Villa Stenersen in Oslo, Norway

This striking villa, completed by renowned architect Arne Korsmo in 1939, is one of the most important works in the functionalist style in Norway. The house was built for Rolf Stenersen, a businessman, olympic athlete, author, codebreaker and longtime friend of Edvard Munch - Munch actually painted works specifically for this villa (today copies hang in their place). The outbreak of WW2 forced Stenersen to flee to Sweden, and he was not able to return to his house until the end of the war. In 1974 he donated his house to the state, intending it to become an official residence for the government. In fact, one prime minister, Oddvar Nordli, did occupy the house for a while. Later the house was the residence of the Stoltenbergs, during which time Nelson Mandela was a guest. The house was eventually restored, and opened as a museum. Today free tours are arranged during the summer (an audioguide is available). The house is a key example of the functionalist style, and is recognized as a member of the Iconic Houses Network. Le Corbusier was a key source of inspiration for Korsmo. The house has many interesting features. For instance, the stairwell has a skylight made from 625 purple conical shaped pieces of glass, creating a dazzling effect. The garage is arc shaped such that it is not necessary to reverse when parking - Stenersen was supposedly not a fan of driving. Original statues dot the garden, and some original furniture designed by Korsmo remains in the house.
