Famed for the deployment of natural light in his designs, Larsen is known for the main municipal library in Malmö Sweden; Saudi Arabia’s Ministry of Foreign Affairs building in Riyadh; the Harpa concert hall/conference center in Reykjavik; and the 2005 harborfront Copenhagen Opera House – over which his battles with the builder and funder of the project, shipping magnate Mærsk McKinney Møller, became famous.
