Evolution Tower

The Evolution Tower is a skyscraper located on plots 2 and 3 of the Moscow International Business Center in Moscow, Russia. The 55-story office building has a height of 246 meters (807 ft) and a total area of 169,000

square meters (1,820,000 sq ft). Noted in Moscow for its futuristic DNA-like shape, the building was designed by British architect Tony Kettle in collaboration with University of Edinburgh's Professor of Art Karen Forbes. Construction of the tower began in 2011 and completed in late 2014. 

The Evolution Tower is designed by British architect Tony Kettle in collaboration with University of Edinburgh's Professor of Art Karen Forbes, RMJM architecture firm, and Philipp Nikandrov, chief architect of engineering firm Gorproekt. Despite the design being compared to the double helix-shape of DNA, Kettle stated his main inspiration was Auguste Rodin's sculpture, the Kiss.

This is possibly why the building reflects two ribbons wrapping around each other: symbolizing the inter-linking of individuals, generations, and families. The plot covers an area of 2.55 hectares, of which most are landscaped into a terrace while the rest is used for the tower. The tower and the terrace are built on a three-level stylobate designated the Evolution Gallery with an area of 28,000 square metres (300,000 sq ft). There are exits from the tower that lead directly to the metro station Vystavochnaya and Bagration Bridge. The roof of the stylobate is made exploitable for fountains, terraces, and cafes. The difference in heights between the top of the stylobate and the embankment is compensated by stairs protected by canopies. Under the stylobate is multi-level parking for 1,292 cars.

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 case, 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.

For the project, a self-lifting form-work system was designed, combining the functions of wind protection and working platform. Thanks to this, it was possible to achieve the floor's strength in 6 days. The top of the tower is crowned with two asymmetric "arches" spanning 41 m, visually uniting the two opposite facades. They were produced in Piedmont, Italy, and delivered to Russia.

The Evolution Tower uses the single-glazing facade with cold-mirror SunGuard High Performance glass from Guardian Industries for its windows. A continuous band of curved glazing with an area of 60,000 square metres (650,000 sq ft) with a constant inclination in the corners of the tower (approximately 14 degrees to the vertical) creates an optical illusion, reflecting Moscow panoramas turned upside down at an angle of 90 degrees to the horizon.

The building uses Thyssen Krupp's elevator system: two elevator cabins independently circulate in one elevator shaft, which reduced the number of elevator shafts from twelve to ten.

Space of the Evolution Tower would be utilized primarily for office purposes but there would also be shopping galleries, boutiques, restaurants, cafes, a supermarket and banquet halls.
