An article on the Guardian's website has claimed that due to a 'change in strategy' at the BBC the high-profile project has been delayed yet again.
The scheme has been no stranger to controversy. Last year it was announced that the project's completion date had been pushed back from 2008 to 2010.
And in October 2005 the project's original designer, Richard MacCormac's firm Jamieson MacCormac Prichard, was dropped from the scheme in favour of Sheppard Robson.
It was thought that MacCormac might make a return as a consultant on the development back in 2006, but this failed to happen.
The first phase of the project was completed last year, and saw a full refurbishment of the Grade II-listed Broadcasting House in central London.
It is unclear what the reasons behind the delay really are, and at the time of writing neither Sheppard Robson nor contractors Bovis Lend Lease were able to give a response.
