After Parliament relocated to the new building, there was a debate on whether to demolish Old Parliament House. During the 1920s it had been argued by some, including Walter Burley Griffin, that the building's position would interfere with the vista of a permanent Parliament House. Burley Griffin had likened the placement of the Old Parliament House to 'filling the front yard with outhouses' as the building would interfere with the land axis from Mount Ainslie to Capital Hill. After considering the building's historic significance in the history of twentieth century Australia, the government decided that it should remain. However, it remained unclear what its future purpose would be. In the end it was decided that its most suitable use would be a 'living museum of political history.' The building was re-opened in December 1992. It is now an Executive Agency of the Department of the Prime Minister and Cabinet, run as a museum.
