MacCormack Jamieson Prichard (MJP) has won the go-ahead for its plans to overhaul Broadcasting House - the BBC's West End headquarters.
Westminster council last week gave the green light for the new flagship building, which has been the focus of protracted negotiations between the corporation and the borough's planners.
In February, BBC senior executive Alan Yentob reacted angrily after planners called for major modifications to the scheme, including the replacement of the glass facade with Portland Stone and a reduction in the overall height and bulk. The BBC denied at the time that it was threatening to move its entire operation out of Westminster if its plans were thwarted.
The scheme has now changed considerably - MJP has remodelled the facades and relocated and redesigned the two northern staircores as well as the staircores over Hallam St and Portland Place.
The south-eastern promontory has also been extensively remodelled to improve the relationship between the Portland stone and glass elements of the facade.
The BBC claims 'the overall result has been to resolve issues of apparent height and bulk while preserving the quality and integrity of the underlying architecture'.
CABE and English Heritage have teamed up to give their united, 'wholehearted support' to the design. However, local residents have accused the BBC of falsifying data submitted to the planning committee. Yann Lothori, representing the residents of 89 Great Portland Street, said the residents will appeal to mayor Ken Livingstone to order refusal.

'We need to ensure that architects learn from the terrible mistakes of the 1960s when buildings were built with terrible effects on the communities they were designed to serve.'
Architects are in a 'fantastic position' to help, she added, 'through design quality, engagement with the community, education and improving access'.
'We want to make people believe that public buildings belong to them, ensuring they are not alienated and feel comfortable visiting them, ' she said.
