High Performance, Economical & Sustainable Biocomposite Building Materials


3XN was founded as Nielsen, Nielsen and Nielsen in Aarhus in 1986 by the architects Kim Herforth Nielsen, Lars Frank Nielsen (partner until 2002) and Hans Peter Svendler Nielsen (partner until 1992). The three Nielsen architects, often referred to as the Nielsens – and today simply as 3XN – quickly became known for two things: their preference for ground-breaking architecture, in defiance of the antihumanistic modernism, and projects demanding a high level of detail and employing workmanship of the highest quality.

In 2007 3XN established GXN; a Research & Development department that scans the market and the latest research for pioneering ideas, focusing on green and digital architecture, new materials, technology, and working methods.
