Petronas Towers, Malaysia
What used to be the world’s tallest towers may have been overthrown by other super skyscrapers since 2004 but the Petronas Towers still stand as the tallest twins in the sky. They form the central element of the Kuala Lumpur City Centre, Malaysia and are known all over the world for their signature iconic standard in skyscraper history. The plan of the towers is generated from two overlapping squares that form an octagonal star, a pattern frequently found in Islamic design.
As the buildings rise, they step back six times, and at each setback, the walls tip outward slightly, adding complexity reminiscent of traditional Malaysian architecture. The towers are clad in panels of glass and stainless steel that softly reflect sunlight, typical of any soaring tower. Between the two towers is a powerful, figural void. To activate this space, the center of the composition, a two-story bridge was added at the 41st and 42nd floors. Two stories. One has got to appreciates the strides in engineering made in this design. The bridge is structured by angled brackets that shape the space and accentuate the vertical thrust of the towers. This sky lobby connects the buildings and contains spaces shared by both, including elevator lobbies, a conference center, and a prayer room.
