3XN was founded in Aarhus in 1986. The studio quickly became known for creating buildings of substance with compelling aesthetics supported by a strong theoretical foundation. The projects also featured a high level of detail and employed workmanship of the best quality. Now based in Copenhagen with an additional office in Stockholm, the firm is led by three Senior Partners: Founder and Creative Director Kim Herforth Nielsen, Head of Competitions Jan Ammundsen and Director of GXN Kasper Guldager Jensen. In 2007 3XN established GXN, its innovation unit, whose mission is to collect and apply the latest knowledge on materials and new technologies to the studio’s architecture.

The revolutionary design of Danish upper secondary school Ørestad College, together with a number of original corporate headquarters designs, especially Swedbank, shows that 3XN, through daring concepts and design creates architecture that contributes positively to learning and working environments.

These innovations are also reflected in master plans and multi-unit residential projects like the Lighthouse in Aarhus and Denmark’s new national aquarium, The Blue Planet, in Copenhagen.

3XN believes that a new building should always add new and positive qualities to the site and the brief. This happens through careful ana­lysis of the site, the surrounding buildings and the client brief. We see the project’s complexity and challenges as positive creative forces, inspiring us to create something unique for the site and purpose.

Architecture shapes behaviour. That is why we try to create places where people can interact and communicate and where synergy can grow. We believe that buildings, like people, are more than just the sum of their many parts. We believe that it is possible to achieve a synthesis of design, function and context. That is why a holistic approach is our guiding principle, and why we are forever exploring the possibilities of building better, cleverer, more beautifully.

We build on the Scandinavian tradition of clear functionality and simple beauty. Each new project rests on the shoulders of our previous work, even though we always challenge conventions. We see each new project as an opportunity for research that enhances our experience and sharpens our approach.

3XN combines a broad knowledge of materials, technology and user needs with organizational strengths in financial management, project management and execution. It gives us the freedom to push boundaries and challenge traditional thinking. And it means that we can work in safe knowledge that we can make playful and innovative architecture rise from the drawing board and come alive.

The firm’s work has been recognized with many international awards and its projects are regularly published in design and business media around the world. Kim Herforth Nielsen and his partners are also frequently invited to speak at conferences and universities, participate in design criticism at schools of architecture and serve on industry and government committees dedicated to design and education.

3XN translates visions into reality and is continually committed to making today’s work tomorrow’s architectural heritage.
