World-famed architect, sculptor and structural engineer Santiago Calatrava has created yet another unique and unusual structure, this time in Sweden. The 54-story spiral-shaped building – called the HSB Turning Torso – stands tall over the skyline in Malmo, Sweden. It is a fascinating combined homage to the human body in movement and nature and is made of concrete, steel, glass and recycled aluminum.

Created to be a sustainable skyscraper, it’s glass facade features a double-curved shape that turns a full 90 degrees, from top to bottom. The building is powered by renewable energy which is supplied locally produced.

This is residential building is made up of nine segments of five-story floors that form an irregular pentagon layout. With so many slanted angles indoors, however, I’m uncertain how comfortable living there would be. But it would definitely be a great “break the ice” conversation!
