A building that never looks the same-not once in a lifetime. That is how the Italian architect of the world's first moving building describes his planned 80-story tower, which will be built in Dubai.

The Dynamic Tower design is made up of 80 pre-fabricated apartments which will spin independently of one another. The revolving floors give the structure a "shifting shape."

"It's the first building that rotates, moves, and changes shape," said architect David Fisher.

The 1,378-foot building's apartments would spin a full 360 degrees, at voice command, around a central column by means of 79 giant power-generating wind turbines located between each floor.

Fisher said the building would be energy self-sufficient as the turbines would produce enough electricity to power the entire building and even feed extra power back into the grid.

The apartments, which will take between one and three hours to make a complete rotation, will cost from $3.7M to $36M.

"I call these buildings designed by time, shaped by life," said the Florence-based architect, who has never built a skyscraper before. "These buildings will open our vision all around, to a new life."

The skyscraper will cost an estimated $700m to build and should be up and running in Dubai by 2010.
