Petronas Twin Towers

"The Petronas Twin Towers was designed by Cesar Pelli & Associates (USA) in association with KLCC architects. The tower's floor plate design is based on simple Islamic geometric forms of two interlocking squares creating a shape of eight-pointed stars. Upon the eight-pointed stars, are eight superimposed semi-circles softening the inner angles. These semicircles are themselves anchored by the arcs of the main structural columns of the buildings. The semi-circles were superimposed in the inner angles of the interlocked squares to create more usable floor space. The design details continued to dictate the way in which the buildings would rise in as graceful a fashion as possible. To maintain the vertical axis and tapering of the design, each tower is set back five times in its ascent. Architecturally, these forms reflect the paramount Islamic principles of 'unity within unity, harmony, stability and rationality'".
