Designs have been unveiled for a 703-meter-high megatall skyscraper in St. Petersburg, Russia. Called Lakhta Centre II, the 150-story building plans to have an occupied floor at 590 meters.

The tallest building in the world is the 828-meter-high Burj Khalifa in Dubai, which was designed by Skidmore Owings & Merrill (SOM). 

Designed by Kettle Collective, Lakhta Centre II would sit next to the Lakhta Centre, the headquarters of Russian energy firm Gazprom that completed in October 2019.

Kettle Collective founder Tony Kettle was previously design director for Edinburgh architecture practice RMJM and created the competition-winning design for the 462-meter-high Lakhta Centre in St Petersburg. The project was later handed over to Russian architects Gorproject to complete.

Renders from Kettle Collective show a design for the Lakhta Centre II skyscraper with a helical glazed form cradled within a metal exoskeleton. The tower will house multi-car lifts, powered by regenerating energy from the movement of the lift, according to Kettle Collective. 

“The design is both aesthetic and functional as it will reduce considerable wind forces that will impact the structure, in turn reducing the size of structural elements required within the building,” said Tony Kettle.
