Here are new images of architects Herzog & de Meuron's extension to the Tate Modern art gallery in London, which was recently granted planning permission.
More details plus images of the architects earlier design for the extension in our earlier story.
The extension will add a new wing and also convert underground tanks (below), previously used to store oil for the former power station, into new galleries.
