The central business district of Perth is bounded by the Swan River to the south and east, with Kings Park on the western end, while the railway reserve formed a northern border. A state and federally funded project named Perth City Link sunk a section of the railway line, to allow easy pedestrian access between Northbridge and the CBD. The Perth Arena is a building in the city link area that has received several architecture awards from various institutions such as the Design Institute of Australia, the Australian Institute of Architecture, and Colorbond. St Georges Terrace is the prominent street of the area with 1.3 million m of office space in the CBD. Hay Street and Murray Street have most of the retail and entertainment facilities. The tallest building in the city is Central Park, which is the eighth tallest building in Australia. The CBD until 2012 was the centre of a mining-induced boom, with several commercial and residential projects being built, including Brookfield Place, a office building for Anglo-Australian mining company BHP Billiton.
