All flooring is made from lightweight movable panels, under which you can find a comprehensive network of power, telecommunication, and air-conditioning systems. Hence installation of equipment or computer terminals becomes far easier.
The requirement to build in excess of one million square feet in a short timescale suggested a high degree of prefabrication, including factory-finished modules, while the need to build downwards and upwards simultaneously led to the adoption of a suspension structure, with pairs of steel masts arranged in three bays. As a result, the building form is articulated in a stepped profile of three individual towers, respectively twenty-nine, thirty-six and forty-four storeys high, which create floors of varying width and depth and allow for garden terraces. The mast structure allowed another radical move, pushing the service cores to the perimeter so as to create deep-plan floors around a ten-storey atrium. A mirrored sunscoop reflects sunlight down through the atrium to the floor of a public plaza below a sheltered space that at weekends has become a lively picnic spot. From the plaza, escalators rise up to the main banking hall, which with its glass underbelly was conceived as a shop window for banking.
