in white concrete, since painted, except for a pedestal of bricks left with their natural colour. The original roofs were constructed of flat concrete slabs with a membrane waterproofing and finished with a bituminous coating which was designed to be walked on. At the roofline, on either side of the main entrance, are large painted reliefs of the Royal and Commonwealth coats of arms. The railings on the front steps were installed after the federal parliament had left the building and were not present during its active lifetime. The interior continues the stripped-classicism of the exterior, with the use of common motifs and simple lines, in both the decor and furnishings. To represent the federal nature of the Commonwealth of Australia, the building also makes extensive use of timbers from various parts of Australia, with a timber native to each state, (except South Australia), being used for different purposes. The building is also designed to make good use of natural light from windows, skylights and light-wells. Maintenance and restoration activities are being performed as detailed in a Heritage Management Plan. Plan In keeping with its classicised forms, the building has strong symmetrical planning based on a number of major spaces. The major axis through the building, which is part of the land axis of Walter Burley Griffin and Marion Mahony Griffin's design, is through King's Hall, the Parliamentary Library and the dining rooms at the back. The cross-axis features the House of Representatives and Senate chambers on either side of King's Hall. Originally having an H-shape, the building now forms a large rectangle as a consequence of various extensions, with a small rear projection. The building now contains four courtyards and some light-wells. The courtyards are surrounded by colonnades at ground level and (now enclosed) verandas on the main floor. At the centre is King's Hall. It is named for King George V, whose statue is in the room. Directly adjacent to King's Hall are the chambers of the House of Representatives (to the south-east) and the Senate (to the north-west). To the rear is the Parliamentary Library (occupied from 1998 to 2008 by the National Portrait Gallery) and behind it the dining rooms. The rest of the main floor of the building was given to offices and meeting rooms. On either side of each of the parliamentary chambers are meeting rooms for the government and opposition parties and—at the
