Possibly the first, modern, twisted skyscraper constructed was the Turning Torso in Malmo, Sweden.
The construction of this building was featured on Discovery Channel’s “Extreme Engineering” TV program.
After the successful completion of the Turning Torso, designers started proposing similar audacious structures elsewhere.
Construction of the building began in February 2006 and by 2012, the intended height was reached.
Each floor is rotated by 1.2 to achieve the full 90 spiral, creating the shape of a helix.
Not a dramatic 90-degree twist, but a head turner anyways.
It is the headquarters for Dnevni avaz, a Bosnia and Herzegovina newspaper company.
One is 179 meters tall while the other stands at 161 meter.
The 242-meter reinforced concrete tower consist of 52 floors and makes a 360 degree turn as it rises up.
The following images are computer renders depicting how the towers will look once completed.
Actual pictures of the tower, which is still being built, is not available.
Construction of the tower began in 2007, and was planned to be completed in 2013.
As of April 2013 they are working on the 42th floor of the building.
The tower is designed by architect Tony Kettle.
The above is a computer render.
Constructed of stainless steel, the tower is memorable for the noticeable twist in its outer facade.
Spiral Towers appears to change shape slightly when viewed from different angles, giving an elegant yet dynamic impression.
