The structure is made up of nine "cubes" of five stories each, stacked one above the other with one floor recessed between every two adjacent cubes.
Inspired by a sculpture made by the building's architect, the tower twists 90º from top to bottom (hence the "Turning" in the name).
Glazed panorama rooms with room for 20 people each are situated at the 49th and 43rd floors, between the 8th and 9th cubes and the 7th and 8th cubes respectively.
The building holds the highest apartments in Europe.
The two lower cubes contain offices and conference rooms, and the top two floors hold a conference center.
The building was constructed to restore the Malmö skyline after the 130 meter high Kockumskran crane was demolished.
Because of the curving facade, it was impossible to install hoists during construction. Instead the main core elevators were used to lift construction materials, and were built in stages as the structure rose.
Along with other Calatrava designs, Turning Torso was featured as a work of art in an exhibition at the Metropolitan Museum of Art in New York City from October 2005 to January 2006.
Each apartment incorporates individual consumption monitors, allowing the residents to control their own energy costs.
Turning Torso was featured on an episode of the Discovery Channel's Extreme Engineering filmed in February 2004. It first aired in the US in July '04 and in Europe in the fall.
