both ecosystem partner and adjacent incumbent: McNeel's reach into architectural computing defines a real commercial context for GKR's open-source tooling.
- Autodesk: Dominant AEC software vendor (Revit, AutoCAD, generative design tools). Comparable to GKR not because it competes head-to-head but because it owns the platform into which COMPAS must integrate: if Autodesk embeds advanced computational/robotic-design capabilities directly, it shapes the addressable market for GKR's open-source tooling and academic outputs.
Others
- Häring Timber Engineering: Swiss timber-engineering firm collaborating with GKR as a strategic industry partner on timber-wall and sequential-wall research projects. Comparable as a long-standing industry partner and channel for technology transfer of GKR's research into commercial timber construction.
Emerging players
- Odico Formwork Robotics: Danish robotics company building custom robotic fabrication systems, including formwork and subtractive/additive manufacturing for the built environment. Comparable to GKR as a niche player turning robotic-fabrication research into commercial systems - illustrating the type of emerging competitor GKR's spinoffs overlap with.
- MESH AG: Swiss robotic-construction startup emerging from the broader ETH Zurich ecosystem, including collaboration with Gramazio Kohler Research (partner on the La Biennale di Venezia installation). Comparable as an ETH-aligned startup commercialising robotic fabrication technology (notably rebar construction) that secured a US$3.8M seed round, illustrating the venture-style spinoff pathway out of GKR-related research.
