Bankside Power Station was transformed into Tate Modern by the Swiss architects Herzog & de Meuron and opened in 2000. The former Turbine Hall, running the whole length of the vast building, now marks a breathtaking entrance to the gallery. An escalator sweeps through two floors featuring a cafe, shop and auditorium to three levels of galleries. At the top of the building is a two-storey glass roof which not only provides natural light into the galleries on the top floors, but also houses a stunning cafe offering outstanding views across London, including St Paul’s Cathedral and the London Eye. A lightweight luminous roof, fabricated from translucent panels, at night this beacon is a unique addition to the London skyline. Level 2 has large open spaces with statues and overlooks the imposing entrance slope. The North entrance to Level 2 looks onto St Paul's Cathedral, with a landscape area overlooking the river. Level 1 is the famous Turbine Hall. The East Room is a self-contained space which can double as an office or penthouse apartment. The Blavatnik Building opened in 2016 offering more gallery space, a members’ room and a public viewing platform with 360 degree views over London. Additionally Tate Modern offers wide, modern, light corridors; a red auditorium; a compound that can accommodate vehicles and an area of the river landscape that can hold a small unit base.
