The developer on the City of London scheme dubbed Gotham City confirmed that Mace would finally start work on the job in March 2020.
Designed by Make Architects, the firm was named preferred bidder in 2015 but the scheme at 40 Leadenhall Street (pictured) was stalled a year later after its then developer TH Real Estate hit the pause button following the result of the EU referendum.
Keltbray began clearing the site in 2018 before M&G Real Estate bought the development last November for £895m. The scheme has permission for two office towers of 14 and 34 storeys.
South London Timber have been supplying construction timber to this project.
