Editing Tate Modern (section)

=== Initial redevelopment ===
For many years after closure Bankside Power station was at risk of being demolished by developers. Many people campaigned for the building to be saved and put forward suggestions for possible new uses. An application to [[listed building|list]] the building was refused. In April 1994 the [[Tate]] Gallery announced that Bankside would be the home for the new Tate Modern. In July of the same year, an international competition was launched to select an architect for the new gallery. Jacques Herzog and Pierre de Meuron of [[Herzog & de Meuron]] were announced as the winning architects in January 1995. The £134&nbsp;million conversion to the Tate Modern started in June 1995 and was completed in January 2000.<ref name="auto">{{cite web|url=http://www.yourlocalguardian.co.uk/news/local/10439829.Tate_Modern_builders_win___400m_Battersea_Power_Station_contract/|title=Tate Modern builders Carillion win £400m Battersea Power Station contract|publisher=Your local Guardian|date=23 May 2013|access-date=27 September 2013}}</ref>

The most obvious external change was the two-story glass extension on one half of the roof. Much of the original internal structure remained, including the cavernous main turbine hall, which retained the overhead travelling crane. An [[electrical substation]], taking up the Switch House in the southern third of the building, remained on-site and owned by the French power company [[EDF Energy]] while Tate took over the northern Boiler House for Tate Modern's main exhibition spaces.<ref name="auto" />

The history of the site as well as information about the conversion was the basis for a 2008 documentary ''Architects Herzog and de Meuron: Alchemy of Building & Tate Modern''. The conversion work was carried out by [[Carillion]].<ref name="auto" />
