The building has received criticism for the way in which its design discourages collegiality amongst members. New Parliament House was designed in the late 1970s, in the context of the Sydney Hilton Hotel bombing and the tense political climate following the Dismissal of the Whitlam Government, and thus one of the key elements of the design brief was providing security for the executive. The winning design's solution was to fence off the executive in its own ministerial wing. In practice, this meant it was no longer possible for backbenchers to bump into ministers while passing through the corridors of parliament, increasing a sense of detachment between the two groups. The heart of Old Parliament House was King's Hall, an entrance hall open to the public that connected the House of Representatives and the Senate to the parliamentary library and the refreshment rooms. Inevitably, due to its central location, Kings Hall became a bustling hub where people met and talked, and a place where politicians could mingle with the public and the press gallery. In contrast, the new building situates the library and refreshment rooms at great distance from the two Chambers, and Member's Hall, the foyer that connects the House and the Senate, is not open to the public. As a consequence, Member's Hall lies empty, as parliamentarians have no reason to be there.
