Nine towers with cantilevered hazardous positions Cantilevers are structural components that, when extended horizontally from another volume and supported at just one end, provide an eye-catching, visually arresting impression that defies gravity. The world's longest cantilever, which is now 67.5 metres long, extends from One Za'abeel, a newly finished mixed-use building in Dubai, between the two towers. It almost defeats the 66.5-meter-long observation deck at Marina Bay Sands in Singapore for the title.

These two technical marvels are included in our list of nine skyscrapers, or structures taller than 150 metres, that are characterised by perilously positioned cantilevers. Nikken Sekkei, "One Za'abeel, United Arab Emirates" The world's longest cantilever, located at One Za'abeel in Dubai, protrudes 67.5 metres over a six-lane road. It is a component of The Link, a striking 230-meter-long sky bridge positioned between the development's two buildings.

At the end of the cantilever, a glass floor designed by the Japanese architectural company Nikken Sekkei allows people with the courage to look through its diagrid structure to the ground 100 metres below. Nikken Sekkei, "One Za'abeel, United Arab Emirates" Standing 67.5 metres over a six-lane Dubai highway, the cantilever of One Za'abeel is the longest in the world. It is a component of The Link, a striking 230-meter-long sky bridge positioned between the development's two buildings. Japanese studio for architecture At the end of the cantilever, Nikken Sekkei installed a glass floor that allows people with the courage to see through its diagrid construction to the earth 100 metres below. Moshe Safdie's Raffles City, Chongqing, China Another example of a cantilever by Safdie Architects is this glass-bottomed public observation platform in China's Raffles City complex. It starts at one end of The Crystal, a glass and steel sky bridge that connects the complex's four buildings and spans 300 metres. The remainder of The Crystal consists of a variety of 250-meter-high gardens, pubs, and eateries, in addition to a resident clubhouse and hotel lobby.

OMA, CCTV Headquarters, China OMA created a distinctive design known as 'big pants' by connecting two buildings at the CCTV Headquarters in Beijing with a cranked bridge that lacks end support. The structure, which houses the state-owned China Central Television's headquarters, was intended to encourage circulation across blocks rather than divide people into distinct spaces as typical skyscrapers do. "An explicit ambition of the building was to try to hasten the end of the skyscraper as a typology, to explode its increasingly vacuous nature and loss of programme, and to refuse the futile competition for height," Koolhaas previously said. USA's 30 Hudson Yards, by KPF According to its architect, Kohn Pedersen Fox (KPF), this angular, hanging platform is the "highest outdoor sky deck" in the western hemisphere. Known as Edge, the structure protrudes 24 metres from the 100th floor of 30 Hudson Yards in New York, and its glass floor provides a perspective of the far lower ground.
