Piling and excavation works are close to completion on the landmark 36-storey project, which will feature the country’s tallest living wall.

The 650,000 sq ft green tower project is now expected to complete in 2028.

Designed by Eric Parry Architects, Fifty Fenchurch Street is set to be one of the UK’s most sustainable and biodiverse high-rise office buildings, targeting BREEAM Outstanding and net zero in operation.

It will be the first building of this scale to incorporate such extensive vertical landscaping in the City of London, comprising 10th floor internal and external gardens including more than 40 planted balconies and terraces.

Street-level gardens also feature the Medieval Church Tower of All Hallows Staining as a historic centrepiece above a substantial new subterranean Livery Hall for The Clothworkers’ Company.

Rob Samuel, UK Head of Development at AXA IM Alts, said: “Our success at 22 Bishopsgate has confirmed the importance of tailoring buildings to align precisely with the evolving needs of occupiers to create high-quality, innovative workspaces that make employees want to come to the office.

“At Fifty Fenchurch Street our aim is to deliver exactly that, creating a landmark structure that will be both one of London’s most biodiverse office towers and combine best-in-class workspace with green, accessible public areas that uniquely incorporate heritage buildings that will enrich the City of London’s landscape.”
