The global count of Supertall Skyscrapers reaches 100 with completion of 432 Park Avenue in New York

Following the completion of 432 Park Avenue in New York City in the USA there are now officially 100 supertall (300-plus-metre) skyscrapers in the world.

The construction of supertall buildings has increased at a rapid rate in recent years, as the global tall building industry continues to grow at speed. Architects, engineers, and developers have raced to begin building towering structures, transforming the definition of modern skyscrapers

The first 50 supertalls took 80 years to complete between 1930 and 2010, however in the last five years alone another 50 have been added to the list.

The majority of new supertall skyscrapers can be found Asia and the Middle East, mirroring construction trends that have emerged over the past decade, but New York has remained an active centre for supertall construction in the Americas. With the completion of 432 Park Avenue – the city’s seventh – New York now has the second-highest number of supertall skyscrapers in the world. Meanwhile, Dubai leads the list with 18.

The Council on Tall Buildings Urban Habitat (CTBUH), a non-profit based at the Illinois Institute of Technology in the USA, officially confirmed 432 Park Avenue’s completion date to be December 23, 2015. At 425.5 metres, it is the tallest all-residential building in the world and the 14th-tallest overall. With a 1:15 slenderness ratio, the tower typifies the ‘superslim’ typology that has been made possible by advances in lateral resistance technology. These buildings are particularly prevalent in dense urban areas such as New York, where limited land availability and soaring luxury residential prices justify their development.

Supertall construction is poised to remain strong in the coming years. According to CTBUH data, there are well over 100 supertall skyscrapers topped out or under construction that are scheduled to be completed in the next five to six years. That includes Jeddah Tower, which will become the world’s tallest building and the first kilometre-high building upon completion.

With supertall skyscrapers becoming increasingly common, many look to the megatall (600-plus-meter) distinction as the new frontier for the world’s tallest buildings. There are currently only three completed megatall buildings in the world, but that number is set to more than double in the coming years as four more – including Jeddah Tower – complete.
