THE DESIGN
The floor-plate of the Tower is designed based on geometric patterns common in architecture of Islamic heritage. It is composed of two rotated and superimposed squares with small circular infills. These geometric figures have been described by architects as symbolizing unity, harmony, stability and rationality - all important principles of Islam.

Like the exterior design, the Towers' entrance design was also inspired by the country's cultural heritage, incorporating contemporary Malaysian motifs adapted from traditional handicrafts such as "songket" and timber carvings. The overall character of the building is high-tech and international but distinctively Malaysian.
