a great glass roof over the existing three buildings. This did not proceed due to the high degree of National Lottery funding required and likely high cost. 2000s In 2000, a masterplan for the South Bank Centre site was produced. The main features were a new administration building for members of staff the removal of access for delivery vehicles to the south of the Hungerford Bridge approach viaduct and east of the Hayward (by Waterloo Bridge); the creation of three new public spaces around the RFH (Festival Riverside, Southbank Centre Square and Festival Terrace); modification of the Queen Elizabeth Hall undercroft and the lower two levels of the Hayward to provide a frontage onto Southbank Centre Square; and a new British Film Institute building partly underground on the Hungerford Car Park site. In line with the plans, in 2006-7 a new glass-fronted building was created to provide office space for Southbank Centre staff as well as a range of new shops and restaurants. This was inserted between the RFH and the approach viaduct to Hungerford Bridge. New restaurants and shops along the low level Thames elevation of the Royal Festival Hall replaced an earlier cafeteria area and accompanied pedestrianisation of this frontage, achieved by removing the circulation road. Between 2005 and 2007 the Festival Hall auditorium was modified, the natural acoustic enhanced to meet classical music requirements. Seating was also reconfigured, together with upgrades to production facilities and public areas, with provision of new bar areas, the removal of most shops from foyer spaces, and refurbished lifts and WCs. 2010s In early 2013 the Southbank Centre unveiled plans, which soon became a source of vigorous debate, for alterations to the Hayward Gallery and Queen Elizabeth Hall dubbed the "Festival Wing", funded by Arts Council England. The proposal would have provided arts spaces in a new high level L-shaped building linking the Hayward Gallery and Purcell Room buildings and with a wing running parallel to Waterloo Bridge behind the Queen Elizabeth Hall auditorium. Its features were to include a glass pavilion, new arts spaces, a literature centre, cafes and commercial units. The proposed alterations would have replaced the skate park which has developed in the undercroft, hailed as the birthplace of British skateboarding, with retail units to fund the new arts spaces. By May 2014, the campaign group strongly opposing the proposals called Long Live Southbank had gained over 120,000 members.
