A £215M extension is being built at the Tate Modern gallery on London’s South Bank as part of the Transforming Tate Modern renovation project
The new building will rise 65m above the ground. It will offer 21,000m² of new space spread over 11 storeys, including additional gallery space alongside performance spaces, education spaces, shops, cafés and new terraces, as well as new offices.
The design takes the shape of an irregular pyramid. Architects Herzog & de Meuron were eager to keep much of the industrial feeling of the old structure, which was converted from the 1940s Bankside power station.
The original design for the project featured a glass façade which was less well integrated with the main gallery building. The design was revised to retain the former power station’s oil tanks as exhibition spaces.
