The Pentominium was a planned 122-storey, 517 m supertall skyscraper located in Dubai, United Arab Emirates. Construction on the tower was halted in August 2011. It was designed by Andrew Bromberg of architects Aedas and funded by Trident International Holdings. The AED 1.46 billion (US$400 million) construction contract was awarded to Arabian Construction Company (ACC). Construction started on 26 July 2008. Before construction stopped, the building was expected to be completed in 2013. By May 2011, 22 floors had been completed. However, in August 2011, construction stopped after Trident International Holdings fell behind on payments for a US$20.4 million loan following the global financial crisis. Had the project been completed as scheduled, the Pentominium would have been the second tallest building in Dubai after Burj Khalifa and the tallest residential building in the world, surpassing the 472.4 m Central Park Tower in New York City.

Six Senses Residences Dubai Marina

After being abandoned for 12 years, in December 2023, Select Group acquired the long-stalled Pentominium Tower. The Pentominium was completely redesigned from the ground up by Woods Bagot, utilizing the already built structure into the new design. In March 2024, the tower was rebranded and renamed as Six Senses Residences Dubai Marina. Upon its completion, Six Senses Residences Dubai Marina will have 122 stories and will be 517 m / 1,696 ft tall making it the tallest building in the Dubai Marina and potentially the tallest residential building in the world. Construction restarted in 2024. It is expected to be completed by 2028.
