How much did Parliament House cost to build?

Hi Eve. 

Australian Parliament House cost $1.1 billion to build. This reflects the buildings huge size and the complex work needed to construct it.  

Parliament House is one of the largest buildings in the Southern Hemisphere. Built into Capital Hill, workers removed 1 million cubic metres of earth and rock. It was replaced with 300,000 cubic metres of concrete and 24,000 tonnes of steel to support the structure. The finished building is 300 metres long and 300 metres wide with 250,000 square metres of floor space. It contains 4,500 rooms, 22 kilometres of corridors, 17 internal courtyards and an 81-metre-high stainless-steel flagpole. More than 10,000 people helped build it, using almost entirely Australian materials. Today, when Parliament meets, between 4,000 and 5,000 people work inside the building. Australian Parliament House was designed to serve Australia for at least 200 years showing the scale and importance of the project.
