Sweden's tallest residential building is the HSB Turning Torso, a sculptural sustainable skyscraper that gently spirals as it ascends above the skyline of Malmo. Designed by renowned architect, sculptor and structural engineer Santiago Calatrava, the gigantic tower stands 54 floors high and features a form inspired by the Spanish architect's studies on nature and human bodies. The fantastic tower is completely powered by renewable energy, and it twists a full 90 degrees from top to bottom.
