Denys Lasdun and the architecture of the National Theatre

With Barnabas Calder, University of Liverpool, a historian of architecture specialising in British architecture since 1945, Patrick Dillon of Haworth Tompkins, the project architect of NT Future (the National's redevelopment project which will transform facilities) and Catherine Croft, Director of the Twentieth Century Society.
