Architectural features of Burj Khalifa;

The central part of the building is a large-scale mixed-use development project, including offices, retail market space, residential units and a giorgio armani hotel. The Y-shaped plane broadens the horizon facing the Arabian Gulf to the greatest extent. On the ground, skyscrapers are surrounded by green spaces, waterscape and pedestrian-friendly avenues.

The overall design of the building is inspired by a unique geometric figure of Desert Flower in this area, and its pattern structure has influenced many Muslim buildings. It consists of reinforced concrete and glass curtain wall, and carved bricks form its shape around the central support core. Because the building is built from a flat base, the outer surface deviates inward in an upward spiral structure, which reduces the building volume when it touches the sky.

At the highest point, the central core appears and forms the spire.

In addition to its record-breaking height, Burj Khalifa also combines new structural efficiency with architectural efficiency to reduce material consumption and waste generation. This includes a ventilation system from the air, so that cool and dry wind can be introduced into the building from the spire. At the same time, it also has the largest condensed water recovery system in the world.
