Petronas Twin Towers

The 88-story PETRONAS Twin Towers is located at the North-west corner of the 100-acre development, the Towers standing majestically at 452 metres. According to the CTBUH's official definition and ranking, they were the tallest buildings in the world from 1998 to 2004 until surpassed by Taipei 101.^[2] The buildings are the landmark of Kuala Lumpur with nearby Kuala Lumpur Tower.

The design, created by renowned architect, Cesar Pelli & Associates of the USA was selected through an international design competition held in 1991.

The floor plate of the Towers is based on geometric patterns common in architecture of Islamic heritage. It is composed of two rotated and super imposed squares with small circular infill around the edges. The exterior of the PETRONAS Twin Towers is organised in horizontal ribbons of vision glass and stainless steel which glint and shimmer in the sun. The design of the buildings also incorporates set-back at level 60, 73, 82, 84 and 88. Attached to each Tower is the 44-story side tower or annex, which provides an architectural balance to the slender profile of the main Tower. These coreless annexes also provide additional office space.

The Like the exterior design, the interior design patterns and materials used also reflect the national identity of Malaysia. The Towers' entrance lobbies are showcase of the country's cultural heritage, incorporating contemporary Malaysian motifs adapted from traditional handicrafts such as 'songket' and timber carvings while the floor design has been laid in a popular 'mengkuang' weave mat design.

A 58.4 metre sky bridge at levels 41 and 42 links the Twin Towers. The unique double-deck sky bridge stands 170 metres above street level with its arch support forming a symbolic gateway to the city centre.
