The Danish architectural firm 3XN prides itself on a Nordic sensibility that combines natural materials with an abstract, dynamic, modernist approach. Established in 1986 in Aarhus, the firm, which gained prominence with its design for the Royal Danish Embassy in Berlin (1999), moved to Copenhagen in 2004. As it increasingly won large-scale commissions, such as the Saxo Bank in Copenhagen (2009), its own loftlike warehouse space facing the harbor in Christianshavn felt more and more cramped. With 100 people, 3XN'which refers to the surnames of its three founders, Kim Nielsen, Hans Nielsen, and Lars Nielsen (none related)'decided to relocate. Last December, the architects moved into five of 32 wood buildings once used by the Royal Danish Navy for the repair and storage of military gunboats in Holmen, a group of small islands in the city. From 1690 to 1993, Holmen had served as the navy's base, but after its departure, the area, not far from the Copenhagen Opera House, began to turn into a cultural enclave. The Royal Danish Academy of Fine Arts schools and educational facilities for theater and music are now located there, and the black-stained wood gunboat sheds are being renovated and leased to assorted businesses in fields such as media, advertising, and architecture.
