This is one of a series of drawings made for George 'Grey' Wornum to illustrate his scheme for the redesign of Parliament Square after the Second World War. These drawings have been made directly onto photographs of the site. This is an effective method for showing how additions or amendments will impact on an existing site.
Parliament square was a key example of the type of public space which was the subject of great attention just after the war. Much criticism was aimed at spaces that did not allow public gatherings or leisure, and effort was channelled to ensure that spaces created as part of post-war reconstruction were 'sociable'.
