Firm Description

Kim Herforth Nielsen founded 3XN Architects in 1986 in Aarhus, Denmark. Now based in Copenhagen with an additional office in Stockholm, four senior partners direct the firm: Founder and Creative Director Kim Herforth Nielsen, CEO Jeanette Hansen, Head of Design Jan Ammundsen and Director of GXN Kasper Guldager Jensen. Six additional partners complete the leadership group.

In 2007 3XN established GXN, an internal innovation unit, whose mission is to collect and apply the latest knowledge on materials and new technologies to the studio’s architecture.

The abiding philosophy that architecture shapes behaviour guides all of the firm’s work, from the revolutionary design of Danish upper secondary school Ørestad College to award-winning corporate headquarters for clients including Swedbank and Deloitte, residential buildings and cultural destinations. 3XN, through daring concepts and design, creates architecture that contributes positively to living, learning and working environments.

3XN believes that a new building should always add new and positive qualities to the site. This happens through careful analysis of the area, the surrounding buildings and the client brief. They see the project’s complexity and challenges as positive creative forces, which inspire them to create something unique. The firm creates places that support interaction and communication, and where synergy can grow.

Buildings, like people, are more than just the sum of their many parts. We think that it is possible to achieve a synthesis of design, function and context. That is why a holistic approach is the guiding principle, and why they are forever exploring the possibilities of building better, smarter, more beautifully.
