Claesson Koivisto Rune is a Swedish design/architecture office based in Stockholm. It was founded in 1995 by former University College of Arts classmates Mårten Claesson, Eero Koivisto and Ola Rune.
Their multidisciplinary practice has created a diverse range of products for a broad spectrum of manufacturers including Arflex, Cappellini, Fontana Arte and Wästberg, always with the idea "to develop, to improve and never to repeat".
Architectural projects include the Sfera Building in Kyoto, prefabs Plus House and Tind House and interiors such as the Operakällaren restaurant in Stockholm’s Royal Opera House.
