And 432 Park Makes 100

CTBUH defines a supertall as a skyscraper that is at least 300 meters (984 feet) tall. The slender residential tower at 432 Park Avenue designed by Rafael Viñoly Architects tops out at 425.5 meters (1,396 feet), well over the benchmark. Although it won't be occupied until later this year, this height makes 432 Park (for now) the tallest all-residential tower in the world, according to CTBUH.

More amazing than the news that there are 100 supertalls completed to date is the fact there are more than 100 "topped out or under construction that are scheduled to be completed in the next five to six years." In 2010 there were 50 supertalls, and with the number of supertalls expected to be 200 in another five years time, they are doubling every five years! At this rate we should expect 400 supertalls by 2025 and 800 supertalls by 2030.

With even a fraction of that number completed by 2030, the furvor over supertalls most likely will subside, replaced by attention directed at "megatalls," what the CTBUH defines as skyscrapers over 600 meters (1,968 feet). Only three megatalls have been completed to date, but the CTBUH expects four more to be completed in the coming years, including AS+GG's Jeddah Tower. By then the 100-supertall milestone will be just a faded memory.
