Founded in 2003 by Dr. Phillip F. Yuan, Archi-Union Architects is a Shanghai-based architectural design firm. Archi-Union is known for combining global trends in architecture and the local traditional approach. They have coined the term 'Digital Tectonics' to describe their low-tech digital fabrication methods which merge the concepts of tectonic construction and ecology that are catalysed through a parametric design process, in essence combining digital technology and craftmanship.
