4th floor bridge
London’s Tate Modern gallery has undergone a big expansion. It’s now home to Switch House, a capacious 10-storey extension. But it’s been connected to the existing core of the building by new walkways. The new 4th floor bridge gives you a new, heightened perspective on the vast Turbine Hall, home to huge installations where the Tate’s industrial past blasts through. Here are just two architectural views from a new viewpoint.
