The main designers of Harpa Concert Hall and Conference Centre are the Danish architectural firm Henning Larsen Architects and the Icelandic architectural firm Batteríið Architects.
Danish-Icelandic artist Olafur Eliasson designed the south facade, and developed the principle for the remaining north/east/west facades and roof in collaboration with Henning Larsen Architects and Batteríið Architects. Elíasson deploys light, colour and natural phenomena to test how physical movement, sensual engagement, and the interaction of body and brain influence our perception of our surroundings.
Henning Larsen Architects has gained a reputation for superb design, including the new Opera House in Copenhagen. Batteríið Architects have won numerous awards for their design, including the extension for the Icelandic Parliament. The firm works internationally in close cooperation with contractors and renowned architects and engineers in the Nordic countries, North America and Australia.
The US consulting firm Artec Consultants Inc. is responsible for the acoustics, sound isolation and design of the theater and sound equipment in all the venues.
