Extravagant plans were unveiled for the world's first swirling skyscrapers, with each floor rotating up to once an hour to form an ever-changing profile on the skyline. 

The rotating floors will be made of prefabricated units that spin around a concrete core. Most of the floors will be controlled from the architect's laptop, so that they are synchronised to make undulating architectural forms. Owners who buy an entire floor will be able to use voice activation controls to command it to rotate at will, so that they can pick their view.

Production of the prefabricated units is scheduled to begin in the next few weeks at a factory outside Bari, in Italy. Mr Fisher said that buyers should be able to move into the completed building in Dubai by the end of 2010. Details of the financing remain unclear because the developers are relying on pre-sales for at least part of the $700 million (£355 million) cost of building the 80-storey skyscraper. 

The project is being handled by a British-based company, Rotating Tower Dubai Development, Mr Fisher said. The 70-storey Moscow project will be developed by the Mirax Group in the new area of the city inside the third ring road. Mr Fisher said that he hoped a third “dynamic tower” would be built in New York and others eventually in cities such as London.

The buildings have to overcome several technical challenges such as connecting the plumbing with the same kind of shut-off valves used when refuelling aircraft in flight. To take the lift, residents have tostep from the rotating floor into the stationary central core.

By prefabricating the rotating units, Mr Fisher said, he can save at least 10 per cent of normal construction costs. He estimates it will take only six days to assemble each floor around the concrete core.

Plans require the buildings to be self-powered by horizontal wind turbines that spin between each floor to generate electricity. Solar power will be provided by photovoltaic cells on the roof of each rotating floor, 15 per cent of which will be exposed to sunlight at any one time.

The entire building will take 22 months to be built. The only part of the tower that will be built at the construction site will be the core. 

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.

The turbines will be located between each of the rotating floors.

It will have revolving floors, some of which will move on command, that will provide residents with an ever-changing shape along with a different view of The Persian Gulf and Skyline.

The shape will be determined by each floor's direction of rotation, speed, acceleration and the timing; with timing meaning how each floor rotates compared to the other. The rotation speed will be between 60 minutes and 24 hours for one revolution.

Residents, if they own the entire floor, are able to control the speed and direction of the rotation by voice command.

In 2008, the designer of the Dynamic Tower said that he expected it to be completed in 2010.

David Fisher, the architect of the Dynamic Tower, is an Israeli-born Italian architect in Florence.

He graduated from the University of Florence and also was a lecturer of architecture and structural engineering at the same university.

He has designed a series of rotating towers. The Dynamic Tower is Fisher's first skyscraper design.

    Our group has selected this building design because it is intriguing on how it will be manufactured and how intricate the design plans are. The fact that it can revolve is unbelievable. Also the views from the tower, while still and revolving are surreal. The Dynamic Tower is a huge breakthrough for modern architecture and is unique to any other building on earth today.

“My buildings are unique because they are the first ones to rotate — to be dynamic — every second.”
