Tate Modern's proposed £215m extension has been given the green light by planners, the London gallery has said.
The 11-storey, brick and glass structure - designed by Swiss architects Herzog and de Meuron - will increase capacity at the gallery.
Southwark Council approved the revised project for the extension which is expected to be completed in 2012.
Tate Modern said £74m had already been raised towards the extension - a third of the overall cost.
Tate director Sir Nicholas Serota said he was "delighted" the plans had been approved.
