Collectively, The Shanghai World Financial Center, The Shanghai Tower and The Jin Mao Tower form the world's first adjoining grouping of three supertall skyscrapers.

The Tornado Tower, also known as the QIPCO Tower, is a high tech office skyscraper in the city of Doha, Qatar. The building stands at a height of 640 feet (195 m) tall with 52 floors. Construction began in 2006 and has been completed in 2008. It's located on a 199,000 square foot plot of land, but only occupies 32,300 square feet of it, leaving plenty of open space around it to improve its aesthetic. The circular footprint of the building, using a 97-foot diameter at its base, includes a ground level restaurant and a bank, among other amenities. Sixteen elevators serve the approximate 904,000 square feet of office space the building contains. The building is accompanied by 1500 automobile parking spaces housed within three levels of underground basement parking. Due to the hour glass shape of the building, the total rentable office space available on each floor varies from 13,560--25,800 square feet. This provides high flexibility in both the size of office space available and the design of office space on each floor. The top three floors of the tower are luxury office space and are surrounded by terraces and balconies. The top level of the VIP floors has direct access to a helicopter landing pad. It's the tenth largest building in the city of Doha.
