140 St Georges Terrace (Perth, WA)

 office building, skyscraper, parking

140 St Georges Terrace is a skyscraper in Perth, Western Australia, Australia. The 30-storey building has a height of 131 m (430 ft). The building was constructed from 1972 until 1975. The site was formerly occupied by the AMP Chambers building which stood from 1914 until 1972. The building was the tallest in Perth from 1975 to 1976. It was formerly named the AMP Building after its tenant, AMP, who occupied the building from 1975 until 2003. The floor area is 29,800 sq m (321,000 sq ft). The building has an underground car park with 260 spaces. 140 St Georges Terrace features a service core design, with the concrete core containing 12 passenger lifts, one service lift, and two stairwells. The perimeter of the square tower features load-bearing columns, allowing the office floors to remain mostly column-free. An observation deck was located on the 29th floor which was closed following the construction of the BankWest and Central Park Towers.

140 St Georges Terrace underwent a minor cosmetic refurbishment in 1992 which involved a facelift for the ground floor lobby, including polished granite flooring, wall panelling, coffered ceilings with concealed lighting, improved revolving doors, new glass, planter boxes, the repaving of the building's forecourt with cobblestone, new landscaping, further public seating, and the integration of the building's underground parking with that of Central Park. Despite the refurbishment, the building was still in need of an upgrade by 2000. An extensive refurbishment was undertaken from 2003 to 2005 at a cost of $43,000,000. This refurbishment was mostly internal; the office floors were refurbished, the air conditioning and lifts were repaired, and new conference facilities were added. The bulk of the facade remained unchanged, aside from a new two-storey high, 15-metre long bronzed-glass canopy at ground level. The glass of the canopy is coated with small white dots which have a shading effect during the day, but uplighting produces a white ceiling effect at night. This canopy was intended to give the tower a more prominent entrance.

A sculpture entitled "The Black Stump" was located in the building's forecourt from 1975 until 1990, when it was relocated to the University of Western Australia beside the Octagon Theatre. The refurbishment was designed by architects Cox Howlett & Bailey Woodland, with the contract won by Multiplex. The refurbishment was a success, with the building going from sparsely occupied at the start of the refurbishment project to practically full in 2006. The refurbishment was also expected to give the tower a "4.5 Australian Building Greenhouse Rating" due to its new, energy-efficient lifts, air conditioning, window tinting and double glazing.
