HSB Turning Torso is a skyscraper in Malmö, Sweden, located on the Swedish side of the Öresund strait. The tower reaches a height of 190 metres (623 feet) with 54 stories. Upon completion, it was the tallest building in Scandinavia, the tallest residential building in the EU and the second tallest residential building in Europe, after the 264-metre (870 ft)-high Triumph-Palace in Moscow. A similar, taller skyscraper featuring a 90° twist is the Infinity Tower, currently under construction in Dubai, United Arab Emirates.
It uses nine segments of five-story pentagons that twist as it rises; the topmost segment is twisted ninety degrees clockwise with respect to the ground floor. Each floor consists of an irregular pentagonal shape rotating around the vertical core, which is supported by an exterior steel framework. The two bottom segments are intended as office space. Segments three to nine house 147 luxury apartments.
