International Commerce Centre, Hong Kong, China, 2010 designed by KPF

The tower’s subtly tapered re-entrant corners and the gently sloped curves at its base are designed to optimize its structural performance. These curves splay out at the base of the tower, rooting the tower in its surroundings, while creating sheltering canopies on three sides, and a dramatic atrium on the north side. -- architect's web site

However, although the tower’s vertical form may steal the spotlight, special attention was also placed upon the ground life of the tower. Situated on a busy site, surrounded by an elevated motorway viaduct and on top of a convergence of public transport facilities, the tower’s lower portion extends its horizontality in order to “relate to the extreme horizontal energy of pedestrian, automobile, tram and shipping movements at ground level. -- ArchDaily

The architects bring their innovative approach to the structural systems: rather than being concealed behind a building’s façade they are articulated and become significant parts of the design. An architectural theme reoccurring throughout the site is the use of red steel tubes. The tubes cascade down the side of the Observation Tower to form a canopy for the Amphitheater stage and also frame the Main Grandstand. Evocative of sports cars and movement, this element ties the structures together creating a consistent visual experience. -- ArchDaily
