The Petronas Towers are the centre piece of the mixed-use Kuala Lumpur City Centre (KLCC) complex, set in the heart of the commercial district of the city. Rising 452 metres, the towers were certified the world’s tallest buildings by the Council of Tall Buildings and Urban Habitat in 1996.


The complex is at the forefront of technology, with a form derived from an Islamic pattern, and extensive use of local materials. The towers have become a popular example of contemporary architecture in Malaysia, and their elegant form makes them the country’s most significant urban landmark.

In 1981, Malaysian Government undertook the development of a 40-hectare site in the heart of Kuala Lumpur’s emerging business district – the ‘Golden Triangle’. In 1991 an international competition was held for the design of the office tower complex and was won by Cesar Pelli & Associates.


The project design is based on the concept of two interlocking squares that form an eight-pointed star modified by placing eight semicircles in the angles of the corners to create more floor space. Each tower rises eighty-eight storey and provides 218,000 square metres of floor space, including an additional circular ‘bustle’ or annex forty-four storey high. The towers taper at six intervals, with the walls of the upper levels sloping inwards. Both towers are topped by a conical spire and a 73.5-metre-high pinnacle.

The structure supporting each of the towers comprises a ring of sixteen cylindrical columns of high-strength reinforced concrete, placed on the inner corners of the star-shaped plan to form a ‘soft tube’, with the columns linked by arched ring beams, also made of structural concrete.


The towers are connected at the forty-first and forty-second levels, 170 metres above street level, by a sky bridge, enabling intercommunication between the towers. The structural design of the sky bridge was complex because it had to accommodate differing movements from each tower. The towers are also joined at their base to form a six-level retail and entertainment complex with a central atrium.


From the atrium, two ‘streets’, lined with over 300 shops, cafés and restaurants, extend along opposite axes. In addition, the complex includes an 880-seat concert hall, an art gallery, a specialized library and an interactive science discovery centre, as well as a four-storey underground car park for 5,400 cars.


Petronas Towers complex combine modern technology with a sense of cultural identity. It has also introduced new architectural standards to Malaysia in terms of design, construction and technology. The building has become an icon that expresses the sophistication of contemporary Malaysian society and builds on the country’s rich traditions to shape a world city.
