Laurenz Andritz recognised his penchant for geometries outside of the orthogonal grid during his time at a vocational secondary school for mechanical engineering. As one of the first students to have access to computers with 3D CAD software, he supervised several geometrically challenging projects while studying architecture at the Vienna University of Technology. In this context, he was involved in the Austrian contribution to the 51st Venice Biennale for Hans Schabus, in which a pavilion was covered by a mountain-shaped wooden structure. Andritz's diploma thesis in 2007 was an interdisciplinary collaboration with the Institute of Railway Engineering and focused on the topic of underground railway stations.

Shortly afterwards, he moved to Leipzig to work as an architect at Schulz & Schulz Architekten . In 2010, Andritz founded the office 3ACHS Konstruktion und Design, which primarily serves 3D-relevant topics in the engineering sector and for artists. Using Rhinoceros and Grasshopper, workflows were developed to create production data from parametric models for complicated 3D timber constructions, foil cushion systems and element facades. He has been a research assistant at HTWK Leipzig since June 2021 and has been involved in projects such as OptiPaRef involved. His current focus is on creating a user-friendly interface between Rhino and KUKA robots.
