Here are some images of architects Herzog & de Meuron’s extension to the Tate Modern art gallery in London, which was recently granted planning permission. The extension will add a new wing and also convert the underground tanks (below),which previously used to store oil for the former power station, into new galleries.
The extension will provide display and exhibition spaces, performance spaces, education and learning facilities, together with ancillary offices, catering, retail and associated support facilities on 24,786 m2 new space.
