The tallest building in the City of London, 22 Bishopsgate has reached the stage of “practical completion”, and is starting to be fitted out for tenants.
The skyscraper, 22 Bishopsgate sits on the site of the cancelled Pinnacle — the “helter-skelter” — which had started being built but stopped in 2012 due to the recession, with only the concrete core of the first seven storeys built. The replacement design was approved in 2017 is for a 278-metre high, 62 storey building.
The construction form, Multiplex says that twice the amount of steel used on the Eiffel Tower was required to deliver the building’s main superstructure, comprising a steel-framed tower with a central supporting concrete core. The basement is three levels deep with a network of supporting columns and transfer structures taking loads down to piled foundations. 22 Bishopsgate is also the tallest building in the world to use the advanced closed cavity façade (CCF) curtain wall system, which circulates air within the cavity while preserving clear glazing.
Inside, the building will have London’s fastest double-decker lifts.
When it opens there will be a free public viewing space on the 58th floor, along with a restaurant and bar on the two remaining floors above. The very top of the building will also be able to have a scrolling lighting effect.
At the ground floor, the pavements are starting to be handed back to pedestrians, and multicoloured glazed panels have been installed which helps to add a bit of interest to the otherwise fairly grey glass shell of the building.
A series of large canopies look like they might be there to protect from the rain, but are too high up to offer much in the way of shelter — because they’re actually to deflect downdrafts and reduce wind-tunnel effects caused by tall buildings. If they also look slightly like they belong on the back of an F1 car, that might be because they were designed using wind modeling supplied by Formula 1 engineers.
Of the 62 floors, just 15 remain to be let by the owners. The first tenants are now expected to move in early in 2021 following fit-out of their office spaces.
In total, around 12,000 people could work in the building when full.
*It’s the tallest in the City of London, the Shard is taller, for Greater London.
