In 2008, Transport for London (TfL) announced a project to provide step-free access to all three lines in advance of the 2012 London Olympics. The project also included the construction of a new entrance on the south side of Piccadilly with ramped access directly from Green Park. Work commenced in May 2009 to install two lifts from the ticket hall to the Victoria line platforms and the interchange passageway to the Piccadilly line. This work and a third lift in the new park-side entrance between the street level and the ticket hall were completed ahead of schedule in 2011. At the same time, Green Park station underwent a major improvement programme which saw the tiling on the Victoria and Piccadilly line platforms and the interchange passageways replaced. When the Jubilee line opened, the Hans Unger tiling in the seat recesses of the Victoria line platforms was replaced with a design using the leaf patterns used on the Jubilee line platforms; the Unger design was reinstated during the restoration.
