These plans, for the site at 63 St Mary Axe, include a car park, multi-function ground level auditorium and other public amenities.

This will be the fifth office development AXA IM Alts has advanced in the Square Mile since 2012.

Fletcher Priest Architects have designed the building to ensure access to gardens and fresh open air from every office floor.

Over 100 trees will be included in the design to provide natural shading and for aesthetic purposes.

AXA IM Alts will develop the building to be fossil fuel free, all-electric and target BREEAM Outstanding and NABERS five star certifications.

Rob Samuel, UK head of development at AXA IM Alts, commented: “Designed as a low carbon building for future generations, 63 St Mary Axe will help to address the significant shortage of high quality, modern, sustainable and amenity-rich workspaces, not just in the City but across central London as a whole.
 
“In formulating our plans for the site, it was important for us to work closely with local communities, business occupiers, start-ups and other public and private sector bodies, to ensure that 63 St. Mary Axe bridges the gap between local people, City workers and tourists.

“It is intended to be an inclusive building which delivers the type of innovative and forward thinking workspace that helps the City of London continue to attract global occupiers.”
