GXN was established in 2007 as an internal division of Danish architectural practice 3XN, and has since day one been working with applied architectural research in green materials and building technologies. The ‘G’ stands for Green, highlighting GXN’s dedication to ecological design research through digital processes and innovative material solutions. GXN competencies span over architecture and design projects, research and innovation and external consultancy.

GXN has developed partnerships with leading experts across various industries for investigation in material research, data analysis, biology, and digitalization. Using applications of building innovation technologies from several disciplines allows GXN to create custom solutions for unique architectural challenges.
