The purpose of the project is to provide much needed up to date office accommodation and facilities for Members of Parliament in the long term. Parliament House is nearly 160 years old but was never completed. It was originally built with little or no office accommodation with dozens of ad hoc temporary offices being added over time. The new building will be constructed within the eastern gardens of Parliament House and provide 110 offices for Members. The pincer-shaped structure will be partly sunken and feature a rooftop garden and large central courtyard to integrate the building into the surrounding established landscape.
