Worlds first rotating skyscraper

The Dynamic Tower (also known as Dynamic Architecture Building or the Da Vinci Tower) is a proposed 420-metre (1,378 ft), 80-floor tower in Dubai, United Arab Emirates.

The tower is expected to be architecturally innovative for several reasons:

Uniquely, each floor will be able to rotate independently. This will result in a constantly changing shape of the tower. Each floor will rotate a maximum of 6 metres (20 ft) per minute, or one full rotation in 90 minutes.

It will also be the world's first prefabricated skyscraper with 40 factory-built modules. 90% of the tower will be built in a factory and shipped to the construction site. This will allow the entire building to be built in only 22 months. The only part of the tower that will be built at the construction site will be the core. Part of this prefabrication will be the decrease in cost and number of workers (90 instead of 2,000 needed). The total construction time will be more than 30% less than a normal skyscraper of the same size. The majority of the workers will be in factories, where it will be much safer. The modules will be preinstalled including kitchen and bathroom fixtures. The core will serve each floor with a special connection for clean water, based on patented technology used to refuel airplanes in mid-flight.

The entire tower will be powered from wind turbines and solar panels. Enough surplus electricity should be produced to power five other similar sized buildings in the vicinity. The turbines will be located between each of the rotating floors. They could generate up to 1,200,000 kilowatt-hours of energy. The solar panels will be located on the roof.

Construction of the Dynamic Tower, is expected to be completed in 2010. The location of the Dynamic Tower has been finalised.
Each of the 80 floors in the world's first moving skyscraper will have offices and a hotel, topped by apartments. Designed by Italian architect David Fisher and located in Dubai (another is planned for Moscow), the prefab, wind-powered tower will cost an estimated $700 million. The residences will sell for $3.7 million to $36 million. The building should be completed in 2010.
