Burj Dubai

Burj Dubai is a supertall skyscraper under construction in Dubai, United Arab Emirates, is the tallest man-made structure ever built, at 818 m (2,684 ft)
According to Marshall Strabala, an SOM architect who worked on the building's design team, Burj Dubai was designed based on the 73-floor Tower Palace Three, an all-residential building in Seoul, South Korea. In its early planning, Burj Dubai was intended to be entirely residential.
The tower is composed of three elements arranged around a central core. As the tower rises from the flat desert base, setbacks occur at each element in an upward spiralling pattern, decreasing the cross section of the tower as it reaches toward the sky. There are 26 terraces in Burj Dubai. At the top, the central core emerges and is sculpted to form a finishing spire. A Y-shaped floor plan maximizes views of the Persian Gulf. Viewed from above or from the base, the form also evokes the onion domes of Islamic architecture. During the design process, engineers rotated the building 120 degrees from its original layout to reduce stress from prevailing winds.
