When our architects, Haworth Tompkins, were working on a Conservation Management Plan for the National Theatre they made sure to balance the current needs of our Grade II* listed building while making it fit for the 21st century. They assessed the architectural significance of the site and provided a framework for any changes to the building. The plan concluded that there was a current material risk to the theatre's infrastructure which could not be addressed via annual capital funds.

From this, the architects developed a Masterplan to address the problems of the aging building combined with our ambitions for the future: ensuring we improve our artist facilities, engage more people, and make the National Theatre environmentally and financially sustainable.

This cost-effective scheme was created whilst consulting with neighbouring organisations on the South Bank and local residents; with English Heritage, the Twentieth Century Society and the Theatres Trust; with members of staff and the NT's artistic community; and with our audience. The plan was widely approved by these groups and granted planning consent by Lambeth Council on 29 September 2010.
