Man of the moment Terry Farrell has been brought in to help revamp Richard Seifert's iconic Centre Point complex.
His practice has been asked to look at remodelling the public space beneath the Grade II-listed London tower by its new owner, the Targetfollow Group.
Farrell will also investigate the impact of the multi-billion Crossrail project on the 117m-tall block.
Meanwhile, the owners have chosen Rolfe Judd Architects to carry out a major internal refurbishment of the 32-storey skyscraper, which was built between 1962 and 1964.
The appointments form part of a major overhaul of the centre, which is to include the opening of a restaurant and private members' club on the top two floors.
Ian Fox, a director with the Targetfollow Group, said: 'We are pushing ahead with exciting plans to completely revitalise this outstanding landmark and transform it into an unrivalled business destination.'
He added: 'It enjoys one of the most central locations in the capital and will greatly benefit from plans to improve the Tottenham Court Road tube station and create a Crossrail station there.' by Richard Waite
