Situated in the Kuala Lumpur the capital of Malaysia sits the Petronas Twin Towers. The Petronas Twin Towers were the tallest buildings in the world until Taipei 101 was completed in 2004. The Petronas Twin Towers remain the tallest twin buildings in the world. Designed by Argentine architects César Pelli and Djay Cerico under the consultancy of Julius Gold, the Petronas Towers were completed in 1998 after a seven year build and became the tallest buildings in the world on the date of completion
The 88-floor towers are constructed largely of reinforced concrete, with a steel and glass facade designed to resemble motifs found in Islamic art, a reflection of Malaysia's Muslim religion. Another Islamic influence on the design is that the cross section of the towers is based on a Rub el Hizb (albeit with circular sectors added to meet office space requirements) Due to a lack of steel and the huge cost of importing steel, the towers were constructed on a cheaper radical design of super high-strength reinforced concrete. High-strength concrete is a material familiar to Asian contractors and twice as effective as steel in sway reduction; however, it makes the building twice as heavy on its foundation than a comparable steel building. The overall cost of this building was 1.6 billion dollars
The towers feature a skybridge between the two towers on 41st and 42nd floors, which is the highest 2-story bridge in the world. It is not attached to the main structure, but is instead designed to slide in and out of the towers to prevent it from breaking during high winds. The bridge is 170 meters above the ground and 58 meters long, weighing 750 tons. The same floor is also known as the podium, since visitors desiring to go to higher levels have to change elevators here. The skybridge is open to all visitors, but free passes (limited to 1700 people per day) must be obtained on a first-come, first-served basis. Visitors are only allowed on the 41st floor as the 42nd floor can only be used by the tenants of the building. The skybridge also acts as a safety device, so that in the event of a fire or other emergency in one tower, tenants can evacuate by crossing the skybridge to the other tower
Next to the Petronas Twin Towers is the premier shopping mall of Kuala Lumpur City Center - Suria KLCC. The design of the mall utilizes maximum skylight form the spacious center court for natural lighting, to befit the name Suria KLCC (Suria means sunshine). Its huge 6-level crescent shaped shopping mall contains over 200 shops of specialty stores, 3 departmental stores, fashion boutiques, cinemas, a 1200-seat food court on the second floor and a 300-seat local food court and theme restaurants on the fourth floor. At the ground floor of Suria KLCC there are several cafes facing the beautiful KLCC Park
Outside Suria KLCC is the 20-hectare KLCC Park. The KLCC Park includes a Symphony Lake with its 2 playful musical fountains at the esplanade just outside Suria KLCC. A 2-acre kiddie playground with colourful child-safe play equipment, a public wadding pool, patterned footpaths and a soft and well design jogging track. Close to 2000 indigenous trees from 74 species are planted in the KLCC park.
