Scotland-based architecture company Kettle Collective has announced plans for what it says will be the second tallest skyscraper in the world.

Currently known only as the ‘Kakhta Center II’, the tower will be built in St Petersburg, Russia, and will reach a height of 703 metres tall.

According to Kettle Collective, that means the building will be twice as tall as the 380m high Shard in London and 71m taller than China’s Shanghai Tower.

While no indication of a start or completion date was given for the project, the architecture firm said the tower would have roughly 220,000m2 of accommodation space and a 590m2 top floor viewing gallery.

Kettle Collective, which recently won the 2021 Queen’s Award for Enterprise for Sustainable Development, said the viewing gallery would be the highest of any building in the world.

The tower’s structure will comprise eight segments, each containing 16 floors with triple height atrium space levels and shared public facilities.

A specialist in high performance and energy efficient structures, Kettle Collective’s design for the tower’s core incorporates multi-car lifts that will be powered by the energy generated by their own lifting movement.

Tony Kettle, design Lead at Kettle Collective, said, “The new Lakhta Center will be a template of sustainable design for global high-rise projects. It will have the best-in-class low energy design and a mix of uses that will create a vertical atrium space with a vibrant centre as the heart for this new business district.

“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.”

Described as a “complimentary development”, the Lakhta Center II tower will be built next to the 462m tall Lakhta Center, which is owned by Russian energy corporation Gazprom.
