The 12-storey tower provides teaching, learning, research and office accommodation for 1,256-1,300 students and 300-326 academic staff. The building's design is based on the idea of a tree-house structure.The building's façade, which was made of 320,000 custom designed bricks, is described as the "squashed brown paper bag". Frank Gehry said, "Maybe it's a brown paper bag, but it's flexible on the inside, there's a lot of room for changes or movement."An entrance from The Goods Line - a pedestrian pathway - is located on the eastern border of the site.ConstructionEarly works on site and archaeological excavation were carried out from late 2011 until early 2012. The building was constructed by Lend Lease Group which was appointed in November 2012. It is estimated that 320,000 custom-designed bricks were used for its construction.
