Richard Rogers Partnership's Leadenhall Building has won planning permission from the Corporation of London.
The corporation's planning and transportation committee decided on Tuesday that the 58-storey skyscraper should get the green light.
The 224.5m-high tower, nicknamed the 'doorstop', will include 53,600m together with bars, restaurants and a theatre.
The tower - drawn up for British Land - was expected to win the permission after city planning officer Peter Rees announced the planning department's decision to support it (AJ 21.10.04).
The building's glass facade encloses a structural steel frame, with colour and light adding depth to the north-facing facade that will give, according to Rogers, a 'strong sense of identity and character'.
However, opposition from some heritage groups, including SAVE Britain's Heritage and the City Heritage Society, has been strong and it is as yet unclear whether deputy prime minister John Prescott will decide to call it in.
