Bo01 (also known as the "City of Tomorrow") was a housing expo in the southern Swedish city of Malmö. It was created as part of the European Housing Expo in 2001 and is notable for its sustainable character. The most notable building built for Bo01 was the Turning Torso skyscraper, which became the tallest building in Scandinavia. It was however not completed in time, and was not ready until 2005.
