sometimes with their original furnishings. The three best-preserved interiors, other than King's Hall and the Chambers, are the Government party room (on the House of Representatives side), the Senate club room (also called the Senate Opposition party room) and the Clerk of the Senate's office (which was originally the President of the Senate's office). All retain their original fittings and furnishings, designed by Murdoch and his team in accordance with the simplified classical design scheme. These are characterised by simple forms, based on Murdoch's square motif. The original building was small and did not provide individual offices for all members. To an extent, this was to be mitigated by ministers having offices in their own departments, originally in the east and west blocks (also designed by Murdoch). For this reason, the party rooms are not just meeting rooms but contain private phone booths, washbasins, desks and small areas for more intimate discussions. Gardens Originally, the rear courtyards of the building were open to the gardens through a colonnade, Murdoch's intention being that members and Senators should be able to use the gardens as an integral part of the building. Later this intention was lost, as extensions were added to the back part of the building to provide more offices. Murdoch also envisaged the adjacent gardens as a continuation of the House’s courtyards. These parliamentary gardens are situated on either side of the building, they are enclosed by hedges and contain minimal trees. In both cases, each garden has been divided into four quadrants, with two being occupied by rose gardens and the remaining two by recreational facilities. On the Senate side, these are tennis courts and a cricket pitch. On the Representatives' side, they are tennis courts and a bowling/croquet green. In the 1970s much of the Representatives' gardens were covered by an annex extension to the main building, but this has now been removed and the gardens have been restored. The official reopening was in 2004. The rose gardens contain a wide variety of specimens, including many old roses and roses donated by prominent Australians and overseas bodies and individuals. Much of the inspiration (and organisation) for this came from the Usher of the Black Rod and later Clerk of the Senate, Robert Broinowski, and the gardens were designed by Rex Hazlewood. They also played major roles in the development of the National Rose Gardens on the other side
