The new glass and steel building will neighbour the “Walkie Talkie”, Scalpel and Leadenhall “Cheese Grater” skyscrapers.
The proposed development will include new food and drink spots, and a pedestrian route connecting Cullum Street to Fen Court.
An external garden terrace located on the 17th floor of the building will be accessible to the public and is designed to provide green space and panoramic views.
A public rooftop gallery will also be based on the 20th floor.
Ben Littman, head of development at Aviva Investors, one of the developers behind the tower, said it was a “bold and thoughtful scheme that will bring a long-vacant site back into positive use.
“It reflects the best of what the City can offer; ambition, culture, sustainability and inclusivity.”
