Earlier this week Sir Nicholas Serota, director of the Tate Modern, announced that Herzog & de Meuron's extension will officially open on Friday 17th June 2016. The gallery, which originally opened in 2000 housed within a former power station in London's Bankside, dramatically transformed the UK's relationship with modern and contemporary art. Since then, the Tate Modern has become a bastion of trend-setting and high-profile exhibitions, and has grown to be one of London's most visited cultural venues.
According to Serota, "the new Tate Modern will challenge the traditional story of modern art and offer a fresh perspective on artists working around the world in a re-hang of the whole building. It will also be a communal place where people can meet to share, debate and create," he added.
The Architects' Journal have reported that "the original estimated project cost of £215 million in 2012 has risen to £260 million [today]." The Tate still has yet to raise £30 million to reach the upper target of the latest costings.
