There are several ironies in the news that the BBC is considering moving its central London operation to a site adjacent to the Foster & Partners' Greater London Authority headquarters. If Norman Foster ends up designing the building for them, which must be a possibility given that the firm is commissioned to do the entire scheme, it will be back to square one. Foster won the 1980s competition to revamp the BBC building at the bottom of Langham Place, only to see the corporation abandon the scheme in an attack of fright over the highly economical £20 million price tag. Instead it moved staff out to the hated White City Lubyianka and sold the London building for a hotel conversion. Meanwhile, whatever will happen to Bush House, where Foster and Will Alsop have been battling it out in a design competition for the Beeb? That exercise is presumably to establish new value for the site. Astragal's tip is that it will end up in the hands of the London School of Economics, which is itself embarking on a major regeneration scheme. Architect (natch) is N Foster.
