The Dynamic Tower in Dubai is a proposed skyscraper that would have several innovative features. Each floor would be able to rotate independently, resulting in a constantly changing shape. The tower would also be the world's first prefabricated skyscraper, with 90% of each floor constructed in a factory. This modular construction would allow the entire building to be completed in just 22 months, over 30% faster than a traditional skyscraper. The tower aims to be self-sufficient in energy through wind turbines and solar panels located between and on the rotating floors. However, after facing delays from the financial crisis and other issues, construction on the Dynamic Tower is yet to begin.
