Dubai has a rich collection of buildings and structures of various architectural styles. Many modern interpretations of Islamic architecture can be found in Dubai, due to a boom in construction and architectural innovation in the Arab World in general, and in Dubai in particular, that has been supported by the top architectural and engineering design firms of New York and Chicago. As a result of this boom, modern Islamic - and world - architecture has literally been taken new levels in the last decade in skyscraper building design and technology, culminating in 2010 with the completion of the Burj Khalifa (Khalifa Tower), now by far the world's tallest building at 828 m (2,716 feet). The Burj Khalifa's design is derived from the patterning systems embodied in Islamic architecture, with the triple-lobed footprint of the building based on an abstracted version of the desert flower hymenocallis which is native to the Dubai region. The completion of the Khalifa Tower, following the construction boom that began in the 1980's, accelerated in the 1990's, and took on a rapid pace of construction unparalled in modern human history during the decade of the 2000's, left Dubai with the world's tallest skyline as of January 4, 2010.
