3XN architects was established in 1986, and is today one of the leading architecture studios in Scandinavia, working with a wide range of projects across the globe. In 2007 3XN established GXN; an in-house Innovation Unit working with digital tools, new materials and green technologies in order to ensure the studio’s leading position within building sector innovation. The ‘G’ stands for Green, highlighting GXN’s dedication to ecological design research through digital processes and innovative material solutions. The core goal is to develop a building culture that positively affects the world in which we, live both architecturally and Lasse Lind, architect and head of GXN consulting, will tell about the studios work in the Crossfield between research and building practice, and how the office is striving to implement a circular economy in the build environment.
