Advertisement Evolution Tower is a twisting 255 meter tall skyscraper located in ‘Moscow City’, Moscow, an initiative by the Russian government to create a new business district on an old industrial site. The twisting tower provides approximately 85,000 m² of retail and leisure facilities and 85,000 m² of offices and public functions. It is the twelfth tallest building in Russia and the 20 th tallest in Europe. The dramatic form of the tower was designed by architects RMJM in collaboration with Scottish artist Karen Forbes. The double helix DNA inspired form has become an iconic landmark in the Moscow skyline, as the city has never been known for its skyscrapers or architectural identity. The form is also reminiscent of two ribbons wrapping around each other. Each of the 51 floors of the tower is rotated 3 degrees relative to the previous one, so the building is “swirled” by more than 150 degrees. In this way, the central core and eight columns with 15-meter spans between the axes remain strictly vertical all the way up. The spiral geometry is repeated only by four corners of the building. The top of the tower is crowned with two asymmetric “arches” spanning 41 m, visually uniting the two opposite facades.
